EL3214 | 4-channel input terminal PT100 (RTD) for 3-wire connection
The EL3214 analog input terminal allows four resistance sensors to be connected directly. The EtherCAT Terminal circuit can operate sensors using the 3-wire technique in a compact 12 mm housing. A microprocessor handles linearisation across the whole temperature range, which is freely selectable. The EtherCAT Terminal’s standard settings are: resolution 0.1 °C. Sensor malfunctions such as broken wires are indicated by error LEDs.
