12V Alternating Latching Solid State Relay

A two input module that will latch and open output with either a momentary +12Vdc input or a momentary ground input. The two inputs operate as a logical “exclusive” or, so that either input can cause the output to alternately latch or unlatch. The output for the VCM-01 is +12Vdc and is normally open until it receives an input signal for more than 250 milliseconds. The alternating inputs must be removed for one second before being re-applied. The default state is output NO when first powered up.
