How do I connect a Thermocouple to a PLC?
Assigned a new task to add a thermocouple measurement to your PLC system, you ask yourself “How do I connect a thermocouple to a PLC?”.
A thermocouple transmitter allows a thermocouple to be signal conditioned to be more easily used.
A thermocouple is a low cost accurate temperature sensor. It is easily connected using standard accessories.
A thermocouple transmitter converts the thermocouple voltage change to 4-20mA current change. The 4-20mA signal allows the thermocouple, when using a transmitter, to be connected to a PLC. This allows a thermocouple to be used as a part of a modern control system.
