KL3201 | Bus Terminal, 1-channel analog input, temperature, RTD (Pt100), 16 bit
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. Linearization over the full temperature range is realized 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).
