The HIMA F8650A is a processor module designed for safety-instrumented systems (SIS). Here is the detailed information:
- Manufacturer: HIMA.
- Type: Processor module.
- Country of Origin: Germany.
- Weight: 0.9 kg.
- Dimensions: 144 x 160 x 40 mm.
- High Safety Level: Certified to SIL 3 according to IEC 61508, ensuring high safety and reliability in safety-critical applications.
- Dual-processor Design: It is a dual-processor module with two Intel 386 EX microprocessors running at 25 MHz, providing strong processing power and ensuring the stability and reliability of the system.
- Self-diagnosis Function: HIMA's self-diagnosis technology can diagnose all the hardware and software operations of the system within one scan period, with a diagnostic rate of 99.99%. The fault information of the CPU and I/O cards can be displayed as 4-character characters in the information window of the CU and on the workstation of the system.
- Redundancy Design: Based on HIMA's proven triple modular redundancy (TMR) architecture, which provides three independent execution paths for each task, ensuring that the system remains operational even if one or two of the paths fail.
- Microprocessor: 2x Intel 386 EX, 25 MHz.
- Memory: 1 MB flash-eprom per microprocessor, 1 MB sram per microprocessor.
- Interfaces: 2x RS-485 serial interfaces, 4-digit matrix display.
- Watchdog: Safety-related watchdog with output 24 V, loadable up to 500 ma, short-circuit proof.
- Power Supply: 5 V / 2 A.
- Operating Temperature: 0 to 50 °C.
The F8650A is widely used in emergency shutdown systems (ESD), fire and gas detection systems, burner and boiler control systems, turbomachinery control systems, pipeline control systems, high-integrity pressure protection systems (HIPPS), and other fields.
