Honeywell 900C72R-0100-44 HC900 Analog Input Module

Product Description

Overview

The Honeywell 900C72R-0100-44 is a high-density analog input module designed for the ControlEdge HC900 process and safety controller family. It provides a robust interface between field sensors and the HC900 controller, converting voltage and current signals into precise digital data for process monitoring and control. This module is part of Honeywell’s redundant “R” series, making it ideal for systems that require high availability and fault tolerance.

Key Features

High-Density Signal Processing

• Supports up to 16 analog input channels in a single module slot.

• Accepts multiple signal types including 4–20 mA, 0–20 mA, 1–5 V, 0–5 V, and 0–10 V DC.

Precision and Performance

• 16-bit Analog-to-Digital Converter ensures high-resolution measurements.

• Typical accuracy of ±0.1% of full scale.

• Fast update rates suitable for real-time process control loops.

Safety and Redundancy

• Fully compatible with HC900 redundant rack configurations.

• Hot-swappable design allows replacement without shutting down the system.

• On-board diagnostics detect open circuits, over-range conditions, and internal failures.

Isolation and Protection

• Galvanic isolation between field-side circuitry and controller backplane.

• Ruggedized construction supports harsh industrial conditions; optional conformal coating protects against moisture and corrosion.

Technical Specifications

Applications

• Process Control: Ideal for pressure, flow, and level measurements in chemical, pharmaceutical, and food processing plants.

• Thermal Systems: Precise feedback for furnace, boiler, and thermal process control.

• Redundant Safety Systems: Suitable for SIL-2 emergency shutdown or critical monitoring when paired with redundant HC900 CPUs.
