Datasheet NT935 IR AD ITA-ENG.pdf


The control unit NT935-IR AD coupled to the dedicated infrared sensors TIR409 allows the temperature control without physical contact between the sensor and the surface to be measured.

This characteristic makes it useful to control the temperature of medium or high voltage windings, where the use of PT100 is not recommended for the problems of electrical insulation and the security.

Unlike general products on the market, the NT935IRAD and TIR409 were studied in order to work even in very high electromagnetic fields, thus ensuring reliability and security to the system itself.

The compact size make the sensor easy to install on any flat surface, while the laser pointer helps to verify if it has been correctly positioned.

The unit is equipped with 3 inputs, to control the temperature of the 3 windings and a fourth additional input.

Output relays are available for ALARM, TRIP, FAN1 / FAN2 and FAULT.

As well as have all the new features introduced in the latest ED16 generation devices, including dual display, most capacity of relays, the unit is equipped with the function Voting and Intellifan and RS485 Modbus RTU and 4-20mA Analog output for data remote management.

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

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