Gefran Gfx4 power controller - now also for IR heating control

Gefran GFX4: Providing

cost savings

in terms of space and cabling!

The automation of packaging, wrapping and welding machines requires compact “space-saving” solutions to ensure they can be incorporated within small electrics boards and panels. Standard communication between the machine and line devices is essential.

Designed specifically for these requirements is the GFX4 temperature control unit with four independent PID control loops, integrated solidstate relays for 30KW, 60KW, 80KW and removable fuses.

Performance is enhanced by the addition of communication ports with Modbus, Modbus TCP/IP, Profibus, DeviceNet and CanOpen protocols for direct connection, without any further converters, to devices such as PLCs and operator interfaces or Industrial PCs.

The GFX4 version includes, in a single DIN rail mounting enclosure, the four PID controllers and four solid state relays based on sturdy antiparallel double SCR technology. These are mounted on the ventilated heatsink. There is provision for four on-board current transformers, together with four extra-rapid fuses assembled on fuse holders.

With multiple diagnostic functions available, such as the “loop break alarm” and the “heater break alarm”, it is possible to monitor functionality of the loads and immediately diagnose, with relay alarms and LED indicators, broken probes; lack of load voltage; even partial load failure. One can also check for excess temperature conditions or short circuiting of the solid state relay. This integrated solution by Gefran offers considerable space-saving advantages within the panel and reduced assembly time, in addition to significantly reducing wiring requirements.

Now also for Infra Red heating control

Gefran launches the GFX4-IR, its advanced power controller with hardware and software functions specifically for IR (infrared) heating elements of any wavelength.

IR lamp heating technologies are being applied more and more often in industry, and provide concrete advantages over traditional heating devices.

They are used in a wide variety of industrial processes, from producing PET bottles to cooking foods in ovens, from finishing furniture to heat treating silicon wafers for photovoltaic panels. This applicative flexibility is typical of contactless technologies, in which the product is not (or must not be) in contact with the heating element.
