G4I-A22A

Description

A 16-point AC input module variant rated for 200–240 VAC (50/60 Hz), covering higher voltage AC sensing needs on LS G4 PLC racks.

The Polar Energy Assessment:

Functionally the sibling of the A12A, the G4I-A22A swaps the input voltage rating up to the 200–240 VAC range for regions or equipment that use higher AC auxiliary voltages. It preserves the same 16-point density and LS G4 electrical form factor so you can swap based on your line voltage without changing wiring practices beyond ensuring correct nominal voltage.

Pros

• Same 16-point density as the 110 VAC module, but for 220 VAC systems.
• Reduces need for voltage conversion or external relays when sensing higher AC lines.
• Well documented in LS product literature.

Limitations

• Not interchangeable with 110 VAC modules unless wiring and BOM are updated.
• Higher voltage sensing requires careful safety wiring and suppression components.

Typical use cases

• Control racks that interface directly to 220 VAC sensor/indicator circuits.
• Regions where 220 VAC is the plant standard.
• Replacement or spares inventory for G4 PLCs in higher-voltage installations.
