This timer protected by shrink tube can be set thanks to a field-adjustable rotary knob (with adjustment range from 1 to 180 s).
Fitted with a NO/NC contact (with breaking capacity of 24V DC – 3 A), it is suitable for locking devices operating in fail secure or fail safe mode, supplied with 12-24V AC/DC current.
Implemented in installations requiring a fail secure locking system receiving AC current, the delay time shall not exceed 45 s.
