4. Product Introduction
The Honeywell CC-PAIH02 is a high-level analog input module with integrated HART capability for the Experion PKS Series C / C300 platform. It accepts up to 16 channels of voltage or current signals from field transmitters (including 2-wire loop-powered devices) and provides both the primary process variable and HART diagnostic data to the controller.
Engineers specify the CC-PAIH02 when accurate, high-density analog acquisition with smart-device support is required. The module plugs into a matching Series C IOTA, supports optional redundancy, includes open-wire detection, and supplies non-incendive field power. It remains a common spare for existing Experion installations where full migration to newer I/O families is not yet planned.
5. Installation & Configuration Guide
Stage 1: Pre-Installation Preparation (10–15 min)
⚠️ Safety First: Place the process in a safe state. Notify operations of the planned I/O outage. Lock-out/tag-out power to the Series C cabinet or IOTA. Wait for residual energy to dissipate.
Tools Required: ESD wrist strap, PH1 or equivalent screwdriver, multimeter, wire labels, smartphone for photos of existing IOTA wiring and module labeling.
Data Backup: Export or photograph the current channel configuration, HART device tags, and any open-wire or range settings in Experion. Record the exact IOTA model and slot location.
Stage 2: Removing the Old Module (5–10 min)
- Confirm the IOTA is powered down or the module is isolated.
- Release the module locking mechanism and withdraw it straight from the IOTA.
- Inspect the IOTA connectors for bent pins, corrosion, or debris.
⚠️ Keep the old module available until the new unit is online and all channels report healthy.
Stage 3: Installing the New Module (10–15 min)
- Verify the part number is CC-PAIH02 and that the conformal coating (if present) matches site requirements.
- Align the module with the IOTA guides and insert fully until the lock engages.
- Reconnect or verify field wiring on the IOTA terminals (polarity and shield grounding are critical for 4–20 mA and HART).
- Confirm any redundant partner module (if used) is correctly paired.
Self-Checklist: [ ] Module fully seated [ ] Lock engaged [ ] Field wiring verified [ ] No bent pins.
Stage 4: Power-On & Testing (15–25 min)
Pre-Power Check: Multimeter check for shorts on field power and signal terminals.
- Restore power to the IOTA/cabinet. Observe module power and status LEDs.
- In Experion, verify the module is recognized and channels come online.
- Check live values against known good transmitters; confirm HART secondary variables and diagnostics where applicable.
- Perform open-wire and over-range tests if safe to do so.
⚠️ Troubleshooting: Module not recognized usually indicates seating or IOTA mismatch. Bad PV or open-wire alarms often trace to field wiring or incorrect range configuration. HART communication failure may require verifying the 250 Ω load and loop power settings.

6. Frequently Asked Questions (FAQ)
Q: Can the CC-PAIH02 be hot-swapped?
A: Series C modules support controlled replacement under specific conditions, but best practice is to take the associated IOTA or cabinet section offline. Always follow site procedures and confirm redundancy status before removal.
Q: Is the CC-PAIH02 still in active production?
A: Honeywell continues to support the Series C family, but individual modules such as the CC- are frequently supplied from surplus or remaining authorized stock. Verify current availability and revision with the supplier.
Q: What IOTA is required?
A: Common non-redundant IOTAs include CC-TAIX01, CC-GAIX21, and CC-TAID01. Redundant pairings use CC-TAIX11, CC-GAIX11, or CC-TAID11. Match the exact IOTA to the system design and redundancy requirements.
Q: Will I lose channel configuration when I replace the module?
A: Configuration resides in the Experion database and IOTA, not permanently on the IOM. After replacement, the controller downloads the existing configuration. Always verify ranges, HART enablement, and open-wire settings after the swap.
Q: Why is the price lower than current Honeywell list pricing?
A: Many units available on the secondary market are new surplus from project overruns or authorized excess inventory. Pricing reflects that availability rather than full factory list price for current production.
Q: Does it support HART 7 or multivariable transmitters?
A: The module provides HART pass-through. Exact HART revision support and multivariable variable mapping depend on the Experion software release and transmitter capability. Confirm against the system documentation.
Q: What testing is performed before shipment?
A: Visual and coating inspection, power-on self-test, channel accuracy checks under simulated 4–20 mA / voltage inputs, and basic HART communication verification where a test rack is available. Test reports and photos are available on request.
