The InPower Time Delay Relays are completely solid state adjustable on-delay or off-delay timer relays with a single +12 volt @ 15 amp output. The module has two inputs, one actuated by a transition to +12 volts (Input A) and one actuated by a transition to ground (Input B). The two inputs operate as a logical “Exclusive OR” so that either input can cause the timer to operate.

When an input is applied and maintained, the timer will start. When the timer expires the output will be activated (VCM03 series) or de-activated (VCM04). The output will remain in the desired state until both inputs are open (cleared). The time period is adjustable with a single turn potentiometer. Four time ranges are available: 0-10 seconds, 0-60 seconds, 0-3 minutes, and 0-10 minutes.

The timer will start when +12 volts is applied to Input A while Input B is open, or when ground is applied to Input B while Input A is open. The input must be maintained to operate the timer. If removed during the timer operation (before the timer expires) the operation will reset. The output is rated at +12 volts @ 15 amps and provides over current and short circuit shut down.
