Solid State Relay with Built-In On-Delay Timer Function

The VCM-03 is a two input, one output “on” delay relay, which can be ordered with either an adjustable time delay or a fixed time delay. One input (87A) is +12Vdc and the other is Ground (87), operating such that either input will operate the timer. The timer begins when an input goes active, and if removed before the timer expires, the timer will reset. The output remains on until the input is removed.
