Overview

The Honeywell 900C75-0460 is part of the ControlEdge HC900 process and safety system, engineered for applications requiring high reliability and continuous operation. This redundant controller CPU enables seamless failover between primary and backup processors, ensuring that control logic execution continues without interruption during hardware faults or maintenance.

Built around a 32-bit RISC PowerPC e300 processor, the module delivers fast and deterministic performance for complex control strategies. It supports up to 15,000 function blocks, making it suitable for large-scale automation systems. Moreover, the 900C75-0460 is SIL 2 certified, making it ideal for safety instrumented systems in industries such as chemicals, oil & gas, and power generation.

In addition, the module features 128 MB ECC-protected DDR2 RAM with battery backup, ensuring data integrity and retention during power loss. Its compact design and modular architecture allow easy integration into HC900 racks, supporting up to 2304 analog input points.

Technical Data

Typical Applications

• Safety Instrumented Systems (SIS): Ensures continuous control and fault tolerance in hazardous processes.

• Batch and Continuous Process Control: Manages complex logic and large I/O networks in chemical and pharmaceutical plants.

• Power Generation: Supports turbine and boiler control with high availability.

• Oil & Gas: Provides reliable control in upstream and downstream operations.

• Water Treatment: Maintains uninterrupted control of pumps, valves, and sensors.

For instance, in a refinery, the 900C75-0460 can switch seamlessly to a backup CPU during a fault, maintaining control of critical processes without downtime.
