Overview

The F8652E is the central processing unit of HIMA’s HIQuad safety controller series, engineered for applications requiring high availability and functional safety. It features a redundant architecture with dual Intel 386EX processors running in clock synchronization, ensuring continuous operation even in the event of hardware failure.

Moreover, the module supports high-speed sampling at 25 microseconds, enabling rapid response to input changes and precise control in real time. In addition, it includes comprehensive diagnostic capabilities such as LED indicators and a four-digit alphanumeric display for on-site fault identification and system status monitoring.

Therefore, the F8652E is widely used in industries such as oil and gas, chemical processing, and power generation, where safety integrity and system uptime are paramount.

Technical Data

In addition, the module supports hot-swapping and is compatible with HIMA’s engineering tools for configuration and maintenance.

Typical Applications

• Emergency Shutdown Systems (ESD): Ensures safe shutdown of critical processes in hazardous environments.

• Burner Management Systems (BMS): Controls and monitors combustion systems in power plants and refineries.

• Turbine Control: Provides high-speed logic execution for turbine protection and operation.

• Process Safety Systems: Used in chemical and petrochemical plants for interlocks and safety loops.

For instance, in a refinery, the F8652E can detect abnormal pressure conditions and trigger emergency shutdowns within milliseconds, preventing accidents and equipment damage.

Moreover, its SIL 3 certification and redundant design make it suitable for applications where failure is not an option.
