CJC Jumpers: Why are they needed in Thermocouple PLC Modules?
CJC jumpers are cold junction compensators used in analog thermocouple PLC modules. To better understand the concept of Cold Junction Compensation (CJC) with CJC jumpers, let’s first review what is a thermocouple and its working principle. What is a Thermocouple? A thermocouple is a sensing device that measures temperature, it’s basically a high-temperature range thermometer. […]
