HIMA F8621A 984862160

The HIMA F8621A (Order No. 984862160) is a processor/co-processor module used in HIMA’s H41q/H51q safety-related control systems. Available references identify it as a coprocessor module for the H41Q/H51Q, rather than a conventional analog input module.

Technical Description

  • Brand: HIMA
  • Model: F8621A
  • Order Number: 984862160
  • System: HIMA H41q / H51q
  • Module type: Processor / Co-processor module
  • Processor: HD64180, approximately 10 MHz
  • Memory: Static RAM and EPROM
  • Communication: 2 × isolated RS-485 interfaces
  • Transmission rate: Up to 57.6 kbit/s
  • Communication modes: Half-duplex serial communication
  • Battery-backed memory: Yes
  • Diagnostics: System and hardware monitoring functions
  • Status indication: Diagnostic display and LEDs

The F8621A contains its own microprocessor and communication processing resources. Its two galvanically isolated RS-485 interfaces support configurable transmission rates from 300 to 57,600 bps, making it suitable for communication within the HIMA safety-control architecture.

Applications

The module is primarily associated with HIMA H41q/H51q safety PLC/SIS systems, where it provides processing and communication functions within the redundant safety-control architecture. These systems are designed for applications requiring high availability and fault tolerance.

Typical applications include:

  • Safety Instrumented Systems (SIS)
  • Emergency Shutdown (ESD) systems
  • Process safety control
  • Oil & gas and petrochemical plants
  • Power generation
  • Chemical and process industries
  • Legacy HIMA H41q/H51q installations

Important Note

Some online listings incorrectly describe the F8621A as an analog input module or a generic communication module. The more specific historical product information identifies 984862160 / F8621A as a H41Q/H51Q coprocessor/processor module. Radwell also lists it as discontinued by the manufacturer, so it is generally encountered as a legacy/maintenance spare.

Conclusion: HIMA F8621A 984862160 is a legacy H41q/H51q processor/co-processor module with isolated RS-485 communication capability, intended for reliable processing and communication in HIMA safety control systems.
