TIME CIRCUIT-PULSE STRETCHER
This unit is a solid state timing circuit that is capable of driving an automotive Bosch-type relay and operates on a constant source of +12VDC and chassis ground. With two triggers per circuit, the positive trigger will activate the timer when it is pulsed with 12 VDC. The negative trigger will activate the timer when it is pulsed with chassis ground. The output lead supplies +12VDC to drive the 20/30 AMP relay. One to 30 second variable time duration and an LED light indicates if timing cycle is over.
