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.
Developed with layout and advantages of the new technology platform (dual display, VOTING function, new microcontroller with increased operational capacity and data management), the NT538 AD provides the user, in a single product, the outputs:
– Analog 4-20mA
– Digital RS485 Modbus.
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.
UNIVERSAL POWER SUPPLY: with input from 24 to 240 Vac-dc
