GFXTERMO4 is a multi-loop control system that controls four process loops in a completely independent manner. Configuration of I/O resources is very rapid and flexible thanks to a programming tool that guides the user in the selection of parameters. Each control loop has: 
• Process input 
• Input for external CTs or CT / linear input 
• Control output 
• Cooling output Other auxiliary I/Os: 
• Two digital inputs 
• Two relay outputs 
The use of two independent serial ports provides efficient communication ability. The two serials are defined as follows: 
• “local bus” to create a GFXTERMO4 network and connect it to an operator panel or industrial PC. Uses Modbus RTU protocol and reaches a speed of 115 Kbps. 
• “field bus” to integrate with architectures that already use industrial field buses such as: Profibus DP, CANopen, DeviceNet, Modbus RTU, Ethernet Modbus TCP. 
The presence of “intelligence” directly on the board lets the user create fully independent and reliable controls. The device installs on the DIN rod or with two M4 screws.
