The communication modules allow for connecting  telecom power systems into computer supervision systems and their remote monitoring. They are connected to the RS-232 serial port available in some MERAWEX power systems. The communication takes place via the Internet. The module casing is designed for mounting on the TS35 rail.

The SI48-ZM-MK modules provide the basic parameters of the telecom power system operation via the WWW and the SNMP agent. The web interface enables remote monitoring of the power system operation by using a typical internet browser. The modules enable access to the controller's registers by means of the SNMP interface. The modules inform about a device status via the SNMP traps.
