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:- 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.
- Timing Mechanism: Once the signal is received, the internal timing mechanism begins to count down or up based on the programmed parameters.
- Delay Period: During this delay, the relay's contacts remain in their initial state (either normally open or normally closed).
- 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.
- 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.
- 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.
- Versatility and Customization: They can be programmed for various timing functions and sequences within a single unit, offering great flexibility for diverse applications.

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

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.
- 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.
- 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
Power inverter 110 V to 220 V
Ship or pick up from our office.
Power inverter 110 V to 220 V
A power inverter 110V to 220V (also known as a step-up voltage converter) is an electronic device that transforms an input voltage of 110 volts (V) into an output voltage of 220V. This type of inverter is crucial for bridging the gap between different regional electrical standards. How It Works At its core, a 110V to 220V power inverter utilizes a transformer to achieve the voltage conversion. Here's a simplified explanation:- Input (DC to AC Conversion for Inverters): While the prompt asks about a "power inverter 110V to 220V," it's important to clarify that traditional inverters convert DC (Direct Current) from a battery (e.g., 12V, 24V, 48V) into AC (Alternating Current). If the input is already 110V AC, then the device is more accurately called a voltage converter or transformer, as it's stepping up AC to AC. However, some inverters are designed to take a DC input and produce 110V AC or 220V AC, or even both.
- Step-Up Transformation: For a 110V AC to 220V AC conversion, the device contains a transformer with primary and secondary coils. The 110V AC from the power source is fed into the primary coil. Through electromagnetic induction, this voltage is "stepped up" to 220V in the secondary coil, which then becomes the output.
- Waveform: Inverters and converters can produce different types of AC waveforms:
- Pure Sine Wave: This is the most desirable waveform, replicating the smooth, consistent power from a utility grid. It's ideal for sensitive electronics.
- Modified Sine Wave: This is a cruder approximation of a sine wave and is generally suitable for less sensitive appliances, but can cause issues or damage with certain delicate electronics.
- Power Capacity (Wattage): This indicates how much power the device can supply. Ensure it's sufficient to handle the total wattage of the appliances you intend to connect. Exceeding the inverter's capacity can lead to damage.
- Efficiency: A higher efficiency rating means less energy is wasted as heat during the conversion process, which is important for battery-powered setups.
- Safety Features: Look for features like overload protection, short-circuit protection, and surge protection to safeguard your appliances and the inverter itself.
- Frequency: Electrical grids operate at either 50 Hz or 60 Hz. Ensure the inverter's output frequency matches the requirements of your appliances. Some inverters can switch between frequencies.
- Portability: Some are designed for travel, while others are larger for industrial or home use.
- International Travel: They allow travelers from countries with 110V systems (like North America) to use their 220V appliances (like hair dryers, chargers) in countries with 220V outlets (common in Europe, Asia, and other regions).
- Using Imported Appliances: If you have an appliance designed for 220V (e.g., a European kitchen appliance) but your home has 110V outlets, a step-up converter enables you to use it.
- Industrial and Specialized Applications: In industries, they can be used for automation and control systems, telecommunications, and emergency power systems to ensure compatible power supply for various equipment.
- Renewable Energy Systems: In off-grid solar or wind power setups, inverters convert DC power from batteries into the required AC voltage (which could be 110V or 220V depending on the load).
- High-Power Appliances: Some larger appliances or specialized tools might require 220V power, even in regions where 110V is standard for most household items. A converter can provide the necessary voltage without extensive electrical rewiring.
