25.3 Wiring topic
Two analog inputs can be wired to each of the four X1 to X4 connectors.
Two-wire configuration is supported.
When using a 2-wire configuration, the resistance value between pins 1+
and 1- will be measured and interpreted as a temperature reading. The cable
resistance will affect the reading in the form of an error. The advantage of
using this type of configuration is the fact that it requires a small number of
connection cables.
