Product Description

High-Availability HART Signal Interfacing

The 8C-PAIHA1 (Model: 8C-PAIHA1) is a high-integrity analog input module specifically engineered for the Honeywell Experion PKS Series 8 hardware platform. This module serves as a high-density bridge between precision field instrumentation and the C300 controller, providing 16 dedicated channels for 4–20 mA signal acquisition. The 8C-PAIHA1 (Part Number: 51454470-275) is distinguished by its full support for HART protocol pass-through, enabling maintenance teams to extract digital device diagnostics, secondary variables, and configuration data directly from smart transmitters without interrupting the primary control loop.
