Temperature Control Systems of Electric Machines
NT538-AD
Code: 1CN0137
N. & type inputs: 8 Pt100
Outputs: 5 relays + RS485 and 4.20mA
Plus: UL, RINA, EN50121-5
Electronic microcontroller based unit for the temperature monitoring of electric motors and MV dry type/cast resin transformers, the NT538AD, due to the 8 input channels and the multiple 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 thanks to the versatility of the new edition 2016, other sensor inputs are available.
It is equipped with 5 dry contact relay outputs, ALARM and TRIP, FAULT for working anomalies and drive of FAN1 and FAN2 cooling system.
On request, the unit is available with certification for Canadian and American market cULus, as well as RINA for marine applications.
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.
