Dual Input Module – FW812

Dual Input Module - FW812

The FW812 dual input module supports two Class B input circuits, each of which is able to monitor a dry contact device. The input line is monitored for open line faults and ground faults, and the contact must thus be wired with an end-of-line resistor.
