The HIMA F8650X is a high-reliability central processing module designed for safety-critical industrial automation systems, specifically optimized for the HIMA H51q-MS, -HS, and -HRS platforms. It combines advanced processing capabilities with stringent safety certifications to ensure seamless operation in hazardous environments. Below is a detailed technical overview:
The F8650X serves as the core controller for industrial safety systems, enabling real-time monitoring, control logic execution, and communication with peripheral devices. It features a dual-core Intel 386EX microprocessor (25 MHz clock speed) with clock-synchronized redundancy, ensuring fault tolerance and continuous operation even in the event of a single-core failure . This architecture supports task-level redundancy synchronization with a switching time of <50 ms, meeting the highest safety integrity requirements .
Power Supply:
- Rated voltage: 24 V DC (typical power consumption: 15 W) .
- Optional redundancy: Supports dual power inputs for fail-safe operation.
Communication Interfaces:
- Base Interfaces: 2x electrically isolated RS-485 ports for Modbus RTU/ASCII communication .
- Ethernet Connectivity: Requires the F8627X communication module for Ethernet/IP, Profinet, Modbus TCP, and SafeEthernet protocols .
- Expansion: Backplane bus integration for connecting I/O modules, additional communication modules, or redundant controllers .
Memory:
- Flash-EPROM: 1 MB for the operating system and user programs.
- SRAM: 1 MB for data storage .
Safety Certification:
- SIL 3 (IEC 61508) and PL e (ISO 13849) compliance, ensuring suitability for life-critical applications .
- TÜV-certified fault detection and diagnostic capabilities .
Environmental Specifications:
- Operating Temperature: -20°C to +60°C .
- Storage Temperature: -40°C to +85°C.

- Enclosure Protection: IP20 (optional higher ratings available) .
Physical Dimensions:
- Size: 8 SU (Standard Units) in width, compatible with DIN rail mounting .
- Weight: Approximately 0.5 kg .
Dual-Core Redundancy:
- Two Intel 386EX processors operate in lockstep, continuously verifying each other’s outputs. A single-core failure triggers an automatic switch to the redundant core within 50 ms, ensuring zero downtime .
Advanced Communication:
- Supports Modbus RTU/ASCII natively and extends to Ethernet-based protocols (e.g., Ethernet/IP, Profinet) via the F8627X module .
- Protocol Translation: Bridges legacy fieldbus systems (e.g., Profibus) with modern Ethernet networks, enabling seamless integration with third-party devices .
Safety-Critical Design:
- Safe Watchdog: Monitors system health and triggers a fail-safe state if anomalies are detected .
- Hot-Swap Capability: Allows module replacement without shutting down the system, minimizing maintenance downtime .
Diagnostic Functions:
- Real-Time Monitoring: Built-in CRC-16 checks and hardware self-tests identify faults in communication, power, and memory .
- Four-Digit Matrix Display: Provides status codes and error messages for quick troubleshooting .
Flexible Programming:
- Supports IEC 61131-3 languages (Ladder Logic, Structured Text, Function Block Diagram) via HIMA’s HiCAD engineering tool .
- Edge Intelligence: Optional integration with OPC UA for cloud-based analytics and predictive maintenance .
Process Industry:
- Chemical/Oil & Gas: Emergency shutdown systems (ESD), burner management systems (BMS), and critical process control .
- Pharmaceuticals: Compliance with FDA 21 CFR Part 11 through secure data logging and audit trails .
Power Generation:
- Nuclear reactor protection systems, steam turbine control, and grid stability management .
Transportation:
- Railway signaling systems, tunnel ventilation control, and airport baggage handling .
Heavy Machinery:
- Crane control, robotic manufacturing cells, and mining equipment safety interlocks .
- Modular I/O: Connects to HIMA’s extensive range of digital/analog input/output modules (e.g., F3112, F7131) via the backplane bus .
- Redundant Configurations: Supports dual-core redundancy, dual power supplies, and redundant communication paths (e.g., via F8627X) for maximum availability .
- Warranty: 12 months from date of delivery .
- Standards: Compliant with IEC 61508, ISO 13849, and EN 61000-6-2/3 for EMC immunity .
