Honeywell 8C-PAOH51 51454355-175 HART Analog Output Module

Product Description

The 8C-PAOH51 (P/N: 51454355-175) is a high-performance analog output module designed for the Honeywell C300 controller and Experion PKS Series 8 platform. It provides 16 channels of precision current output, enabling accurate control of final control elements such as valves, actuators, and variable-speed drives.

Supporting HART protocol pass-through, the module allows digital diagnostics from smart field devices to be transmitted back to the control system. This facilitates proactive maintenance, improves process uptime, and enhances safety. Its slim Series 8 form factor is optimized for vertical mounting, reducing cabinet footprint while maintaining robust thermal performance.

Technical Specifications

Application Scenarios

The 8C-PAOH51 is widely used in process industries, including:

• Chemical refining

• Pharmaceutical production

It is typically deployed to drive control valves, providing both position control and HART-based diagnostic feedback to maintain safety and process efficiency.

Frequently Asked Questions

Q: Does the 8C-PAOH51 support redundant configurations?
A: Yes. When installed on a redundant I/O Termination Assembly (IOTA), two 8C-PAOH51 modules can operate as a redundant pair, ensuring continuous control loop operation in case of a single module failure.

Q: Can this module be used for 0–10 V output signals?
A: No. The 8C-PAOH51 is specifically designed for 4–20 mA current loops. Voltage output applications require a different module variant.
