Product Description
HIMA F8650X Safety CPU Module (HIMax Series)
Lockstep Dual-Core CPU for SIL 3 Safety Instrumented Systems, Enabling High-Availability Safety Logic Processing
1. Product Overview

The HIMA F8650X is a central safety CPU module of the HIMax series, designed for HIMA Safety Instrumented Systems (SIS) to execute safety-related control logic, data processing, and fault diagnosis. It adopts a dual-processor lockstep architecture (two 32-bit Intel 386EX microprocessors running at 25 MHz) to ensure task-level redundant synchronization, meeting IEC 61508 SIL 3 and EN ISO 13849-1 PL e (Cat. 4) safety requirements. The module integrates comprehensive diagnostic functions, a 4-digit matrix display for real-time status monitoring, and safety-related watchdog output, making it suitable for critical process industries such as oil & gas, chemical, and power generation, providing reliable safety control for emergency shutdown, interlock protection, and other safety functions.
