Honeywell CC-PAOX01
Product Overview: The CC-PAOX01 (part number 51405039-175) is a 16-channel high-level analog output (HLAO) module within Honeywell’s Experion PKS Series C I/O family. It converts digital control signals from the C300 controller into 4–20 mA analog output signals with integrated HART digital communication (HART Revision 5, 6, and 7 compatible). The module mounts directly onto the CC-TPOX01 or CC-TPOX11 I/O Termination Assembly (IOTA).

- SIL 2, ATEX, and IECEx certified
Working Principle: The module receives digital command values from the C300 controller over the Series C backplane, converts them via precision DACs into 4–20 mA current signals, and superimposes HART digital communication on the same pair. Each channel operates independently with its own fault detection and fail-safe configuration.
Application Scenarios: Driving control valves, actuators, and positioners (e.g., Fisher DVC6200, ABB I/P converters) in process industries such as oil & gas, chemical, power, and marine (LNG carriers, chemical tankers).
Installation & Usage Notes:
- Mount only on qualified CC-TPOX01 or CC-TPOX11 IOTA bases within a Series C I/O rack.
- De-energize cabinet power rails and external loop power before module insertion or removal.
- Verify controller database revision matches the module hardware revision to avoid HART communication faults.
- Maintain separation between analog output wiring and high-current AC supply lines.
- Acknowledge “Module Removal” alarm in Control Builder before hot-swapping to prevent spurious trips.
