Can I connect thermocouples and thermocouple cards to the PLC-cabling system?
No. The reason for this is the incompatibility between the connections of the cable header and the terminal blocks where the thermocouple would be connected. Because thermocouple cards are designed specifically for specific types of thermocouple wiring, there is a material incompatibility with a cabling system. The type of cabling that Phoenix Contact uses for standard PLC-cabling solutions is not conducive of a thermocouple wire. At the connection point where the thermocouple wire would be connected to the module, the terminal block would have to be a specific type of material as well as the cabling material itself. To use thermocouples with a PLC-Cabling solution a different type interface is required. Typically an analog input card would be used in conjunction with a specific Temperature in / Analog out conversion module. This would allow the connection of a thermocouple outside of the control cabinet and using standard copper wire to connect to the controller. By using an analog ca
