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.
