Technical Specifications

Main Features and Advantages

The HIMA F8628X stands out for its dual-channel architecture, which provides redundancy and fault tolerance. This design ensures that if one channel fails, the other continues to operate, maintaining safety functions without interruption. The module’s SIL 3 certification under IEC 61508 guarantees its suitability for applications requiring the highest level of functional safety, such as nuclear power plants, chemical processing facilities, and oil refineries.

A key advantage of the HIMA F8628X is its high-speed data processing capability, which enables real-time monitoring and control of safety-critical processes. The module’s 32-bit microcontroller and ample memory (512 KByte Flash-EPROM, 256 KByte SRAM) allow for complex safety logic execution, ensuring that safety functions are performed accurately and efficiently. Additionally, the module’s electrically isolated RS-485 interfaces prevent ground loops and electromagnetic interference, ensuring reliable communication with other system components.

The HIMA F8628X also features comprehensive self-diagnostic capabilities, which continuously monitor the module’s health and performance. These diagnostics include checks on processor status, memory integrity, and communication links, providing early detection of potential faults. The module’s front-panel LED indicators provide visual feedback on system status, simplifying troubleshooting and maintenance. For enhanced reliability, the HIMA F8628X supports hot-swappable replacement, allowing modules to be replaced without powering down the system, minimizing downtime.

Another notable feature is the module’s wide operating temperature range (-20°C to +60°C) and compact form factor, making it suitable for installation in space-constrained environments. The module’s low power consumption (5 V DC / 1000 mA) reduces energy costs and heat generation, contributing to overall system efficiency. The HIMA F8628X is also compatible with HIMA’s ELOP II or SILworX engineering tools, which streamline safety logic development and system debugging, reducing engineering time and costs.

Application Fields

In the oil and gas industry, the HIMA F8628X is widely used in emergency shutdown systems (ESD) and fire and gas detection systems. Its SIL 3 certification and dual-channel architecture make it ideal for preventing catastrophic failures in refineries, pipelines, and offshore platforms. The module’s ability to handle complex safety logic ensures rapid response to hazardous conditions, protecting personnel and equipment.

For chemical processing plants, the HIMA F8628X controls critical processes such as reactor temperature and pressure monitoring. Its high-resolution I/O capabilities and real-time data processing enable precise control of chemical reactions, improving product quality and reducing waste. The module’s diagnostic features simplify compliance with safety regulations, lowering audit risks.

The HIMA F8628X is also extensively used in power generation, where it manages turbine overspeed protection and boiler feedwater control. Its compatibility with legacy DCS platforms makes it a preferred choice for retrofitting aging infrastructure without disrupting production. Additionally, in nuclear power plants, the module ensures safe operation of reactor cooling systems, meeting stringent regulatory requirements.

Beyond traditional sectors, the HIMA F8628X excels in marine and offshore applications, such as FPSO vessels and drilling rigs, where salt corrosion and vibrations are persistent threats. By consolidating multiple safety functions into a single unit, the module reduces cabinet space requirements and simplifies wiring complexity, offering tangible benefits for capital-intensive projects.

In the pharmaceutical industry, the HIMA F8628X is used to monitor and control critical processes, such as sterile filtration and aseptic filling, ensuring compliance with Good Manufacturing Practices (GMP). Its high-precision analog inputs and outputs enable accurate control of process variables, ensuring product consistency and quality.

Installation and Maintenance

Pre-installation preparations: Before installing the HIMA F8628X, ensure that the installation environment meets the specified temperature (-20°C to +60°C) and humidity (5–95% RH non-condensing) requirements. Verify that the power supply complies with the 5 V DC nominal voltage (1000 mA) and that grounding follows IEC 60204-1 standards to prevent electrical noise interference.

During mounting, use the provided DIN rail clips or panel mount hardware to secure the module. Ensure all cable connections are tight and secure, using torque-controlled screwdrivers to avoid loose terminals. After physical installation, validate communication links using HIMA’s SILworX tool, which auto-detects module configurations and firmware versions.

Maintenance suggestions: Regularly inspect the module’s front-panel LEDs for diagnostic codes indicating processor faults or communication errors. Schedule biannual firmware updates to patch security vulnerabilities and improve functional safety. For modules operating in corrosive environments, clean terminals annually with isopropyl alcohol and apply dielectric grease to prevent oxidation.

Avoid using non-HIMA-certified replacement parts, as these may compromise SIL certification. In case of module replacement, utilize the hot-swap feature to minimize process downtime and recalibrate safety thresholds post-installation.
