Who’s Watching your Communications Site? The DC-RMCU1……


The DC-RMCU1 (SITE CENTRI©) is designed by DuraComm to monitor any DC load, battery or power supply, temperature, and AC power via Ethernet. It is easily adapted to many possible power systems thanks to six isolated Volt or Amp meters that monitor critical data via Internet for analysis and site history logging.

8 general purpose I/O pins provide alarming and control. This compact unit can be rack, DIN-rail, or wall mounted.

Provides connectivity and adds intelligence to any site’s AC and DC power system for 24/7 monitoring, alarm condition notification, and data logging of vital electrical functions. All programmable, accessible, and managed via the Internet: TCP/IP or SNMP.

DuraComm also features power solutions integrated with remote monitoring and control in our new MU Series.
