On an Interval-Delay timer module with reset feature the output automatically activates as soon as input-1 senses a contact closure or impulse signal. Output signal will remain activated until the preset off-delay timing cycle has elapsed. At the end of this cycle, the output deactivates and remains inactive until a reset is performed by removing the main power from pin-4 or via the optional input-2 reset signal. Off-delay duration is specified when ordering and can be configured in milliseconds, seconds, minutes, hours or even days.
