CC-PAIM01 51405045-175 | Honeywell Low-Level Analog Input Multiplexer IOP Module

Overview

The Honeywell CC-PAIM01 51405045-175 is a Series C Low-Level Analog Input Multiplexer (LLMUX) IOP module. It is uniquely engineered to interface the Experion Series C platform with existing solid-state PMIO LLMUX Field Termination Assemblies (FTAs), supporting up to 64 channels of high-density, fully-isolated temperature and millivolt measurements.

Installation Notes

• Install the compatible PMIO FTAs inside dedicated FTA channels (Note: these mounting spaces are similar to but distinct from standard Series C channels).
• Connect the CC-PAIM01 module interface to the field termination block via the required cable adapter option up to a maximum distance of 1000 feet.
• Configure the line frequency integration parameters to exactly 50 Hz or 60 Hz to ensure the 120 dB common-mode rejection performance.
• Verify that the total loop resistance for active 3-wire/4-wire RTD sensor paths remains strictly under the 15 Ω threshold.
