2-channel analog input PT100 (RTD) EJ3202

EJ3202 | 2-channel analog input PT100 (RTD)

The EJ3202 analog input allows resistance sensors to be connected directly. The EtherCAT plug-in module's circuitry can operate 2- and 3-wire sensors. A microprocessor handles linearisation 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 EtherCAT plug-in modules indicate their signal state by means of light emitting diodes. Sensor malfunctions such as broken wires are indicated by error LEDs.
