Honeywell 8C-PAIH51 Analog Input 51454352-175 | USA Made

Honeywell 8C-PAIH51 51454352-175 Experion Series 8 Analog Input Module

Product Description

The 8C-PAIH51 (51454352-175) is a high-density analog input module belonging to Honeywell’s Series 8 I/O family, engineered specifically for the Experion Process Knowledge System (PKS). Designed to interface with the C300 controller platform, this module provides 16 differential channels for the precise acquisition of 4–20 mA current signals from field transmitters, pressure sensors, and flow meters.

As a critical component of a Distributed Control System (DCS), the 8C-PAIH51 (51454352-175) features an advanced 16-bit Sigma-Delta analog-to-digital converter to ensure high-fidelity signal reproduction for process control loops. The module is built with an industrial-hardened design, including G3 conformal coating as standard, making it suitable for deployment in corrosive or harsh environments such as chemical refineries and offshore platforms. Its integration into Honeywell’s Fault Tolerant Ethernet (FTE) architecture allows for seamless redundancy and high system availability.
