Honeywell CC-PAON01 Analog Output Module

Description

Product Introduction & Engineering Value

The CC-PAON01 is a field-facing analog-output module used when the control strategy needs to command real-world equipment through standard 4–20 mA signals. Typical loads include actuators and recording or indicating devices. Honeywell specifies it as a 16-channel, non-HART analog output module in the Series C I/O family.

For replacement work, the IOTA configuration matters just as much as the IOM itself. Honeywell documents CC-TAON01 for non-redundant installations and CC-TAON11 for redundant installations. The module is also supported by Honeywell’s Universal Marshalling Solution.

Technical Specifications

These values come from Honeywell’s Series-C I/O specification.

The module also provides per-channel FAILOPT behavior, allowing configuration for either holding the last value or shedding to a defined safe value. If the IOM electronics itself fails, Honeywell specifies the output as going to zero, the defined safe state.

Field Application & the “Trench” Experience

A process unit was running an older Experion installation controlling several modulating valves. One output channel began producing an unstable control signal. The valve positioner and field wiring checked out, but the corresponding DCS output continued to generate diagnostic discrepancies.

Instead of immediately replacing the C300 controller, the maintenance team isolated the affected I/O channel and checked the Series C module. Output readback and field-loop measurements pointed toward the analog-output module. Replacing the CC-PAON01 and validating the output against a calibrated loop instrument restored the valve-control signal.

The important point: a single bad AO channel does not automatically mean the controller is failing.

Practical applications include:

• Control-valve position commands in continuous process units
• Variable-speed drive speed references using 4–20 mA interfaces
• Damper and actuator control in process utility systems
• Chemical dosing control where analog output drives a metering device
• Furnace or boiler control loops requiring analog manipulation of fuel or air-control equipment

Transparency SOP: QA & Testing

For New Surplus or Refurbished CC-PAON01 inventory, a meaningful QA sequence should include:

1. Part-number verification — Confirm CC-PAON01, revision, labeling, and physical identification.
2. IOM inspection — Examine the connector, PCB, housing, keying features, and visible components.
3. Power-up test — Verify normal module initialization using an appropriate Series C test environment.
4. Channel test — Exercise representative analog-output channels across the specified current range.
5. Readback verification — Compare commanded output against measured/readback current.
6. Open-wire diagnostics — Where the test setup permits, verify detection and reporting of an open field circuit.
7. Redundancy test — For units intended for redundant service, test with the appropriate CC-TAON11 configuration.
8. Final QA record — Record serial information, condition, test results, and configuration.

A module that simply powers up should not be represented as fully function-tested.

The Veteran’s Tech Trap Guide

⚠️ Do not confuse CC-PAON01 with CC-PAOH01.

Honeywell identifies CC-PAON01 as a non-HART analog output module, while CC-PAOH01 is the HART analog-output variant. If the application requires HART communication, the suffix matters.

⚠️ Do not ignore the IOTA.

The standard Series C configuration uses CC-TAON01 for non-redundant installations and CC-TAON11 for redundant installations. The IOM and termination assembly must be treated as a matched system.

PRO TIP: Before removing the module, record every channel assignment and measure several known-good output channels. This gives you a baseline for commissioning the replacement.

⚠️ Check the load before blaming the IOM.

The specified maximum resistive load is 800 Ω under the stated 24 V supply conditions. Long cable runs, isolators, positioners, and other loop devices can consume voltage headroom.

⚠️ Lifecycle status deserves attention.

Honeywell’s May 2026 System Hints newsletter lists CC-PAON01 as the recommended replacement for CC-PAOX01 in the lifecycle table, while CC-PAON01 itself remains identified as a Series C I/O component. This distinction is important when planning a migration rather than simply replacing a failed module.

Dynamic FAQ

Q1. What is the Honeywell CC-PAON01?

The CC-PAON01 is a 16-channel high-level analog-output module for Honeywell Experion Series C I/O systems. It provides standard 4–20 mA outputs to field devices.

Q2. Is CC-PAON01 a HART module?

No. Honeywell’s module summary identifies CC-PAON01 as 16-point analog output without HART. HART-capable variants include CC-PAOH01 and CC-PAOH51.

Q3. How many analog outputs does CC-PAON01 provide?

It provides 16 analog-output channels, with a 4–20 mA output type.

Q4. What IOTA should be used with CC-PAON01?

Honeywell specifies CC-TAON01 for non-redundant installations and CC-TAON11 for redundant installations.

Q5. Does CC-PAON01 support output diagnostics?

Yes. The module supports output readback and discrepancy alarms, as well as open-wire detection. Honeywell also provides configurable per-channel FAILOPT behavior.

Q6. How should New Surplus CC-PAON01 inventory be verified?

Check the OEM identification, module revision, connector/keying configuration, and physical condition. For functional verification, test multiple 4–20 mA channels and, where possible, confirm output readback and diagnostic behavior using a compatible Series C test setup.

Warranty: Warranty terms depend on the supplier and stock condition. For refurbished CC-PAON01 units, request documented channel-level testing and written functional warranty coverage before purchase.
