2-channel thermocouple input terminal Beckhoff EL3312. The EL3312 analog input terminal allows thermocouples to be connected directly. The Ether CAT Terminal & circuit can operate thermocouple sensors using the 2-wire technique. The temperature range can be selected freely. The error LEDs indicate a broken wire Compensation for the cold junction is made through an internal temperature measurement at the terminal. The EL3312 can also be used for mV measurement.
