GFX4 Power controller 4 PID loops up to 80kW



  • GFX4 is a four-independent loop controller, designed to manage electrical power. GFX4 is a compact unit bounding different technological elements like:
    • controller
    • solid state relay
    • current transformers
    • fuses-holders (option)
  • The final result is a cost-saving in terms of space and cabling.
  • GFX4 consisting of:
    • power management unit
    • analog and digital inputs
    • analog and digital outputs
    • standard digital communication
    • integrated solid state relays
    • fuses-holder (option)
  • Geflex controls autonomously the four loop controllers, furnishing complete diagnostics like the loaded current, the control of the zones, and the alarms state.
  • A specific step-by-step software tool has been developed in order to assist the product configuration based on the different applications.
  • Communication with the outside is of primary importance.
  • Geflex dialogs with the operator terminals according to the most popular protocols: from the simple and efficient Modbus to, by a second optional Fieldbus communication, the by-now indispensable Profibus DP, CANopen, DeviceNet, Modbus RTU, Ethernet Modbus TCP.
  • The product’s furnished with a standard configuration, simple and quick to modify. The assignment of different functions to the outputs is very simple.


Ideal for control of mono-bi-tri-phase 30, 60, 80 kW resistive loads.
