On an Off-Delay timer module the output automatically turns "ON" when the input or combination of inputs are "NOT" in an active state. Once the input(s) has activated, a timing sequence will begin, keeping the output energized until the preset Off-Delay time has elapsed. This Off-Delay duration is specified when ordering and can be configured in seconds, minutes, hours, or even days. Any inactive state on the input(s) will cause the output to switch back "ON" and timing sequence will restart.
