KL3201 | 1-channel input terminal PT100 (RTD)
The KL3201 analog input terminal allows resistance sensors to be connected directly. The Bus Terminal’s circuitry can operate the sensors using 2-wire or 3-wire connection techniques. Linearisation over the full temperature range is realised with the aid of a microprocessor. The temperature range can be selected freely. The Bus Terminal's standard setting is: resolution 0.1 °C in the temperature range of PT100 sensors in 3-wire connection. The run LEDs give an indication of the data exchange with the Bus Coupler. The error LEDs indicate sensor faults (e.g. a broken wire).
