G4I-D22C

Description

16-point DC input module variant, documented as the 24 V specific / sink-source configuration for the G4 family. Use when your installation standardizes on 24 VDC inputs.

The Polar Energy Assessment:

The D22C is a 16-point DC input module listed in LS materials as the 24 V variant. Functionally similar to D22A/D22B but intended where the plant specifies 24 V input wiring only; this avoids ambiguity for international BOMs and simplifies procurement for strictly 24 V plants. Distributor pages show it available through standard automation resellers.

Pros

• 16 channels in one slot, optimised for 24 V systems.
• Simplifies BOMs for 24 V-only installations.

Limitations

• Less flexible if site uses mixed 12/24 V loops.
• Verify sink/source convention required; D22C differs from D22B/A.

Typical use cases

• Facilities standardised on 24 VDC sensor wiring.
• Replacements in racks already populated with 24 V-only modules.
