Gefran controls

GFX4

GFX4 is a four independent loop controller, designed to manage electrical power. The 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 & cabling. GFX4 consisting of:

• Power management unit

• analog and digital inputs

• analog and digital outputs

• standard digital communication

• integrated solid state relays

• fuse-holder (option)

Geflex controls autonomously the four loop controllers, furnishing a complete diagnostics like the loaded current, the control of the zones, 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 important. Geflex dialogs with the operator terminals according to the most popular protocols:

• Modbus

• fieldbus communication

• Profibus DP

• CANopen

• DeviceNet

• Modbus RTU

• Ethernet Modbus TCP

The product’s furnished with a standard configuration, simple and quickly to modify. The assignment of different functions to the outputs is very simple.

Features

• 4 zones of PID control

• Integrated Zero Cross Switching SSRs and Fusing (30 & 60 kW Model)

• 2 Digital Inputs

• 1 current transformer (standard) total of 4 available

• 2 alarm outputs

• Cooling outputs

• Modbus / fieldbus communications / profibus DP / CANopen / DeviceNet / Modbus RTU / Ethernet Modbus TCP (available option)

• Up to 80kW Switching on integrated SSRs

• Touch-safe package

• DIN rail or panel mounting

• 4 universal process input could accept:
  thermocouple, thermoresistance, current and tension linear.

• Self-tuning: calculation of PID parameters at syst

• Auto-tuning continuous: continuous adjustment of PID

• Auto-tuning one-shot: output modu and event-driven automatic PID parameters re-calculation.
