RTU 101-IMS

RTU 101-IMS
for monitoring insulation- and loop resistance in copper cables

The monitoring station RTU 101-IMS is used to detect the penetration of moisture in copper cables, their squeezing or damage.

The readings of the 10 measurement channels, regarding insulation and loop resistance, are evaluated by the RTU 101-IMS according to individual user programmed parameters.

Threshold exceedings cause automatic reports like warnings, alarms etc. to assigned receiving stations.

The UMS server permanently polls the actual measurement and system data via intranet (Ethernet, TCP/IP). It evaluates the sensing points states and stores all data in the database of the UMS server.

All connections and control units are stored in awall mount housing. The connections are fixed by screws and clamps ensuring an easy and cost effective mounting without the need ofexpensive special cables.
