Honeywell CC-TAOX01 Replacement for Experion PKS C300

Product Overview

Honeywell CC-TAOX01 Replacement for Experion PKS C300 — Seamless DCS Migration & Upgrade Solution

The Honeywell CC-TAOX01 (P/N 51308351-175) is an 8-channel analog output module designed for the Experion PKS C300 DCS platform. As legacy DCS installations age and original spare parts become increasingly difficult to source, plant engineers and procurement teams face mounting pressure to maintain uptime while managing obsolescence risk. This replacement and upgrade solution is engineered to address exactly that challenge — delivering a drop-in compatible module that integrates directly into existing C300 controller architectures without requiring changes to field wiring, control strategies, or cabinet layouts.

Whether you are replacing a failed CC-TAOX01 in a running process plant, building a spare parts inventory ahead of a planned shutdown, or executing a phased DCS modernization project, this module provides the signal integrity, channel density, and protocol compatibility your system demands. The CC-TAOX01 outputs 4–20 mA analog signals across 8 independent channels, interfacing with the C300 controller via the standard FOUNDATION Fieldbus H1 or FIM (Field Interface Module) backplane architecture used throughout the Experion PKS system.

In a typical Experion PKS installation, the CC-TAOX01 is mounted on a CC-PCNT01 or CC-PCNT02 I/O Link termination carrier, which provides the physical backplane connection and field terminal interface. During replacement, the termination carrier remains in place — only the module itself is swapped, preserving all field wiring connections and eliminating the need for re-termination. This design significantly reduces the risk of wiring errors and cuts replacement time to under 30 minutes in most cases.

For sites running mixed I/O configurations, the CC-TAOX01 coexists on the same I/O Link segment with analog input modules such as the CC-TAIM01 (51308351-150) and digital output modules like the CC-TDOB01 (51308351-275), all sharing the same carrier and cabinet footprint. This modular architecture means that a partial cabinet upgrade — replacing only the analog output modules while retaining existing AI and DI modules — is fully supported without any system reconfiguration.

Communication between the C300 controller and its I/O subsystem relies on the proprietary Honeywell FTE (Fault Tolerant Ethernet) network, which remains fully intact during a module-level replacement. No changes to the FTE switch configuration, IP addressing, or controller redundancy settings are required. Sites using CC-PCNT01 redundant I/O Link controllers will find that the replacement module is automatically recognized by the redundant partner upon insertion, with bumpless transfer maintaining process output continuity.

For plants considering a broader migration from older Honeywell TDC 3000 or PlantScape systems to Experion PKS, the CC-TAOX01 represents a key building block in the new I/O architecture. Legacy HPM (High-Performance Process Manager) analog output cards and FTA (Field Termination Assembly) panels can be mapped to equivalent Experion PKS I/O modules during the migration, with the C300 controller and its associated CC-TAOX01 modules handling the same process variables previously managed by the HPM. This migration path is well-documented in Honeywell’s system migration guides and is supported by the standard Experion PKS engineering tools.

Power supply compatibility is another critical consideration during replacement. The CC-TAOX01 draws its operating power from the I/O Link carrier, which is in turn powered by the cabinet’s 24 VDC bulk power supply — typically a CC-PWR001 or equivalent Honeywell-approved power module. No additional power wiring is required for the module itself. Field loop power for the 4–20 mA output circuits is sourced from the field device side, consistent with standard two-wire transmitter and valve positioner wiring practices.

Physical installation dimensions are identical to all standard C300 I/O modules, ensuring that the CC-TAOX01 fits into any existing C300 I/O cabinet without modification. Cabinet space planning for new installations should account for the standard module height and the carrier rail spacing defined in the Experion PKS hardware installation guide. For sites with constrained cabinet space, the 8-channel density of the CC-TAOX01 offers a favorable channel-per-slot ratio compared to older 4-channel analog output cards from legacy systems.

During commissioning and loop checkout, the CC-TAOX01 supports forced output and diagnostic functions accessible through the Experion PKS Control Builder engineering workstation. Channel-level diagnostics, including open-loop detection and output saturation alarms, are available without additional hardware. For sites using Honeywell’s Asset Management System (AMS) or third-party HART pass-through tools, the module’s analog outputs are compatible with HART-enabled field devices, allowing device configuration and diagnostics to be performed over the 4–20 mA loop.

Seamless Upgrade Solutions

A successful CC-TAOX01 replacement or DCS migration project rarely involves a single module in isolation. In practice, plant engineers sourcing a replacement CC-TAOX01 are often simultaneously evaluating the condition of adjacent I/O modules on the same carrier. The CC-TAIM01 (51308351-150) analog input module and the CC-TDOB01 (51308351-275) digital output module share the same I/O Link segment and carrier infrastructure, making them natural candidates for concurrent inspection or proactive replacement during a planned outage.

For sites upgrading from TDC 3000 or PlantScape to Experion PKS, the migration typically involves replacing legacy HPM analog output cards and their associated FTA panels with C300 I/O modules and CC-PCNT01 carriers. The C300 controller module itself — along with its redundant partner — forms the backbone of the new architecture, and ensuring that the controller firmware is current before installing replacement I/O modules is a recommended pre-commissioning step.

Communication infrastructure upgrades often accompany I/O module replacements. Sites running older Honeywell Data Hiway or LCN (Local Control Network) segments may be migrating those process areas to FTE simultaneously, requiring new FTE switches and FIM modules to be installed alongside the replacement CC-TAOX01 units. The Experion PKS Server and its associated ACE (Application Control Environment) nodes should also be verified for compatibility with the current module firmware revision before deployment.

For field device integration, sites using HART-enabled valve positioners or smart transmitters on the analog output loops will benefit from verifying HART revision compatibility between the CC-TAOX01 and the connected field devices. A HART communicator or handheld device configurator is a standard commissioning tool for this verification step. Signal isolators may be required in installations where ground loop issues or long cable runs introduce noise on the 4–20 mA circuits.

Finally, for sites building a comprehensive spare parts strategy, stocking a CC-TAOX01 replacement module alongside a spare CC-PCNT01 I/O Link controller and a spare 24 VDC power supply module provides a complete recovery kit for the most common C300 I/O cabinet failure scenarios, minimizing mean time to repair (MTTR) and protecting against extended production losses.

Retrofit Guidance FAQ

Q: Can I replace the CC-TAOX01 without re-terminating field wiring?
A: Yes. The module plugs into the CC-PCNT01 or CC-PCNT02 termination carrier, which retains all field wiring. Only the module is swapped; no field re-termination is required.

Q: Is the replacement module compatible with my existing C300 controller firmware?
A: The CC-TAOX01 is compatible with all standard Experion PKS C300 firmware revisions. It is recommended to verify the module hardware revision against the system’s qualified hardware list (QHL) before installation.

Q: Will replacing the CC-TAOX01 interrupt process outputs?
A: On systems with redundant I/O Link controllers (CC-PCNT01 redundant pair), the redundant partner maintains outputs during module replacement, enabling bumpless transfer. On non-redundant configurations, outputs will be interrupted during the swap.

Q: Does the CC-TAOX01 support HART communication?
A: Yes. The module supports HART pass-through on all 8 analog output channels, allowing HART-enabled field devices to be configured and diagnosed over the 4–20 mA loop using a HART communicator or the Experion AMS.

Q: What are the physical installation requirements?
A: The CC-TAOX01 occupies a standard C300 I/O module slot on the CC-PCNT01 or CC-PCNT02 carrier. No cabinet modification is required. The module is powered via the carrier backplane from the cabinet’s 24 VDC supply.

Q: Can this module be used in a migration from TDC 3000 or PlantScape?
A: Yes. The CC-TAOX01 is a standard component in Honeywell’s recommended migration path from TDC 3000 HPM and PlantScape systems to Experion PKS C300. Process variables previously handled by HPM analog output cards are mapped to CC-TAOX01 channels in the new architecture.
