Programmable timer relay

A programmable timer relay is an electronic device that combines the functions of a timer and a relay, allowing users to set specific time delays for switching electrical circuits on or off. Essentially, it acts as an automated switch that operates based on pre-programmed time intervals. This enables the automation of various processes and equipment across a wide range of applications.

How it Works

Programmable timer relays incorporate internal circuitry (often microcontrollers or digital logic chips) that allow for precise timekeeping and control. Here’s a general overview of how they function:

  1. Control Signal: The programmable timer relay receives an input or “trigger” signal, which initiates the timing process. This signal can come from a switch, sensor, or another control device.
  2. Timing Mechanism: Once the signal is received, the internal timing mechanism begins to count down or up based on the programmed parameters.
  3. Delay Period: During this delay, the relay’s contacts remain in their initial state (either normally open or normally closed).
  4. Contact Switching: Once the programmed delay period elapses, the relay’s contacts change state, either closing to allow current to flow or opening to interrupt it.
  5. Maintaining State & Resetting: The relay maintains its new state until the input signal is removed, or a reset function is triggered. Programmable relays offer various timing modes, such as:
    • On-delay: The relay activates after a set delay once the input signal is applied.
    • Off-delay: The relay deactivates after a set delay once the input signal is removed.
    • Interval: The relay activates for a set period and then deactivates.
    • Cyclic: The relay repeatedly alternates between on and off states for specified durations.

Users can typically configure these timing modes and sequences through a digital interface, often with an LCD or LED display for easy setup and monitoring.

 

Applications

Programmable timer relays are incredibly versatile and are used in numerous applications to enhance efficiency, save energy, and improve safety:

  • Industrial Automation: They control the sequencing of machinery, conveyor belts, pumps, and other equipment in manufacturing processes, ensuring precise timing and preventing system overloads.
  • Lighting Control: Used in homes, commercial buildings, and street lighting to turn lights on and off at specific times or based on ambient light levels, optimizing energy consumption and security.
  • HVAC Systems: Regulate fan operations, compressor cycles, and defrost cycles in heating, ventilation, and air conditioning systems to maintain desired temperatures and reduce energy use.
  • Security Systems: Implement delays for door locks, alarm systems, and surveillance cameras, allowing for controlled access and scheduled activation/deactivation.
  • Pump Control: Manage water pumps, sewage pumps, and sump pumps, ensuring they operate only when needed, which conserves water and prevents pump damage.
  • Home Automation: Automate various household appliances like irrigation systems, washing machines, and dishwashers.
  • Vehicle Systems: Control functions like intermittent windshield wipers and turn signals.

Delay relay 0.5 Sec – AC 24 V to DC 12 V

$62.15

Ship or pick up from our office.

Delay relay 0.5 Sec - AC 24 V to DC 12 V

A "delay relay 0.5 Sec - AC 24 V to DC 24 V" is a time delay relay that is designed to:
  • Operate with a control voltage of 24 volts, which can be either Alternating Current (AC) or Direct Current (DC). This dual compatibility (AC/DC 24V) is a key feature, as many relays are specific to one type of current.
  • Introduce a delay of 0.5 seconds before its contacts change state. This delay can be an "on-delay" (contacts close/open after 0.5 seconds when power is applied) or an "off-delay" (contacts remain closed/open for 0.5 seconds after power is removed), or other timing functions depending on the specific relay's design.
  • Switch or control a separate circuit, which may be a 24V DC circuit. The "AC 24V to DC 24V" in the description refers to the relay's input power compatibility (it can be powered by either 24V AC or 24V DC) and its output capability (it's often used to control 24V DC loads). It is not a direct AC to DC converter for the load it's switching, but rather indicates its flexible control voltage. The relay itself doesn't convert the power; it merely switches it on or off after a delay. If the controlled circuit specifically requires DC, the relay's contacts would simply switch the 24V DC power to that circuit.
Essentially, it's a versatile timing device used in control systems.   Purpose of Time Delay Relays Time delay relays are crucial in various applications where precise timing of electrical events is required. They serve to:
  • Prevent false triggering: A brief fluctuation in voltage or a momentary signal might cause immediate activation in a standard relay. A short delay (like 0.5 seconds) can prevent such nuisance activations.
  • Create timed sequences: In automated processes, certain steps may need to occur in a specific order with set delays in between. For example, a delay relay could ensure one motor starts before another or that a safety purge cycle completes before a furnace ignites.
  • Control motor starts/stops: They can be used for "soft starting" motors, gradually increasing voltage to reduce inrush current, or for ensuring a motor has fully stopped before another action begins.
  • HVAC systems: They prevent "short cycling" of compressors, which can damage the unit, by introducing a delay between successive starts.
  • Lighting control: Ensuring lights stay on for a set period after activation (e.g., in stairwells) or controlling emergency lighting.
  • Security systems: Providing a brief delay before an alarm triggers, allowing authorized personnel to disarm the system.
Types of Time Delay Relays While the "0.5 Sec" refers to the specific delay, time delay relays come with various functions:
  • On-delay (Delay on Make): The most common type. The contacts change state only after the set time delay has elapsed after the control voltage is applied.
  • Off-delay (Delay on Break): The contacts change state immediately when the control voltage is applied, but only return to their original state after the set time delay has elapsed after the control voltage is removed.
  • Interval: The contacts change state immediately when the control voltage is applied, and then return to their original state after the set time delay.
  • Repeat Cycle: The relay continuously cycles between on and off states with specific time delays as long as the control voltage is applied.
In the case of a "delay relay 0.5 Sec", it would likely be an on-delay or interval type, but the exact function would need to be confirmed from the specific model's datasheet.   AC/DC 24V Compatibility The "AC 24 V to DC 24 V" part primarily indicates the coil voltage compatibility of the relay. Many modern time delay relays are designed to accept a wide range of input voltages, including both AC and DC, within a specified range (e.g., 24V AC/DC). This offers flexibility in wiring and application, as the relay can be integrated into systems powered by either AC or DC at that voltage level. It's important to distinguish that this relay itself is not a voltage converter (like a power supply that converts AC to DC). Instead, it's a switching device. If the circuit you are trying to control requires DC and your power source is AC, you would need a separate AC to DC power converter (like a power supply unit) to provide the 24V DC to your load, which the relay's contacts would then switch.

Ship or pick up from our office.

Delay relay 0.5 Sec - AC 24 V to AC 24 V

delay relay 0.5 Sec - AC 24 V to AC 24 V is a type of electrical relay that introduces a 0.5-second time delay in a circuit, specifically designed to operate with a 24-volt AC (Alternating Current) power supply. This means that when the control voltage (24V AC) is applied or removed, the relay's output contacts won't change their state immediately; instead, there will be a half-second pause before they do. Here's a breakdown of what each part of the description means:
  • Delay Relay (or Time Delay Relay/Timer Relay): This is a control device that, unlike a standard relay, incorporates a timing function. It's used to control an event based on a pre-selected time interval.
  • 0.5 Sec: This specifies the duration of the time delay. In this case, it's a very short half-second delay. Time delays can range from milliseconds to hours or even days, depending on the relay.
  • AC 24 V (Input/Control Voltage): This indicates the type and voltage of the power supply required to energize the relay's coil or internal control circuitry. "AC" means Alternating Current, and "24 V" is the nominal voltage.
  • to AC 24 V (Output/Load Voltage): While not explicitly stated as "output," this implies that the relay is likely intended to switch a 24V AC load. This means the contacts within the relay are rated to handle 24V AC to control another part of the circuit or a device. It's important to note that the load voltage can sometimes be different from the control voltage, but in this specific phrasing, it suggests both are 24V AC.
How it Works A time delay relay operates using an internal timing circuit, which can be electronic (using components like capacitors, resistors, and microcontrollers) or electromechanical. When the input voltage (24V AC) is applied, the timing circuit is triggered. Once the preset delay (0.5 seconds) elapses, the relay's contacts will change their state (either closing normally open contacts or opening normally closed contacts), thereby activating or deactivating the connected load. Types of Delay Functions Delay relays come in various functions, and the "0.5 Sec - AC 24 V to AC 24 V" relay could be one of several types:
  • On-Delay (Normally-Open, Timed-Closed - NOTC): The most common type. When the control voltage is applied, the timing period begins. After 0.5 seconds, the output contacts close. The contacts remain closed as long as the control voltage is present.
  • Off-Delay (Normally-Open, Timed-Open - NOTO): When the control voltage is applied, the output contacts close immediately. When the control voltage is removed, the 0.5-second delay begins. After this delay, the contacts open.
  • One-Shot: Provides a single output pulse of a specified duration (in this case, 0.5 seconds) when triggered.
  • Repeat Cycle: Alternates between ON and OFF states for defined durations, creating a repeating cycle. This particular relay with a fixed 0.5-second delay is less likely to be a multi-function repeat cycle unless it's just one setting within a programmable unit.
To know the exact function, you'd need to consult the relay's datasheet or part number. Common Applications Delay relays are crucial in various control and automation systems where precise timing is essential. For a 0.5-second delay, typical applications might include:
  • Sequencing Operations: Ensuring one component starts or stops slightly after another in a controlled sequence.
  • Motor Control: Providing a brief delay before starting a motor (e.g., for pre-lubrication pumps to stabilize).
  • Safety Interlocks: Implementing a short delay to ensure certain conditions are met before an action can occur.
  • HVAC Systems: Timing the activation or deactivation of fans, compressors, or other components.
  • Conveyor Systems: Coordinating the starting or stopping of multiple conveyor belts to prevent material jams.
  • Lighting Control: For example, a short delay before turning on a light in a specific area

Door Strike Lock

An electric strike is an electromechanical lock release device that replaces a standard door strike plate.
It allows a door to be opened remotely, typically via an access control system, without manually retracting the latch. When activated, the electric strike releases the latch, enabling the door to be opened. 
Here's a more detailed explanation:
Functionality:
  • Replaces Standard Strike:
    Electric strikes are installed in the door frame, taking the place of the standard strike plate. 
  • Remote Release:
    They are designed to work with various access control systems, such as keypads, card readers, or intercoms. 
  • Activation:
    When an authorized signal is received (e.g., a code is entered, a card is swiped), the electric strike releases the latch, allowing the door to be opened. 
  • Fail-Safe or Fail-Secure:
    Electric strikes can be configured in either a fail-safe or fail-secure mode. 
    • Fail-safe: In this mode, the door unlocks when power is lost, making it suitable for safety applications where access is needed during power outages. 
    • Fail-secure: In this mode, the door remains locked when power is lost, requiring power to unlock, making it suitable for high-security applications. 
How it Works:
  • The electric strike contains a solenoid, which is an electromagnet.
  • When the solenoid is activated by an electrical signal, it moves a component (like an armature) that allows the latch to move freely.
  • This movement releases the door, allowing it to be opened. 
Key Differences from Other Locks:
  • Electric vs. Magnetic Locks:
    Unlike magnetic locks, which use powerful magnets to hold the door closed, electric strikes release the latch mechanism. 
  • Remote Access:
    Electric strikes offer remote access control, allowing doors to be unlocked without manual intervention. 
  • Versatility:
    They can be used with various locking mechanisms, including cylindrical, mortise, and rim exit devices.  
Common Applications:
  • Access Control:
    Electric strikes are a core component of access control systems in commercial and residential settings. 
  • Security:
    They provide a higher level of security compared to standard locks, especially when used with fail-secure configurations. 
  • Safety:
    In fail-safe configurations, they ensure safe egress during emergencies. 
  • Specific Areas:
    They are commonly found in reception areas, daycare centers, and other locations where controlled access is needed.

Double swing gate opener –VDS EGO110

More information about the swing gate openers: WHAT ARE THE DIFFERENT TYPES OF SWING GATE MOTORS? 1- Articulated Arm for Swing Gate Operators How do automatic gates work with articulated swing gate motors? An articulated arm electric gate opener uses a two-part arm with an ‘elbow’ joint to connect the motor to the gate. This arm protrudes from the gate motor body, so there has to be room for the arm to move as the driveway gate opens and closes. This type of electric gate opener is easier to install than other types, thanks to the geometry of the arm system. They can be slightly more expensive than other gate motors, but they open and close automated gates quickly. Many homeowners like discrete gate automation systems, and articulated arm motors can be more obvious when installed. However, many have the control system built into one of the motors. These motors for automatic gates are mounted on the inside of gates so they’re not seen from the outside of closed gates. In the event of power failure or mechanical breakdown, articulated arm motors can normally be released manually from outside the gate with an optional cable release system. All articulated arm gate operators are electric gate motors that can be either 120VAC or 24VDC. All 24V and some 120V versions have obstacle detection. This means that the gates stop moving and some even reverse when they come into contact with an object during operation. Articulated arm gate automation systems can be the best choice where each electric gate opener is mounted on a large gate pier or pillar. 2- Ram And Linear Screw Automatic Swing Gate Openers Ram gate automation motors push and pull a piston mounted on the gate. Linear screw electric motors for gates use an electric motor to rotate the gate mounting along a threaded shaft. Both types of electric gate motors are slim and don’t need a lot of space to operate. However, this advantage does mean that they require careful alignment during installation. Manual release systems are only available from inside the driveway gate. A ram or linear screw type of motor for automatic gate control is attached to the gate at one end and the gate pillar or post at the other end. Ram motors can be hydraulic or driven by electric motors, but all require a separate control box. As with articulated arm motors, 120Vac, and 24Vdc, you can buy versions with obstacle detection for safer operation. Additionally, heavy-duty versions of each type of electric gate opener are available that will operate larger gates with leaves up to 7m long. These electric gate openers can be the best gate automation solution when price is important. Their simpler design and operation can make them a cost-effective solution compared to other types of electric gate motors. 3- Underground Swing Gate Operators Many Canadian homeowners choose underground gate automation motors because they are very discreet. This is because each underground gate opener is hidden under the hinge end of each swing gate. But how do automatic gates work when they’re opened and closed by hidden underground motors? During installation, a carefully positioned hole must be dug to house a foundation box for each underground gate opener. The housing for each underground electric gate motor needs sufficient drainage to prevent the motors from sitting in water, or they will fail. Underground electric gate motors don’t need a lot of space to operate and can be installed on the inside or back of gate pillars. They are usually only installed behind gate pillars when the gates must open more than 90 degrees, so that the post or pillar does not obstruct the gates. With the addition of a 180-degree gate opener, your gates can open much wider than 90 degrees. This is an optional chain drive system for driveways that bend around behind the gate pillars. If the gate only opened to 90 degrees, it could block part of the driveway. But a 180-degree gate opener system means that it can keep going past 90 degrees, so it doesn’t block the driveway. Normally, underground automation of gates is the most expensive solution, but they are almost invisible. It is possible for the most powerful underground gate opener to open and close a swing gate up to 5m long. Underground motors for automatic gates can be manually released from outside the gate. These types of gate motors can be either hydraulic or electromechanical. A separate control box is required, and 120VAC and 24VDC versions with obstacle detection are available. Underground gate opener installation is not simple, and it should always be installed by professional electric gate engineers. Underground gate automation could be the best style for you if you want a discreet, almost invisible electric gate motor installation and you have the budget for this more expensive option.

A gate opener safety sensor is a crucial component of automated gate systems designed to prevent accidents and damage by detecting obstructions in the gate's path.
These sensors, often photoelectric, use an infrared beam to monitor the area and trigger the gate to stop or reverse if something is blocking its movement. 
How it works:
  • Transmitter and Receiver:
    A safety sensor typically consists of a transmitter that emits an infrared light beam and a receiver that detects the beam.
  • Obstruction Detection:
    When an object, person, or vehicle interrupts the beam, the receiver signals the gate operator to stop or reverse the gate's movement.
  • Safety Feature:
    This mechanism prevents the gate from closing on anything or anyone, ensuring safety and preventing potential damage. 
Types of Safety Sensors:
  • Photoelectric Sensors (Photo Eyes):
    These are the most common type, using an infrared beam to detect obstructions. 
  • Safety Edges:
    These sensors are typically placed along the edge of the gate and trigger a stop or reverse when they encounter pressure. 
  • Induction Loops:
    These sensors are embedded in the ground and detect vehicles as they pass over them, triggering the gate to open or close. 
Importance:
  • Safety:
    The primary function is to prevent accidents and injuries by stopping or reversing the gate when an obstruction is present. 
  • Preventing Damage:
    By detecting obstructions, these sensors help avoid damage to the gate, vehicles, or anything else in its path. 
  • Compliance:
    Safety sensors are often required for automated gates to meet safety regulations and standards. 
Common Issues:
  • Misalignment:
    If the sensor is misaligned, the infrared beam may not reach the receiver, causing the gate to malfunction.
  • Obstructions:
    Debris, dirt, or other obstructions can interfere with the beam and trigger false alarms.
  • Sensor Failure:
    Like any electronic device, sensors can fail over time, requiring replacement.

A swing gate opener is a device that automates the opening and closing of a swing gate, typically using a motor and a control system.
It provides a convenient and secure way to control access to a property, whether residential, commercial, or industrial. These openers can be used with various gate types, including those that swing inward or outward.

Here's a more detailed explanation:
How it works:
  • Motor:
    A motor, powered by electricity (AC or DC), provides the force to move the gate. 
  • Control System:
    A control board receives signals from a remote control, keypad, or other access control system and activates the motor accordingly. 
  • Opening Mechanism:
    Depending on the type of swing gate opener, the mechanism can be a linear arm, an articulated arm, or an underground system. 
  • Safety Features:
    Many swing gate openers include safety features like obstruction detection, which stops the gate if it encounters an obstacle during opening or closing. 
  • Emergency Release:
    An emergency release mechanism allows manual operation of the gate in case of power failure. 
Types of Swing Gate Openers:
  • Linear Arm: These are the most common type, using a linear actuator to push or pull the gate. 
  • Articulated Arm: These use a hinged arm to move the gate, reducing strain on the hinges. 
  • Underground: The motor and mechanism are installed underground, providing a more discreet appearance. 
  • Dual Swing: These openers are designed for gates that swing open from the center. 
Benefits of using a swing gate opener:
  • Convenience: Automatic opening and closing of the gate with the press of a button or remote control.
  • Security: Prevents unauthorized access to the property.
  • Enhanced Property Value: Adds a layer of sophistication and security to the property.
  • Accessibility: Can be particularly useful for people with mobility issues.
