Multi-channel temperature controllers with Ethernet/IP
Gefran is adding Ethernet/IP communications to its GFX4 and GFXTERM04 multi-channel temperature controllers. The full-featured GFX4 family is now available with Ethernet/IP in addition to the existing choice of several fieldbus communication options, and the four-loop temperature controller is available in PID control only or as fully integrated versions complete with relays, current transformers and fuses - thereby offering savings in control panel space and faster installation.
The DIN rail, panel-mounted range measures just 25 x147 x 160mm and features configurable universal inputs, manual tuning or auto-tuning functions, as well as advanced diagnostics, with all interfacing via pluggable connectors. Aimed at demanding process automation applications such as plastic extrusion, injection moulding, thermoforming, wrapping and welding, the Ethernet/IP option enables expansion for up to 16 temperature zones by daisy-chaining up to four GFX4 controllers via Ethernet. The GFX4 also supports a master/slave configuration, which helps to reduce network wiring.
Ethernet/IP set-up is simplified with pre-configured GFX4 message blocks that are imported into the Rockwell RSLogix program. Multiple diagnostic functions include 'loop break alarm' and 'heater break alarm,' where alarm conditions such as broken probes, lack of load voltage and even partial load failure may be monitored and immediately identified with relay alarms and LED indicators.
Gefran's GXF4 is also available with fieldbus communication options including RS485 Modbus, Profibus, DeviceNet, CANopen and Ethernet (Modbus over TCP/IP or GDnet), with protocols for direct connection to PLCs, HMIs and industrial PCs with no need for further converters.
