2-Channel PT100 (RTD)
Input Terminal
The KL3202 analog input terminal permits direct connection of two resistance sensors. The
bus terminal circuit is capable of operating 2 and 3-wire sensors. Linearisation of the
entire temperature range is realised by a microprocessor. The temperature range can be
chosen freely. The standard setting of the bus terminal is 0.1°C resolution in the
temperature range of the PT100 sensor, 3-wire connection. The RUN LEDs indicates
operability and the logical connection to the bus coupler. The Error LEDs indicates sensor
malfunctions (i.e. wire breakage).
