Honeywell CC-PAIX01
Product Overview: The CC-PAIX01 (part number 51405038-275) is a 16-channel high-level analog input module for Honeywell Experion PKS Series C distributed control systems. It accepts current and voltage inputs from field transmitters and sensors, converting analog signals into digital values for controller processing. The CC-PAIX01 is a non-HART module; for HART support, use CC-PAIH01 or CC-PAIH02. It has been largely superseded by the enhanced CC-PAIX02.

Difference from CC-PAIX02: The CC-PAIX01 supports differential inputs only on channels 13–16, whereas the CC-PAIX02 supports differential on all 16 channels. For new installations, CC-PAIX02 is recommended for enhanced differential input capability.
Functional Features:
- 16-bit resolution for accurate signal conversion
- Supports 4–20 mA, 0–5 V, 1–5 V, and 0.4–2 V input ranges
- Built-in diagnostics and open wire detection
- Non-incendive field power support
- Fast loop scan capability
Working Principle: Identical architecture to CC-PAIX02, with the limitation that only the upper 4 channels (13–16) benefit from differential input noise rejection. The module digitizes signals and transfers them to the C300 controller via the Series C backplane.
Application Scenarios: Legacy high-level analog input applications in Experion PKS systems; retrofit and replacement scenarios where existing system BOM specifies CC-PAIX01.
Installation & Usage Notes:
- Verify channel count (8 vs. 16) and differential capability against your specific system BOM before procurement.
- Install on a compatible Series C IOTA (non-redundant: CC-TAIX01, CC-GAIX21, CC-TAID01; redundant: CC-TAIX11, CC-GAIX11, CC-TAID11).
- Use proper shielded wiring and grounding practices.
- For new installations, consider CC-PAIX02 for enhanced differential input capability.
