The NT935-IR AD control unit coupled to the dedicated infrared sensors Tir409 allows control of the physical contactless temperature 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 the PT100 is not recommended for electric insulation and safety problems.

Unlike general market products, the NT935irad and TIR409 have been studied in order to operate even in very high electromagnetic fields, thus ensuring reliability and safety in the system itself.

The compact size makes the sensor easy to install on any flat surface, while the laser pointer allows you to check if it has been properly positioned.

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

Output relays are available for alarm, trigger, fan1 / fan2 and defect.

In addition to having all the new features introduced in the latest generation ED16 devices, including double display, the largest relay capacity, the unit is equipped with the voting and intellifan function and an RS485 Modbus RTU output and 4-20 mA analog for data remote management.

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

Universal food: With entry from 24 to 240 Vac-DC
