3.6 Analog Input (AI) Modules
AI modules support either 16 or eight 4–20 mA or 1–5 Vdc analog
inputs.
AI modules consist of an AI PCB with either a terminal block assembly
(for local termination) or a header block assembly (for remote
termination). AI modules also include an LED board, a terminal housing
assembly, as well as I/O assembly and mounting hardware.

16 or 8
Each AI supports:
 Either 4–20mA internally sourced input
or 1–5Vdc isolated input operation.
Choice for whether the module
supports 4-20mA or 1-5Vdc is set at
the factory.
 1-5Vdc AIs have a common mode
range of 31Vdc.
 4-20mA inputs reference –VFxx of the
module.
 Analog input circuitry isolated from bus
interface.
 Surge suppression and signal
conditioning.
Cable Shields
Connect cable shields associated with AI wiring to the ControlWave
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).
