The delay off time delay relay functions within power systems ranging from 12 to 240 volts of alternating current (AC) or direct current (DC). Upon receiving a trigger signal, the timer relay initiates an internal timer to either open or close a circuit. Even in instances of power loss, this timer persists in operation. When the predetermined delay period elapses, the relay switches its state, either closing or opening the relevant circuit.
This design finds utility across various applications, particularly those necessitating a delay in the deactivation of specific functions or devices subsequent to the cessation of primary equipment operation. Its capacity to operate without a power source renders it advantageous in settings characterized by unstable power supplies or requiring automatic power-off safeguards.
Feature
- The true delay off timer relay does not require auxiliary power supply, and the relay relies on internal energy storage capacitors to operate after power failure.
- Time range (adjustable by rotary switch and fi ne setting by potentiometer): 0.1s-10 mins.
- Voltage range: AC/DC 12-240V, clamp terminals.
- Relay status is indicated by LED.
- 1-MODULE, DIN rail mounting.

Tips: The benefits of using a time delay relay with delay off without supply power.
- Continued operation during power interruptions: Even in the event of power loss, the time delay relay continues to function, ensuring uninterrupted operation of critical systems or processes.
- Delay functionality: The relay provides a delay before shutting down or activating certain functions or devices, allowing for smoother transitions and preventing sudden disruptions.
- Enhanced safety: By delaying the deactivation of equipment or processes after power loss, the relay helps mitigate potential hazards and ensures safe operation in various environments.
- Automatic power-off protection: In scenarios where automatic power-off protection is necessary, such as in sensitive equipment or critical processes, the relay offers reliable safeguarding against unexpected power fluctuations or failures.
- Improved efficiency: The time delay relay optimizes the operation of electrical systems by allowing for precise timing control, leading to increased efficiency and reduced energy consumption.
- Adaptability to unstable power sources: The relay's ability to operate without a stable power supply makes it well-suited for environments with fluctuating or unreliable power sources, providing stability and consistency in operation.
