4.4 Additive Meters and Digital Inputs
The A4I module provides 10 inputs that can be used for either additive meter pulse inputs or as DC digital
inputs and 20 AC digital outputs. The AC digital outputs are wired using the same method shown for the
A4M and A4B modules. However, the meter pulse and DC digital inputs are wired differently on the A4I
module, as illustrated in the following diagrams.
