Описание
The ER3314 EtherCAT Box with analog inputs permits four thermocouples to be directly connected. The module’s circuit can operate thermocouple sensors using the 2-wire technique. Linearisation over the full temperature range is realised with the aid of a microprocessor. The temperature range can be selected freely. The error LEDs indicate a broken wire. Compensation for the cold junction is made through a temperature measurement in the connecting plugs. This means that standard extension leads can be connected. The ER3314 can also be used for mV measurement.
