VersaMax I/O Density and Backplane Communication
The IC200ALG266 supports analog I/O density scaling by collecting 15 current input signals within one module group. It transfers the resulting analog information through the VersaMax I/O architecture for controller processing. Therefore, the module reduces the number of separate analog input modules required for multiple 4-20 mA field loops.
The single-group channel arrangement should also be considered during system wiring. Field wiring, signal references, and shielding practices should follow the applicable VersaMax installation requirements to maintain stable current signal measurement.

Field Installation Guidelines
Install the IC200ALG266 in a compatible VersaMax I/O assembly according to the system hardware configuration.
Connect each 4-20 mA field loop to the designated analog input terminals and verify channel wiring before applying system power. In addition, keep analog signal conductors separated from high-current switching and motor power wiring.
Use appropriate shielded cable where the field installation requires noise reduction. Terminate cable shields according to the system grounding practice to avoid unwanted ground-loop currents.
Before commissioning, verify the field current range, input polarity, signal continuity, and controller configuration. Also confirm that field fault conditions remain within the specified input withstand limit.
