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.
- 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

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.

Digital programmable ON/OFF relay
A digital programmable ON/OFF relay is an electronic switch that can be programmed to turn electrical devices on or off at specific times or intervals. It combines the fundamental switching functionality of a traditional relay with the advanced timing and control capabilities of a digital timer or microcontroller. This allows for automated control of various devices and systems without constant human intervention. How it Works At its core, a digital programmable ON/OFF relay operates similarly to a standard relay by using a small electrical current to control a larger electrical circuit. However, the "digital programmable" aspect introduces a sophisticated timing mechanism.- Digital Interface: Unlike mechanical or analog timer relays with physical dials, digital programmable relays feature an LED or LCD display and a keypad or buttons for programming. This allows users to set precise ON/OFF times, durations, and sequences.
- Microcontroller-Based: Most digital programmable relays use a microcontroller to manage the timing and control logic. This internal "brain" keeps track of time and executes the programmed instructions.
- Timing Functions: These relays offer a wide range of timing functions, including:
- On-delay: The relay turns on after a preset delay once activated.
- Off-delay: The relay turns off after a preset delay once deactivated.
- Interval timing: The relay stays on for a specific duration after activation.
- Cyclic operation: The relay repeatedly cycles ON and OFF at set intervals.
- Astronomic timing: Some advanced models can turn devices on/off based on sunrise and sunset times by calculating the solar position.
- Photocell integration: Others may include light sensors to activate based on ambient light levels.
- Memory Retention: Many programmable relays can store settings in memory even after a power interruption, ensuring that the programmed schedule is not lost.
- Programmable Timing: Offers precise control over when devices turn on and off.
- Automation: Reduces the need for manual operation, leading to increased efficiency.
