Description

Beckhoff EL3312 | 2-channel thermocouple input terminal Beckhoff. The EL3312 analog input terminal allows thermocouples to be connected directly. The EtherCAT Terminal's circuit can operate thermocouple sensors using the 2-wire technique. Linearization over the full temperature range is realized with the aid of a microprocessor.
