Honeywell 900A01-0001 HC900 8-Channel Universal Analog Input Module

Product Overview

The Honeywell 900A01-0001 is a high-density, high-precision universal analog input module specifically engineered for the HC900 Control System. This module provides eight fully independent channels, each capable of interfacing with a diverse array of field sensors including thermocouples, RTDs (Resistance Temperature Detectors), and standard 4–20 mA or voltage transmitters.

By eliminating the need for external signal conditioning, the 900A01-0001 streamlines system architecture. It features integrated 16-bit A/D conversion, internal linearization, and automatic cold-junction compensation (CJC) for temperature sensors. Each channel is galvanically isolated, protecting the HC900 controller logic from field-side transients and electrical noise, making it a reliable choice for critical thermal processing and pharmaceutical manufacturing environments.
