HART Analog Output Module Honeywell 8C-PAOHA1 51454469-275

Product Description

The 8C-PAOHA1 (P/N: 51454469-275) is a specialized analog output module for the Honeywell Experion PKS Series 8 platform. It provides 16 channels of 4–20 mA current output, each supporting HART protocol pass-through, enabling bidirectional communication with smart field devices.

This module allows the C300 controller to transmit both primary analog signals and secondary diagnostic/asset data, supporting proactive maintenance and improved process reliability. Its slimline, high-density design maximizes I/O count per linear inch of DIN rail, making it ideal for cabinet-optimized installations in high-performance industrial environments.

Technical Specifications

Application Scenarios

The 8C-PAOHA1 is ideal for mission-critical control of field actuators and valves in industries such as:

• Oil & gas

• Power generation

• Chemical processing

By leveraging HART communication, operators can remotely monitor valve friction, travel time, and overall device health, reducing the need for manual field inspections.

Frequently Asked Questions

Q: How does the 8C-PAOHA1 handle hardware failures?
A: When paired in a redundant IOTA configuration, if the primary module fails, the secondary module seamlessly takes over control of the 4–20 mA loops, ensuring uninterrupted operation.

Q: What is the difference between this and a non-HART version?
A: The 8C-PAOHA1 enables digital communication with smart instruments, allowing remote calibration and detailed asset management, which standard analog output modules cannot support.
