The Honeywell CC-PAOH01, part number 51405039-176, is a high-performance Analog Output (AO) module with HART (Highway Addressable Remote Transducer) capability, designed for the Experion PKS C300 controller system. This “Series C” module provides 16 isolated channels to drive field actuators, such as control valves and positioners, using a 4-20 mA signal. The integrated HART functionality allows for bidirectional digital communication with smart field devices, enabling remote configuration, advanced diagnostics, and instrument health monitoring directly from the control room.

Applications
The CC-PAOH01 is a critical component in process automation industries including oil and gas, chemical refining, and power generation. It is specifically used where precise control of final control elements is required. Because it supports HART, it is the preferred choice for “smart” plants that utilize predictive maintenance. Engineers can monitor valve travel, friction, and internal diagnostics without needing to visit the field, significantly reducing downtime and maintenance costs in hazardous environments.
Operating Instructions
The CC-PAOH01 module must be installed onto a compatible Series C I/O Termination Assembly (IOTA), such as the CC-TAOX01 (non-redundant) or CC-TAOX11 (redundant). Before mounting, ensure the IOTA is properly grounded and the carrier power is within the specified 24 VDC range. Align the module connectors with the IOTA headers and push firmly until the locking tabs click into place. In the Experion PKS Configuration Studio, the module should be added to the C300 controller I/O tree, and the HART pass-through feature should be enabled to allow the Asset Management System (AMS) to communicate with the field devices.
Frequently Asked Questions
Q: Does this module support redundant configurations? A: Yes. When used with a redundant IOTA (CC-TAOX11) and a pair of CC-PAOH01 modules, the system supports seamless failover. If the primary module fails, the secondary module takes over the 4-20 mA output without any disruption to the process.
Q: Can the CC-PAOH01 drive high-impedance loads? A: The module is designed to drive standard industrial loads up to 750 ohms at 20 mA. For loads exceeding this, ensure the field power supply is sufficient to overcome the total loop resistance including the cable run.
Q: How do I access the HART data from this module? A: HART data is accessed through the Experion PKS system. The module strips the digital HART signal from the 4-20 mA analog carrier and routes it through the C300 controller to the server, where it can be viewed in the instrument’s faceplate or in specialized asset management software.
