TR-100 digital temperature control relay is designed for measurement and control of temperature parameters from 4 sensors with subsequent display of measured values in the front LED display panel and alarm signalization if any of controlled parameter comes out of user defined range.

Applications:

Thermal protection of motors and generator

Protection of 3 phase dry transformer equipped with the core temperature control or ambient temperature control

TR-100 has universal power supply input and may work from any AC/DC power between 24V to 255V regardless of polarity. 

TR-100 has built in RS-485 interface MODBUS RTU to transfer the information to upper level dispatcher system.

On special request it is possible to make several programmed modifications and extend the functions to control and regulation by other devices. Also, it is possible to use TR-100 in SCADA systems.
