The KL3202 and KL3204 analog input terminals allow resistance sensors to be connected directly. The Bus
Terminal‘s circuitry can operate the sensors using 2-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 settings are: Resolution 0.1 °C in the temperature range of PT100 sensors. The error
LEDs indicate sensor faults (e.g. a broken wire). The KL3202 version combines 2 channels and the KL3204 version
combines 4 channels in one housing.

5.4.5 Bus end terminal
At the end of the periphery terminals a bus end terminal (KL9010) must be mounted, otherwise the periphery
bus coupler detects an error and no data will be send to the PLC.
