Electronic microprocessor based unit for the temperature monitoring of electric motors and MV dry type/cast resin transformers. The unit, due to the 8 input channels and the various programming options, grants a great flexibility of use in many applications.
It is equipped with 8 inputs for Pt100 sensors and with 4 dry contact relay outputs, ALARM and TRIP, FAULT for working anomalies and drive of FAN cooling system.
The unit can also communicate remotely with the protocol Tecsybus, allowing the connection of the external optional TECSYSTEM modules, RS485 Modbus output (BUSMOD 8/A), 4-20 mA analogue output (CONV 8/420/A), Ethernet output with IEC61850 protocol (CONV 61850), expansion relays (MOD RL8/A).
Upon request the unit is 
certified for the American and Canadian markets.
