Resistance input
The resistance inputs are always passive inputs. The controller sends a small current through the external equipment and measures
the resistance.
INFO
Note that there is no software compensation for the wire length to the resistance input. Errors due to wire length can be
adjusted by creating a custom graph for the analogue input in PICUS.
