Beckhoff EJ3214 EtherCAT plug-in module

Beckhoff EJ3214 EtherCAT plug-in module

The EJ3214 EtherCAT plug-in module allows four resistance sensors to be connected directly. The module's circuit can operate sensors using the 2- or 3-wire technique. A microprocessor handles linearization across the whole temperature range, which is freely selectable. The EJ3214’s standard settings are: resolution 0.1°C. The signal state is indicated by light emitting diodes. Sensor malfunctions such as broken wires are indicated by error LEDs.
