Introduction
The Honeywell 8C‑PAZMA1 serves as a dedicated low‑level analog input module within Honeywell’s Series‑8 I/O ecosystem, designed to interface directly with temperature sensors such as RTDs (Resistance Temperature Detectors) and thermocouples (TC). Its role is to convert low‑level analog signals — typically millivolt thermocouple outputs or low-resistance RTD signals — into accurate digital measurements, delivering them reliably to the control system for monitoring, logging, or control action. This module is optimized for high channel density, signal integrity, and stable performance under the demanding conditions common in industrial process plants.
