HIMA F8650 Central Processing Unit
HIMA F8650
1. Overview
Product Positioning: HIMA F8650 is a safety-related CPU module designed by HIMA, belonging to its PES (Process Automation Safety) series. It serves as the Central Processing Unit (CPU) for Safety Instrumented Systems (SIS).
Core Function: Acting as the “brain” of the safety control system, it executes safety-related control logic, monitors safety-related input signals (such as sensors, buttons), and outputs safety-related control signals (such as valve closing, power cutoff).
Design Standards: Complies with IEC 61508/61511 standards, supporting high-integrity safety applications.

3. Key Features
Dual Channel Redundancy: The F8650 adopts a dual-processor redundant structure. Even if one processor fails, the other can still operate normally, ensuring high availability and safety of the system.
Clock Synchronization: The clocks of the two processors are synchronized, ensuring data consistency between the two channels and reducing the possibility of misjudgment.
Fault Diagnostics: Equipped with powerful self-diagnostic functions, it can real-time monitor the system’s health status, detect hardware faults or software abnormalities, and issue alarms via the display.
Versatility: Supports multiple safety-related communication protocols (e.g., Profibus, Modbus) and is compatible with various I/O modules, flexibly adapting to different industrial sites.

4. Structure and Composition
Core Hardware
- Dual CPU Motherboard: Integrates two independent CPU motherboards that are mirror images of each other.
- Memory Modules: Flash-EPROM and SRAM for storing programs and real-time data.
Peripheral Components
- Communication Card: Responsible for data exchange with upper computers or other controllers.
- Display Panel: User interface for showing real-time status.
- Power Supply Module: Provides stable 24V DC power input with redundant design.

6. Installation & Maintenance
Installation Method
- DIN Rail Mounting: The F8650 adopts a standard DIN rail design, facilitating installation and replacement in cabinets.
- Backplane Connection: Connects to I/O modules or power supply modules via a backplane.
Maintenance Requirements
- Regular Inspection: Use the display and remote diagnostic tools to regularly check the system’s health status, focusing on fault indicators and error codes.
- Redundancy Testing: Regular redundancy function tests are required to ensure both channels can work normally.
- Firmware Update: Perform firmware or software upgrades under official guidance to fix known defects or enhance functions.
