Description
Product Introduction
The Honeywell CC-PAIH02 is a Series C High-Level Analog Input Module designed for the Experion PKS Distributed Control System (DCS). It accepts voltage and current signals from field transmitters while simultaneously supporting HART communication for device diagnostics, configuration, and secondary process variables.
Compared with conventional analog input cards, the CC-PAIH02 combines fast analog acquisition with integrated HART capability. It supports optional redundant architectures, extensive onboard diagnostics, open-wire detection, and non-incendive field power, making it a common choice for refinery, petrochemical, pharmaceutical, and power generation applications.

Application Scenarios & The “Trench” Experience
A refinery experiences unstable reactor temperature readings. Operators blame the transmitter because the displayed value occasionally freezes.
Maintenance replaces the transmitter.
The problem remains.
The real fault turns out to be an analog input module that intermittently loses HART communication while still reporting a valid 4–20 mA signal. Without checking the module diagnostics, it’s easy to replace perfectly good field instruments.
Typical Applications
Oil & Gas — Process transmitters — Acquires pressure, temperature, flow, and level measurements with HART diagnostics.
Chemical Plants — Reactor control — Collects analog process variables while monitoring transmitter health.
Power Generation — Boiler instrumentation — Interfaces with smart HART transmitters for improved maintenance diagnostics.
Pharmaceutical Manufacturing — Batch processing — Supports high-accuracy analog acquisition with device status reporting.
Water & Wastewater — Pumping and treatment systems — Monitors multiple analog process variables through the Experion PKS platform.
Field Replacement Example
A hydrocracking unit repeatedly generated intermittent transmitter failure alarms on six pressure loops. Field technicians replaced two transmitters before reviewing the Experion diagnostic logs. The logs identified recurring HART communication faults originating from a single CC-PAIH02 module. After replacing the module and restoring the redundant I/O pair, every transmitter returned to normal operation without recalibration. The process interruption lasted less than one maintenance shift.

The Veteran’s Tech Trap Guide
⚠️ Don’t confuse CC- with CC-PAIX02.
The CC- supports HART communication, while the PAIX series is intended for high-level analog input without HART capability. Ordering the wrong module removes smart transmitter diagnostics.
⚠️ Verify the IOTA before ordering.
The module may be installed with several different IOTA assemblies. The module alone does not determine field wiring compatibility. Always verify the installed IOTA model.
❗ Don’t ignore open-wire diagnostics.
An open-wire alarm is frequently caused by broken field wiring or loose terminals rather than a failed transmitter. Review diagnostics before replacing field devices.
⚠️ Match firmware with the Experion release.
Most installations work without issues, but older Experion PKS revisions may require compatibility verification before introducing replacement hardware.
Frequently Asked Questions (FAQ)
Q1. What signals does the CC- accept?
The module supports 4–20 mA, 0–5 V, 1–5 V, and 0.4–2 V analog inputs while providing integrated HART communication.
Q2. How many channels are available?
The module provides 16 analog input channels, consisting of 12 single-ended inputs and 4 differential inputs.
Q3. Does it support HART communication?
Yes. The CC- communicates with HART-enabled transmitters, allowing access to configuration, diagnostics, and additional process variables without separate HART multiplexers.
Q4. Can the module be installed in a redundant system?
Yes. The Series C architecture supports redundant configurations when paired with the appropriate redundant IOTA assemblies and controller configuration.
Q5. Does it support hot swapping?
Honeywell supports online maintenance for many Series C I/O modules under specific Experion PKS configurations. However, whether a module can be replaced without interrupting the process depends on the controller redundancy, IOTA type, and plant operating procedures. Verify your site’s maintenance documentation before performing live replacement.
Q6. Why is this module less expensive than purchasing directly from the OEM?
Most available inventory originates from plant modernization projects, surplus maintenance stock, or canceled system expansions. After inspection and functional testing, these genuine Honeywell modules continue to provide a cost-effective maintenance option for existing Experion PKS installations.
Q7. What should be verified before installation?
Verify the Experion PKS software version, IOTA model, redundancy configuration, channel assignments, field wiring, HART device configuration, and the exact module part number. Also confirm compatibility with the installed carrier and controller before applying power.
