Visión general

An innovative, integrated system to control power and temperature, designed for industrial electric heating processes.

The system architecture is optimized for temperature control of multizone plants.

It consists of a control unit, i.e., the PID microprocessor controller plus load control device (AT and VT), and a power module (SSR) with aluminum heat sink.

The system is compact and easy to install and use.


Ideal for control of resistive loads from 25 Amperes to 120 Amperes

  • Three versions:
    MASTER - independent temperature control and communication unit
    SLAVE - independent temperature control unit
    EXPANSION - for three-phase loads
  • SSR (Solid State Relay) zero crossing
  • Rated voltage: 480Vac rms, 50-50Hz
  • Rated current (AC1): 25A, 40A, 60A, 90A, 120A
  • Protection: IP20
  • Installation: DIN bar and panel
  • Universal temperature input, accuracy 0.2%
  • Configurable digital input
  • Logic output or "cooling" relay
  • Load current detection with integrated CT
  • Heat/cool PID, selection of cooling fluid, self-tuning,auto-tuning, soft-start
  • 4 generic alarms, LBA and HB alarms
  • 2 configurable relay outputs
  • Serial: RS485 optically isolated "Modbus RTU" serial protocol
  • Field bus: PROFIBUS DP, CANopen
