Fig. 2: KL3202
The KL3201 and KL3202 analog input terminals allow 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 settings are: Resolution 0.1°C in the temperature
range of PT100 sensors in 3-wire connection.
The two Run LEDs indicate data exchange with the Bus Coupler, the error LEDs show sensor faults (e.g.
broken wire).
