All sensors must be connected to the inputs at the top of controller’s input Interconnect board. There are six
terminal strips for inputs. Four (4) strips are for analog inputs (1 through 14) and the other two (2) are for digital
inputs (1 through 6).
Input numbers are labeled on the interconnection board and 1 is to the left for both analog and digital terminals.
Some analog input terminals, (1, 2, 4 and 5) have a 12V output that is required by certain sensors. All digital inputs
have the 12V output available.
