SC – Signal Conditioner Digital Transducer

SC – Signal Conditioner Digital Transducer Digitalizes values of temperature, tap position, current, voltage and contacts by generating serial outputs (DNP3.0/Modbus) plus analog and contact communication. Digitalizes alarm/trip contact status from intelligent SCA High-Speed Relay outputs.

Transducers are applied in substations and high voltage and industrial plants to convert signals of different nature – like temperature,  AC or  DC voltage, AC or  DC current, current  mA loops,  dry or energized  contact  status  and  tap  position,  among  others  – into standardized  outputs for transmission  to online data  acquisition,  supervision and/or monitoring systems.

Treetech’s SC transducer performs this task digitally by converting input signals into programmable analog outputs such as 0-1 mA, 4-20mA and others, and into RS485 serialcommunication with open protocols, as well as providing output contacts for signalling and alarms.

Specifically developed for the severe environmental andelectromagnetic conditions of high-voltage substations, the SC withstands extreme temperatures, transientovervoltages and electromagnetic interference that would harm or make inoperative similar industrial class equipment. The SCs main characteristics are:

  • Models available  for measurement  of up to 6 temperature  sensors, 4 AC or  DC voltages, 4 AC or  DC currents, 12 current loops in mA, status  of up to 12 dry or 4 energized contacts and 3 tap positions;
  • Digitalization of alarm/trip  contact status from Treetech’s High-Speed SCA Relay  intelligent output bus;
  • Up to 4 user programmable analog looped outputs (e.g.: 4-20  mA);
  • A RS485 serial port with DNP3.0 or Modbus RTU open protocols;
  • Two alarm/signalling  contacts with user programmable operation logics;
  • Entry signal and transducer self-diagnostics with signalling contact;
  • Universal auxiliary supply between 38 and 265  Vdc / Vac, 50 / 60 Hz;
  • Galvanic insulation between inputs, outputs and power supply.
