Product CODE
:
1CN0007
DESCRIPTION
:
Electronic microprocessor based unit to control the oil and windings temperature of oil transformers. This unit is able to directly measure the oil temperature and calculate the temperature of the windings, knowing the load current through thermal imaging TECSYSTEM’s algorithm. Equipped with 1 input for a double Pt100 sensor for measuring the oil temperature and 1 input for current transformer (5A max) for the load current. Five outputs with dry-contact relays are included, ALARM and TRIP, FAULT for working anomalies and drive of FAN cooling system or pumps (FAN and FAN2). The unit can also communicate remotely with the protocol Tecsybus, allowing the connection of the external optional TECSYSTEM modules, BUSMOD 8/A, for RS485 Modbus output and the MULTIMODULE 133 for expansion relays.
