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

The VCM-04 and VCM-04-10SA is a two input, one output “off” 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 inactive (off). When the timer expires, the output will turn off and the operation is complete.
