Honeywell 8C-PAIMA1 51454473-175 Low Level Analog Input RTD Module

The Honeywell 8C-PAIMA1 51454473-175 is a high-performance low-level analog input module engineered for accurate and reliable temperature sensing using Resistance Temperature Detectors (RTDs). As part of the Experion Process Knowledge System (PKS) and integrated into the C300 control system, this module is specially designed to meet the demands of precise temperature measurement in industrial environments.

Capable of interfacing with a range of RTD types including Pt100, Ni100, and others, the 8C-PAIMA1 offers multi-channel support with high accuracy and built-in diagnostics. Its differential signal processing and advanced noise rejection capabilities make it suitable for harsh and electromagnetically noisy environments.

The module operates within a redundant, modular architecture that supports fast channel scanning, HART device pass-through (if applicable), and complete integration into Honeywell’s Experion PKS. It is ideal for critical control applications in process industries such as petrochemical, energy, pharmaceutical, and food processing.
