Contact Closure Input Ports

The contact closure inputs on the IPL T CR48 are able to detect a closed circuit between any of the inputs and ground. The contact closure input ports use a 1k ohm pull-up resistor in a TTL (5 VDC) circuit to sense external switch or contact closure.

By connecting one side of an external switch or relay to the contact closure ground port and the other side to one of the four contact closure input ports, logic 1 (closed) can be produced. Logic 0 (open) can be produced by disconnecting either side of the external switch or relay from the IPL T CR48.
