Common pairings: Used with CC‑PAOX01 isolated analog output modules, C300 controllers, and Series C I/O racks.

Lifecycle & Replacement

Active currently in production — no planned discontinuation

Product status: CC‑PAIX01 remains an active, supported product in Honeywell's Series C I/O portfolio. It is the recommended isolated analog input module for new Experion PKS installations.

Migration & replacement considerations:

Legacy replacement path: CC‑PAIX01 is the isolated version of CC‑PAIH01, offering enhanced isolation for demanding applications. It supersedes earlier modules such as TC‑IAIH61 and 51304380‑200. Key upgrade benefits include:
  • Full 1500 VDC isolation (vs. 500 VDC in standard versions)
  • Native HART support with advanced diagnostics
  • Enhanced noise immunity for electrically harsh environments
  • Same physical footprint — drop‑in replacement with minimal system reconfiguration
Related models: CC‑PAIH01 (non‑isolated), CC‑PAOX01 (isolated analog output)

Recommendation: For applications requiring full isolation and maximum noise immunity, CC‑PAIX01 is the recommended choice.

FAQ – Frequently Asked Questions

Q1: What is the difference between CC‑PAIH01 and CC‑PAIX01?

CC‑PAIX01 provides full galvanic isolation (1500 VDC) between channels and backplane, while CC‑PAIH01 offers 500 VDC isolation. CC‑PAIX01 is recommended for electrically noisy environments or applications requiring higher isolation.

Q2: Does CC‑PAIX01 support HART communication?

Yes. It supports HART pass‑through (both Version 5 and Version 7), allowing digital communication with smart field devices via the same 4‑20 mA wiring.

Q3: Is this module hot‑swappable?

Yes. CC‑PAIX01 supports online replacement without requiring system shutdown, provided the module is in a redundant or non‑critical loop.

Q4: What diagnostics does the module provide?

It offers real‑time diagnostics including open circuit detection, over-range/under-range detection, HART communication health, and field power monitoring.

Q5: Is CC‑PAIX01 compatible with older TDC 3000 systems?

It is designed for Experion PKS Series C architecture. For TDC 3000 systems, migration to Experion PKS or use of compatible interface modules is required.
