8C-PAIM01 | Honeywell Experion PKS Series 8 | 51454358-175 | Analog Input Module

Description

The 8C-PAIM01 (P/N 51454358-175) is a high-density Analog Input (AI) module specifically engineered for the Honeywell Experion PKS Series 8 platform. This module serves as a high-precision interface for measuring process variables such as pressure, temperature, flow, and level. It is designed to convert field signals into digital data for processing by the C300 controller. Unlike standard AI modules, the 8C-PAIM01 is optimized for high-reliability data acquisition with advanced filtering to mitigate electromagnetic interference (EMI) commonly found in industrial switchrooms.

System Implementation and Diagnostics

Integration of the 8C-PAIM01 (51454358-175) into the Series 8 environment is facilitated through the Input/Output Termination Assembly (IOTA). The module supports "Hot Swap" functionality, allowing for live replacement without disrupting the power or communication to adjacent modules. Diagnostic features include open-wire detection, out-of-range alarms, and internal module self-tests, which are reported in real-time to the Experion system status display to minimize troubleshooting time.

Frequently Asked Questions

Does the 8C-PAIM01 support HART digital communication?No, the 8C-PAIM01 is a high-level analog input module focused on pure signal acquisition. For applications requiring HART protocol pass-through to FDM (Field Device Manager), the HART-enabled variant (e.g., 8C-PAIH01) should be utilized.

Can this module be used in a redundant configuration?Yes, when mounted on a redundant IOTA, a pair of 8C-PAIM01 modules operates in a secondary-tracking mode, providing seamless failover if the primary module detects an internal fault or loss of signal integrity.
