roduct Overview

The Honeywell CC-PAOH01 (Part Number: 51405039-175) is a 16-channel Analog Output (AO) module within the Experion PKS Series C family. It drives final control elements such as valves and actuators and features integrated HART protocol support for digital communication with smart field instruments.

This module allows seamless pass-through of secondary variables and diagnostic data to asset management systems, enabling remote calibration and valve signature analysis. Its vertical Series C design optimizes airflow, extending the operational life of electronic components.

Technical Data

System Functionality and Experience

• Digital Transformation Ready: Converts digital commands into precise 4–20 mA signals while extracting HART data.

• Redundancy Options: Configurable in redundant pairs for uninterrupted valve and loop control.

• Enhanced Diagnostics: Detects open circuits or shorted wiring and reports faults to the C300 controller.

• Space Efficiency: 16-channel layout reduces the total number of I/O carriers needed.

Typical Applications

• Oil & Gas Upstream: Controls wellhead chokes and injection valves, enabling remote diagnostics for offshore sites.

• Petrochemical Processing: Manages high-speed loops for valves in distillation columns and reactor feeds.

• Steam and Power: Modulates boiler feedwater valves and steam turbine bypass systems for high reliability.

• Specialty Chemicals: Precise dosing with HART feedback confirming valve positions relative to setpoints.

FAQ

Q1: Does the CC-PAOH01 module require a separate HART multiplexer?
A1: No, each channel includes an integrated HART modem, allowing communication with smart field devices without additional hardware.

Q2: What happens to the output if the C300 controller loses communication?
A2: The module can be configured to Fail-Safe mode, holding the last value or going to a predefined safe state (e.g., 0% or 100%).

Q3: How does part number 51405039-175 differ from non-HART versions?
A3: 51405039-175 includes circuitry to overlay digital HART signals onto the 4–20 mA loop, whereas standard AO modules transmit only analog signals.

Q4: Is this module compatible with both redundant and non-redundant I/O carriers?
A4: Yes, it works in both configurations. For full hardware redundancy, a redundant I/O termination assembly and a secondary CC-PAOH01 module are required.
