Chapter 6: CONNECTOR PIN ASSIGNMENTS
Isolated inputs, digital inputs and relay outputs are connected to the board via a 50-pin HEADER type connector
P1. The mating connector is an IDC type with 0.1 inch centers or equivalent. The wiring may be directly from the
signal sources or may be on ribbon cable from screw terminal accessory boards. Pin assignments follow.
