3.8 Isolated Analog Input (AI) Module
Isolated AI modules support eight 4–20 mA, 1–5 Vdc, or 0–10 Vdc
differential analog inputs.
AI modules consist of an AI PCB with two 10-point terminal block
assemblies (for local termination) or two 14-pin mass termination
headers (for remote termination), eight configuration jumpers, and a
module cover assembly. The AI PCB connects with the backplane using
a 36-pin gold-plated card-edge connector.

Each AI supports/includes:
 Jumpers to configure input for either
isolated 4–20mA, isolated 1–5 Vdc,
isolated 0–10 Vdc, or non-isolated
internally powered 4-20mA current loop
operation.
 AIs configured as isolated inputs have
a common mode range of 180V
 Analog input circuitry isolated from bus
interface
Cable Shields
Connect cable shields associated with AI wiring to the ControlWave
Micro’s housing ground. Multiple shield terminations require that you
supply a copper ground bus (up to a #4 AWG wire size) and connect it
to the housing’s ground lug.
This ground bus must accommodate a connection to a known good earth
ground (in lieu of a direct connection from the ground lug) and to all AI
cable shields. Shield wires should use an appropriate terminal lug.
Secure them to the copper bus using industry rugged hardware
(screw/bolt, lock washer, and nuts).
