The NT538AD, based on an electronic microcontroller for monitoring the temperature of electric motors and dry MV transformers, thanks to the 8 input channels and the multiple programming possibilities, offers great flexibility in many applications.

Developed with the layout and advantages of the new technological platform (dual display, VOTING function, new microcontroller with operational capacity and increased data management), the NT538 AD provides the user, in a single product,

  • 4-20 mA analog
  • Modbus digital RS485

It is equipped with 8 inputs for Pt100 sensors and thanks to the versatility of the new 2016 edition, other sensor inputs are available.

It is equipped with 5 dry contact relay outputs, ALARM and TRIP, FAULT for operating anomalies and the drive of the FAN1 and FAN2 cooling systems. 
On request, the unit is available with certification for the Canadian and American market, as well as for marine applications.

All our units can also be supplied with a special coating on electronic cards, resistant to harsh weather conditions, particularly characterized by high temperature and humidity (which are in tropical climates).


UNIVERSAL SUPPLY: with input from 24 to 240 Vac-dc.
