Honeywell CC-PAON01 51410070-175 Retrofit AO for Legacy Systems

Honeywell CC-PAON01 51410070-175 Retrofit Analog Output Module for Legacy Systems

The Honeywell CC-PAON01 (part number 51410070-175) is a high-density analog output module designed for the Honeywell Experion PKS platform, specifically engineered to interface with the C300 Controller series via the Series C I/O architecture. As manufacturing facilities worldwide face the challenge of maintaining aging distributed control systems, the CC-PAON01 has become a critical retrofit component for engineers tasked with replacing end-of-life analog output cards without triggering a full DCS migration. NINERMAS maintains verified in-stock inventory of the CC-PAON01 with pre-shipment functional testing and a 12-month warranty on every unit shipped.

The CC-PAON01 delivers 8-channel 4–20 mA analog output capability, supporting HART pass-through communication on each channel. This makes it directly compatible with smart field instruments such as control valves, positioners, and variable-speed drive references that rely on HART protocol for diagnostics and configuration. When replacing a failed or obsolete analog output card in an Experion PKS cabinet, engineers must verify the FTA (Field Termination Assembly) pairing — the CC-PAON01 is typically paired with the CC-TAON01 or CC-TAIX11 FTA depending on the field wiring configuration. Confirming the correct FTA model before ordering prevents costly rewiring during the maintenance window.

In retrofit scenarios involving older Honeywell TDC 3000 or PlantScape systems being migrated to Experion PKS, the CC-PAON01 serves as the target output module in the new I/O chassis. Engineers migrating from legacy AO modules such as the 51304485-150 or 51304485-175 analog output cards must account for differences in channel count, terminal block layout, and loop power sourcing. The CC-PAON01 operates as a non-isolated module, so field loop power must be sourced externally — a detail that directly affects how the CC-PWRR01 or CC-PWRS01 power supply modules are sized within the C300 I/O enclosure. Verifying available rail current before installing additional CC-PAON01 modules is a mandatory pre-commissioning step.

Retrofit Planning for Existing Automation Systems

A successful CC-PAON01 retrofit begins well before the maintenance window opens. The first step is a full audit of the existing I/O chassis — identifying which slots are occupied by CC-PAON01 units, which are running legacy analog output cards, and whether the chassis backplane is a standard C300 I/O Link or an extended IOLINK segment. In multi-chassis configurations, the CC-LINK01 or CC-LINK02 I/O Link modules define the communication path between the C300 Controller and the remote I/O enclosures; any firmware mismatch on these link modules can prevent a newly installed CC-PAON01 from being recognized by the controller.

Field wiring termination is the most time-sensitive task during a live system retrofit. The CC-TAON01 FTA uses a 37-pin D-sub connector to interface with the CC-PAON01 module, while field wiring connects via screw terminals on the FTA itself. Engineers replacing a failed CC-PAON01 in a running plant should pre-label all field wires against the existing loop drawings before disconnecting the FTA. In cases where the FTA is also being replaced — for example, when upgrading from an older CC-TAIX11 to a CC-TAON01 — the terminal block layout differences require careful cross-referencing of the channel-to-terminal mapping to avoid mis-wiring AO channels to incorrect field instruments.

For plants running Experion PKS R400 or earlier, the CC-PAON01 module firmware must be compatible with the Experion server software version. NINERMAS recommends confirming the Experion release level before shipment so that the correct firmware-loaded module is dispatched. In parallel, the CC-SCMB02 or CC-SCMB01 system cabinet modules and the associated CC-PWRR01 redundant power supply should be inspected for capacity headroom, as adding output channels increases the total loop current draw on the 24 VDC rail. A CC-PAON01 driving 8 active 4–20 mA loops at full scale draws approximately 160 mA of loop current from the field power bus — this must be factored into the cabinet power budget alongside other active modules such as CC-PAIN01 analog input modules and CC-PDOB01 digital output modules.

HMI configuration is another area that requires attention during a CC-PAON01 replacement. If the Experion Operator Station or the associated HMI display pages reference specific channel addresses or HART device tags, these must be verified against the replacement module’s slot assignment. A module installed in a different chassis slot than the original will require a point address update in the Experion Control Builder, and any associated HMI faceplate or trend display linked to that AO point must be re-validated before returning the loop to automatic control.

Downtime Control During System Migration

Minimizing downtime during a CC-PAON01 replacement requires a structured pre-outage preparation protocol. Before the maintenance window, engineers should place all affected AO loops in manual mode at the Experion Operator Station, record the current output values for each channel, and confirm that field devices (control valves, positioners) are in a safe hold position. This prevents process upsets when the module is physically removed from the chassis.

The CC-PAON01 supports hot-swap replacement in most Experion PKS configurations, provided the chassis firmware and Experion server version support this feature. However, NINERMAS recommends treating every CC-PAON01 swap as a cold-swap procedure unless the site has previously validated hot-swap behavior on that specific chassis revision. After installing the replacement module, the Experion Control Builder will typically detect the new module automatically and restore the channel configuration from the controller database — but engineers should manually verify each channel output value against the pre-outage record before returning loops to automatic.

For multi-module replacements — for example, replacing three CC-PAON01 units in a single maintenance window — a staged approach reduces risk. Replace one module, verify all 8 channels, return those loops to automatic, then proceed to the next module. This approach limits the number of loops in manual at any one time and reduces the risk of a process deviation caused by an operator oversight during a complex multi-loop manual period. Total elapsed time for a single CC-PAON01 swap, including pre-checks, physical replacement, and loop verification, is typically 45–90 minutes depending on the number of active HART devices on the module.

Retrofit Support FAQ

Q: Is the CC-PAON01 (51410070-175) a direct drop-in replacement for older Honeywell analog output modules?
A: The CC-PAON01 is the standard analog output module for the Honeywell Experion PKS Series C I/O platform. It replaces earlier AO cards used in TDC 3000 and PlantScape migrations, but the FTA and field wiring termination must be verified for compatibility. NINERMAS can assist with cross-referencing your existing module part number to confirm the correct replacement path.

Q: Does NINERMAS pre-test CC-PAON01 modules before shipment?
A: Yes. Every CC-PAON01 unit shipped by NINERMAS undergoes pre-shipment functional testing covering all 8 analog output channels, HART communication verification, and backplane interface checks. A test report is available upon request. All units are covered by a 12-month warranty from the date of shipment.

Q: What FTA is required for the CC-PAON01, and can I reuse my existing FTA?
A: The CC-PAON01 is compatible with the CC-TAON01 FTA. If your existing installation uses a CC-TAIX11 or an older FTA variant, a compatibility check is required before reuse. In most cases, the FTA can be retained if it is in good condition and the wiring is correctly mapped. NINERMAS recommends providing your existing FTA part number when placing an order so our technical team can confirm compatibility.

Q: What is the lead time and stock availability for the CC-PAON01 51410070-175?
A: NINERMAS maintains ready stock of the CC-PAON01 for immediate dispatch. Standard lead time is 3–7 business days for international shipments. For urgent plant breakdowns, expedited shipping is available. Contact our team at sale@ninermas.com or +0086 187 5021 5667 to confirm current stock levels and arrange priority dispatch.
