Resistance & Voltage Inputs
A - Resistance inputs, the cable arrangement doesn't matter, because the
cable used here is black (the black cable goes to R and GND).
The resistance inputs are for potential connections that are resistance based
(e.g. tanks, freezer, etc.).
B - Voltage inputs, used for user sensors. Voltage range is from 0 to 75V
(the red cable goes to U4 and U3, the black cable goes to GND).
