Product Overview

Honeywell CC-PAOH01 51405039-175 Replacement for Experion PKS C300: Seamless Migration & Upgrade Solution

The Honeywell CC-PAOH01 (part number 51405039-175) is an 8-channel analog output module designed for the Experion PKS C300 Series Distributed Control System. As legacy DCS installations age and original spare parts become increasingly difficult to source, facilities running Honeywell TDC 3000, PlantScape, or early-generation Experion PKS platforms face mounting pressure to modernize their I/O infrastructure without triggering a full system shutdown. This listing provides a verified replacement and upgrade solution for the CC-PAOH01 module, engineered to support smooth migration with minimal disruption to ongoing production.

The CC-PAOH01 delivers 8 channels of 4–20 mA analog output, interfacing directly with the C300 Controller via the Series C I/O Link. Each channel supports HART pass-through communication, enabling field device diagnostics and configuration without rewiring. The module mounts on a standard FTA (Field Termination Assembly) backplane, sharing the same physical footprint and connector pinout as its predecessor modules in the Experion PKS architecture. This means that during a retrofit or emergency replacement, existing field wiring, marshalling cabinets, and FTA assemblies can be retained without modification — a critical advantage when minimizing downtime is the primary objective.

When migrating from a TDC 3000 or PlantScape environment, engineers frequently encounter compatibility challenges across the I/O bus, controller firmware, and FTA wiring schemes. The CC-PAOH01 resolves these challenges by conforming to the Experion PKS Series C I/O specification, which is backward-compatible with C200 and C300 controller platforms. Facilities upgrading from the older MC-PAOY22 or MC-PAOY44 analog output modules will find that the CC-PAOH01 maintains equivalent channel density while adding HART capability and improved diagnostics — without requiring changes to the control cabinet layout or DIN rail mounting configuration.

A complete migration typically involves coordinating several interdependent components. The CC-PAOH01 operates in conjunction with the CC-TAOX11 or CC-TAOX51 FTA (Field Termination Assembly), which provides the physical terminal blocks for field wiring. The C300 Controller (CC-PCF901) manages the I/O Link and must be running compatible firmware to recognize the module. Power distribution within the cabinet is handled by the CC-PWR001 or CC-PWR002 power supply modules, which provide the 24 VDC rail required by the Series C I/O chassis. For installations requiring extended I/O capacity, the CC-SCMB01 Series C I/O Link extender allows additional I/O modules to be distributed across remote cabinets while maintaining a single logical I/O Link segment.

Communication protocol compatibility is a key consideration in any DCS migration. The CC-PAOH01 communicates over the proprietary Experion PKS I/O Link, which is distinct from Modbus, PROFIBUS, or FOUNDATION Fieldbus. However, HART-enabled field instruments connected to the module’s output channels can be accessed through the Experion PKS HART Multiplexer or via the FDM (Field Device Manager) software, preserving existing HART asset management workflows. Facilities that have deployed Honeywell’s OneWireless network for field device monitoring can continue to leverage that infrastructure alongside the CC-PAOH01 without protocol conflicts.

For sites performing a phased migration — replacing modules one at a time while the system remains online — the CC-PAOH01 supports hot-swap replacement when the C300 controller is configured for redundant I/O operation. This allows maintenance teams to swap the module during a scheduled maintenance window without taking the associated control loop offline. The replacement procedure involves removing the faulty module from the Series C I/O chassis, inserting the new CC-PAOH01, and allowing the C300 controller to automatically download the module configuration from its resident database. No manual re-parameterization is required if the original module configuration has been preserved in the Experion PKS Control Builder project.

Physical installation is straightforward: the CC-PAOH01 occupies a single slot in the Series C I/O chassis (CC-SCMB01 or equivalent), with the FTA cable connecting to the corresponding FTA mounted in the marshalling cabinet. The module draws power from the chassis backplane and does not require a separate power connection. Its compact form factor is compatible with both standard 19-inch rack enclosures and custom control cabinet configurations commonly found in refinery, petrochemical, and power generation applications.

From a procurement standpoint, sourcing a verified CC-PAOH01 replacement is often the fastest path to restoring system availability after an unplanned module failure. Our inventory is tested prior to shipment, and each unit is accompanied by documentation confirming functional verification. We maintain stock of related components including the CC-TAOX11 FTA, CC-PCF901 C300 Controller, and CC-PWR001 power supply to support complete kit orders for planned maintenance outages. Orders are processed within 1–2 business days, with express shipping options available for emergency requirements. All units are covered by a 12-month warranty from the date of shipment.

Seamless Upgrade Solutions

A successful CC-PAOH01 migration rarely involves a single module in isolation. In practice, the replacement is part of a broader I/O modernization effort that touches multiple components within the same control cabinet or I/O chassis. The CC-TAOX11 Field Termination Assembly provides the wiring interface between the CC-PAOH01 and field instruments, and must be present for the module to function. Where higher channel density is required, the CC-PAIX02 8-channel analog input module is commonly deployed alongside the CC-PAOH01 to complete a balanced I/O upgrade within the same chassis slot allocation.

Controller-level upgrades often accompany I/O modernization. The CC-PCF901 C300 Process Controller is the primary controller compatible with the CC-PAOH01 and supports redundant controller configurations for high-availability applications. For sites still operating on C200 hardware, the CC-PCF901 represents a direct upgrade path that preserves existing Series C I/O investments. Power infrastructure upgrades typically involve the CC-PWR001 or CC-PWR002 chassis power supply modules, which must be sized to support the additional current draw of expanded I/O configurations.

Communication infrastructure upgrades may also be required. The CC-SCMB01 Series C I/O Link extender supports remote I/O placement up to 100 meters from the controller cabinet, enabling flexible cabinet layouts in large process units. For facilities integrating Honeywell’s Safety Manager or Safety Manager SC into the same control architecture, the CC-PAOH01 can coexist within the same Experion PKS network without protocol conflicts, provided the safety I/O is segregated onto dedicated FTA assemblies. Additionally, the Honeywell FDM (Field Device Manager) software module enables centralized HART device management across all CC-PAOH01 channels, reducing the need for handheld HART communicators during commissioning and routine maintenance.

Retrofit Guidance FAQ

Q: Can I reuse existing field wiring when replacing an MC-PAOY22 with a CC-PAOH01?
A: Field wiring to the terminal blocks is retained at the FTA level. However, the FTA itself must be upgraded from the legacy MC-series FTA to the CC-TAOX11 or CC-TAOX51, as the connector interface between the module and FTA changed between generations. Field cables connecting the FTA to junction boxes or marshalling panels do not require modification.

Q: Does the CC-PAOH01 require firmware updates on the C300 Controller?
A: The CC-PAOH01 is supported by C300 firmware R500 and later. Sites running earlier firmware versions should schedule a controller firmware update prior to module replacement. The update can be performed online without a controller restart in most configurations.

Q: How is the module configured after installation?
A: Module configuration is managed through Honeywell Control Builder. If the original module’s configuration is preserved in the project database, the C300 controller will automatically push the configuration to the replacement CC-PAOH01 upon detection. No manual channel parameterization is required in standard replacement scenarios.

Q: Is the CC-PAOH01 compatible with PROFIBUS or Modbus field devices?
A: The CC-PAOH01 outputs standard 4–20 mA analog signals and supports HART protocol for digital communication with HART-enabled field devices. It does not natively support PROFIBUS or Modbus at the module level. Protocol conversion for PROFIBUS or Modbus devices is handled at the controller or gateway level within the Experion PKS architecture.

Q: Can the module be installed in a cabinet with limited space?
A: The CC-PAOH01 occupies a single slot in the Series C I/O chassis, which has a standard 19-inch rack form factor. The associated CC-TAOX11 FTA mounts separately in the marshalling cabinet. The compact design allows high channel density (8 outputs per slot) compared to legacy modules, often reducing the total number of chassis slots required and freeing cabinet space.
