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