Product Overview

The Honeywell 8C-PAOHA1 serves as a high-performance interface within the Experion PKS C300 I/O family. This module transmits precision analog control signals from C300 controllers to critical field instruments including control valves, actuators, and variable frequency drives (VFDs). By integrating HART protocol capabilities, the 8C-PAOHA1 facilitates bi-directional communication, allowing engineers to extract diagnostic data and configure field devices remotely without interrupting the 4-20mA control signal. We supply this module as 100% Brand New and Original in factory packaging to ensure maximum system availability in your plant.

Technical Specifications

Engineering Advantages

• Streamlined Device Management: The HART-enabled architecture eliminates the need for technicians to physically access field devices for configuration. Personnel can perform calibration and status checks directly from the Experion PKS console, reducing maintenance hours and safety risks.

• Maximum Signal Integrity: A robust 2500 VAC isolation barrier protects the C300 controller from field-side electrical noise and transient surges. This hardware-level protection ensures that ground loops do not corrupt sensitive control loops.

• Zero-Downtime Maintenance: The hot-swappable design allows you to replace a module while the system remains powered and operational. This capability proves essential for continuous processes where a shutdown results in significant production loss.

• Advanced Fault Detection: The module continuously monitors for open circuits and short circuits in the field wiring. Upon detecting a fault, the 8C-PAOHA1 automatically triggers pre-configured fail-safe states, protecting your mechanical hardware from uncontrolled movement.

• Extreme Environment Resilience: With an operating range of -40°C to +70°C, this module performs reliably in non-climate-controlled cabinets and harsh geographic locations, ensuring consistent process control regardless of external conditions.

FAQs

• Does the 8C-PAOHA1 support HART pass-through for third-party Asset Management Systems? Yes. The 8C-PAOHA1 integrates fully with Honeywell’s Asset Manager and other FDT/DTM based software, allowing seamless data flow between the field device and your maintenance management platform.

• Can I use this module with standard 4-20mA devices that do not support HART? Absolutely. The module functions as a high-precision standard analog output card. The HART digital signal sits on top of the analog signal and does not interfere with devices that lack HART capabilities.

• Is the 8C-PAOHA1 compatible with Series C I/O assemblies? The 8C-PAOHA1 belongs to the Experion C300 I/O family and requires the corresponding Series C Input/Output Termination Assembly (IOTA). Please verify your IOTA part number for compatibility.

• What is the warranty and condition of this part? We guarantee the Honeywell 8C-PAOHA1 is 100% Brand New and Original in its original factory box. We include a comprehensive 12-month warranty to ensure long-term reliability in your automation system.
