30, 60, 80 kW in single phase and three phase


The GFX4-IR is a four independent loop controller, designed to manage electrical power.
It is a compact unit combining different technological elements like:
       • Controller
       • Current transformers
       • Solid state relay
       • Fuses-holders (option)

The GFX4-IR is managed by a microprocessor that independently controls the 4 control loops and also runs functions specifically designed to manage single phase and three phase loads, with low and high temperature coefficient, short wave and medium infrared lamps, and transformer primary circuits.
In terms of space and cabling it provides a significant cost saving.

The multiple activation methods are all software-configurable, and include:
- Zero crossing with constant cycle time for conventional loads
- Burst firing with variable cycle time for systems with low thermal inertia, medium wave

IR lamps
- Single cycle for short wave IR lamps with reduced flickering (half single cycle)
GFX4IR runs complete diagnostics of current, voltage, and temperature levels.
- Phase angle control with current limit for short wave IR lamps, transformer primaries, with assignment of soft start up and soft stop down options with limitation of maximum rms current.

Current
- Total and partial interrupted load alarm
- “Teach-in” function for self-learning of alarm threshold for interrupted load
- SCR in short circuit alarm
- Load in short circuit or in overcurrent alarm
- Unbalanced 3-phase load alarm

Temperature
- Over temperature alarm
Various feedback functions in the absence of PID control have been developed for complete control of loads in all types of applications:
- Voltage feedback (V) with current limit
- Current feedback (I)
- Power feedback with maximum power limit

Controller
30, 60, 80kW solid state relay
DIN rail or panel mounting
Current transformers
4 configurable output (option):
Relay / logic / TRIAC / continuous
Fuses-holder (option)
4 universal main inputs
4 main output internally wired to the SSR
4 heat/cool independent PID
4 auxiliary analog inputs (option)
Standard digital communication:
Modbus RTU
2 configurable relay alarm output
2 digital inputs
Optional Fieldbus communication:
Profibus DP, CANopen, Euromap66,
DeviceNet, Modbus RTU, Modbus TCP,
Ethernet IP

Configuration is changed by setting simple parameters with a software tool that guides the user to a correct and safe configuration. GFX4-IR dialogs with the operator terminals according to the most popular protocols: from the simple and efficient Modbus to (via a second optional fieldbus communication) the by-now indispensable Profibus DP, CANopen, DeviceNet, Modbus RTU, Ethernet Modbus TCP, and Ethernet IP.

The product comes with a standard configuration that is simple and quick to modify, for example, to assign different functions to outputs.
