Brings high-level analog transmitter measurements and HART device information into the Series 8 control environment.
- Signal or energy path: Field-loop current enters through the matching I/O termination assembly, is converted into controller process data, and carries device-status or diagnostic information through the HART communication path.
- Companion components: Use the approved coated I/O termination assembly, transmitter wiring, loop-power arrangement and Series 8 controller infrastructure.
- Engineering check: Confirm channel allocation, grounding, shielding, transmitter power source and HART maintenance procedure against the project drawings.
- System boundary: Measurement quality depends on the selected termination assembly, loop-power source and project grounding scheme.
Pressure, flow, temperature, level and other continuous process measurements in refining, chemical, power and general process plants.
Important Notice: Verify the complete 8C-PAIHA1 51454470-275 nameplate, installed-system documentation, companion hardware and current Honeywell instructions before installation or replacement.

Important Notice: The first link is the product-parameters PDF prepared only from the cited manufacturer information; the second link is the Apter Power product manual. Confirm the physical nameplate, current manufacturer documents, and host-system requirements before installation or replacement.
4-20 mA process measurement
Acquires 16 single-ended current loops from field transmitters for continuous monitoring and control.
HART device configuration and status
Carries HART information used to configure supported field devices and read device status.
Multivariable transmitter integration
Makes supported HART secondary and tertiary variables available for process-control use in addition to the primary 4-20 mA value.
Redundant Series 8 analog input
Uses the 8C-TAIXB1 redundant IOTA where the engineered Honeywell system requires redundant I/O.
Read and follow the current Honeywell documentation and host-equipment instructions before work. Verify the complete physical nameplate and system configuration.
1
Confirm that the physical nameplate maps 51454470-275 to 8C-PAIHA1; Honeywell's reviewed public specifications do not print that material number.
2
Use 8C-TAIXA1 for a coated non-redundant configuration or 8C-TAIXB1 for a coated redundant configuration; do not mix IOTA forms without verifying the engineered system.
3
Wire only supported single-ended 4-20 mA current inputs. No differential or voltage input is supported on 8C-PAIHA1.
4
Distinguish two-wire and self-powered transmitter loops and select internal or external field power according to the approved Honeywell design.
5
The system-to-field galvanic-isolation option requires external user-supplied power according to Honeywell's note.
