Bosch D7053 Multiplex Input-output Module.

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 D7053 connects to the multiplex bus in either a Class A (Style 6) or Class B (Style 4) configuration. All operating power for the D7053 module is drawn from the control panel’s multiplex bus. Rotary switches allow convenient address setting. An onboard status LED on the module indicates normal, alarm, and trouble conditions and is visible on the module or on an attractive, low-profile faceplate.
