The D7053 Multiplex Input-output Module is a general purpose device that monitors a normally-open (NO), supervised contact device and provides a separately controlled Form C relay output. The module connects to the multiplex bus in either a Class A (Style 6) or Class B (Style 4) configuration. All operating power for the module is drawn from the control panel's multiplex bus.
