The EJ3202 EtherCAT plug-in module allows resistance sensors to be connected directly. The module's circuitry can operate 2- and 3-wire sensors. A microprocessor handles linearization across the whole temperature range, which is freely selectable. The EJ3202’s standard settings are: resolution 0.1°C in the temperature range of Pt100 sensors in 3-wire connection. The signal state is indicated by light emitting diodes. Sensor malfunctions such as broken wires are indicated by error LEDs.
