Product Overview

The 900C75-0360-00 is a CPU module for the Honeywell ControlEdge HC900 process controller family, serving as the central processing unit in HC900 control systems.

This module provides computational power and real-time logic execution needed for industrial automation applications from small skids to large distributed networks.

Key Features & Specifications

• Processor: 32-bit RISC CPU (PowerPC-based) optimized for real-time logic and deterministic control.
• Power supply: 24 VDC input (standard for HC900), enabling compatibility with industrial distribution.
• Power consumption: Typically 40–80 W minimizing cooling requirements in cabinets.
• Memory: Built-in RAM/flash storing control logic, configurations, and process data.
• Communication: Ethernet, RS-485, USB, and ControlNet support for HMI, SCADA, and controller connectivity.
• I/O support: Modular architecture for seamless analog/digital I/O expansion.
• Programming: IEC 61131-3 and proprietary HC900 schemes for flexible control implementation.

Typical Applications / Use Cases

HC900 CPU modules serve diverse industrial sectors for process, thermal, and machine control.

• Thermal systems including boilers, furnaces, kilns, and dryers requiring precise temperature control.
• Process industries (chemical, petrochemical, water treatment, food) requiring pH, pressure, flow, level control.
• Unit operations such as reactors, fermenters, and sterilizers with complex feedback logic.
• Auxiliary systems including HVAC, utilities, and distributed I/O coordination.

Advantages / Why It Matters

• Modular and scalable: Start with single CPU and scale to hundreds of I/O points.
• Flexible communications: Multiple interfaces integrate diverse HMI/SCADA and legacy systems.
• Robust control: Rich function blocks for complex tasks without custom programming.
• Industrial reliability: Watchdog timers and isolation ensure mission-critical operation.
