EL3202 | 2-channel input terminal PT100 (RTD) for 2- or 3-wire connection
The EL3202 analog input terminal allows resistance sensors to be connected directly. The EtherCAT Terminal circuitry can operate 2- and 3-wire sensors. A microprocessor handles linearisation across the whole temperature range, which is freely selectable. The EtherCAT Terminal’s standard settings are: resolution 0.1 °C in the temperature range of PT100 sensors in 3-wire connection. The EtherCAT Terminals indicate their signal state by means of light emitting diodes. Sensor malfunctions such as broken wires are indicated by error LEDs.
