EL3201-0020 | 1-channel input terminals PT100 (RTD) for 4-wire connection, high-precision, with calibration certificate
Описание
The analog input terminal EL3201-0020 enables direct connection of resistance sensors. A microprocessor handles linearisation across the whole temperature range, which is freely selectable. The EtherCAT Terminal’s standard settings are: resolution 0.01 °C in the temperature range of PT100 sensors in 4-wire connection. The EtherCAT Terminal indicates its signal state by means of light emitting diodes. Sensor malfunctions such as broken wires are indicated by error LEDs. The EL3201-0020 has a precision of 0.1 °C at 40 °C ambient temperature. The terminal can also be operated with 2- or 3-wire connection and with other sensors than PT100. The maximum accuracy is achieved in 4-wire operation with PT100 sensors.
