Description
Product Introduction & Engineering Value
When a critical transmitter stops reporting, operators need both the process value and the instrument diagnostic. The CC-PAIH01 delivers both: it converts 4–20 mA or selected voltage signals into 16-bit digital data for the C300 controller while maintaining HART communication with the field device.
It supports open-wire detection, extensive self-diagnostics, non-incendive field power, and optional redundancy. That combination makes it a common choice for pressure, flow, level, and temperature transmitters in Experion PKS installations.

Field Application & The “Trench” Experience
A unit operator reported a drifting level indication on a deaerator storage tank. The field transmitter still showed a valid 4–20 mA loop, but the DCS value was noisy and intermittently bad. The technician used the CC-PAIH01 HART interface to read the transmitter’s secondary variables and identify a saturated impulse line rather than replacing the module immediately. After the impulse line was cleared, the analog input and HART diagnostics returned to normal—avoiding an unnecessary module change.
Typical applications include:
- Pressure, flow, level, and temperature transmitter acquisition
- Multivariable HART instruments requiring secondary and tertiary process variables
- Experion PKS C300 I/O upgrades and brownfield transmitter integrations
- Critical analog loops where open-wire detection and module redundancy are required

Transparency SOP: QA & Testing
- Identity check: Confirm CC-PAIH01, material number 51405038-175, and Series C HART analog-input configuration.
- Visual inspection: Inspect module guides, backplane connectors, status LEDs, and PCB for corrosion, cracked solder, or heat damage.
- Backplane test: Verify proper seating and communication with the Series C IOTA and C300 controller.
- Analog calibration check: Apply traceable 4–20 mA and voltage test signals; verify scaling, resolution, and repeatability.
- HART verification: Confirm HART communication, device identification, primary/secondary variable access, and diagnostic reporting.
- Diagnostic test: Validate open-wire detection and fault/alarm behavior where test capability permits.
- Redundancy check: For redundant installations, verify paired-module operation and failover configuration.
- Traceability: Record calibration results, firmware/configuration, test data, and condition grade before shipment.
The Veteran’s Tech Trap Guide
⚠️ Voltage inputs are not available on every channel. With the standard IOTA, CC-PAIH01 supports voltage inputs only on channels 13–16. Channels 1–12 are current-input channels; attempting to configure voltage on the wrong channel will not work.
⚠️ CC-PAIH01 is superseded. Honeywell identifies CC-PAIH02 as the replacement. If you are expanding or rebuilding I/O, verify whether the existing IOTA and project configuration support the newer module before ordering.
PRO TIP: Before replacing the module, use HART to check the transmitter itself. A plugged impulse line, saturated transmitter, poor loop power, or grounding issue can mimic an AI-module fault.
⚠️ Do not mix up CC-PAIH01 and CC-PAIH02 channel behavior. CC-PAIH02 supports voltage inputs on all 16 channels when used with the appropriate CC-TAIDx1 IOTA, whereas CC-PAIH01 supports voltage only on channels 13–16.
