Honeywell CC-PAOX01 | 16-Channel HLAO HART Module | Series C

Honeywell CC-PAOX01 High Level Analog Output Module (HART)

The Honeywell CC-PAOX01 provides 16 channels of High-Level Analog Output (HLAO) with integrated Highway Addressable Remote Transducer (HART) digital communication. This Series C module functions as the primary interface between the Experion PKS controller and field actuators like Fisher DVC6200 positioners or ABB I/P converters. It mounts directly onto the CC-TPOX01 or CC-TPOX11 I/O Termination Assembly (IOTA). The module executes 4-20mA signal delivery while simultaneously extracting secondary HART variables for asset management systems.

In marine propulsion and auxiliary control, the Series C architecture of the CC-PAOX01 minimizes the physical footprint within congested ECR (Engine Control Room) cabinets. The 24V DC field-powered design maintains loop integrity over long cable runs, negating signal attenuation between the automation bridge and the machinery space. For ETOs managing chemical tankers or LNG carriers, this module is the standard for localized high-density I/O where galvanic isolation of 1500V DC is a non-negotiable safety requirement.

Where to Use – Applications:

Technical Maintenance Schedule by NDMarineTech

• Use a calibrated 1.5Nm-rated precision torque driver to tighten all of the IOTA terminal’s screws to 0.5Nm. This will protect them from coming free when they shake.
• Use a 10x LED jeweler’s loupe to look at the 20-pin Hirose connector pins and see if any of the contacts are bent or discolored.
  When in “Source” mode, use a Fluke 789 Process Meter to check that the loop current is correct on all 16 channels.
• Use a lint-free, anti-static cloth that has been dampened with 99% isopropyl alcohol to clean the gold-finger contacts on the Series C backplane.
• Use the Honeywell Experion Control Builder suite to save the current settings and firmware versions for the HART device and module.
• To keep the Class 1.0 signal accuracy, calibrate the analog output DAC (digital-to-analog converter) every two years.
• Unplug the CC-PAOX01 and use a Megger at 250VDC to check the insulation on the field wire to determine if the cable jacket is breaking down.
