Product Identification
8C-PAOHA1 (Part No. 51454469-275) is a high-performance analog output module with HART communication from Honeywell's Experion PKS Series 8 I/O family. It provides precise 4‑20 mA current output signals for controlling field devices such as actuators, control valves, and positioners.
The module features 16 output channels with built-in HART pass-through capability, enabling two-way digital communication with smart field devices for configuration, diagnostics, and process data retrieval. It is coated for enhanced protection in harsh industrial environments.
The 8C-PAOHA1 is compatible with C300/C200 controllers and supports redundant configurations for critical control loops requiring high availability. It includes per-channel fail-safe behavior and open-wire detection.

Functions
Signal conversion & control
- Digital-to-analog conversion — Receives digital control signals from the C300/C200 controller and converts them to precise 4‑20 mA analog outputs.
- HART pass-through — Supports HART Rev.6 protocol for bidirectional digital communication with smart field devices, enabling configuration, diagnostics, and process data retrieval.
- Multiple output ranges — Supports 4-20 mA current output with a usable range of 2.9 mA to 21.1 mA.
Diagnostics & protection
- Fail-safe behavior — Per-channel FAILOPT configuration allows HOLD LAST VALUE or SHED to SAFE VALUE on failure.
- Open-wire detection — Provides Channel Soft Failure indication for open field wiring, enabling rapid fault identification.
- Redundancy support — Optional 1:1 redundant configuration with automatic failover (switchover gap ≤ 10 ms).
Applications
The 8C-PAOHA1 is widely deployed in process and discrete control applications requiring high-precision analog output with HART capability.
Lifecycle
Active currently in production — fully supported
Product status: The 8C-PAOHA1 remains an active, supported product in Honeywell's Series 8 I/O portfolio. It continues to be the recommended analog output module with HART for new Experion PKS installations and system expansions.
Spare parts & support: Replacement units and accessories are available through Honeywell's standard support channels and authorized distributors. The Series 8 I/O family is designed for long‑term availability.
Migration & replacement:
- Native HART Rev.6 support (enhanced over earlier versions)
- Improved accuracy (±0.2% vs older modules)
- Enhanced diagnostics and fail-safe behavior
- Conformal coating for harsh environments
Recommendation: For new Experion PKS analog output applications with HART communication, the 8C-PAOHA1 remains the recommended solution.
