The HIMA HIMatrix F35 is a high-performance, compact programmable safety controller designed for use in safety-critical applications requiring high-speed processing and a small footprint. As part of the HIMatrix family, the F35 is certified for use in functional safety applications up to SIL 3 (IEC 61508) and PL e (EN ISO 13849-1). It is particularly well-suited for distributed safety systems, burner management systems (BMS), and high-speed turbomachinery control.

Application Fields
The F35 is deployed in environments where speed and safety are paramount:
- Oil & Gas: Emergency Shutdown (ESD) systems and Fire & Gas (F&G) monitoring for offshore platforms.
- Burner Management (BMS): Controlling and monitoring industrial burners and boilers in accordance with EN 298.
- Railways: SIL 4-rated signaling and interlocking logic for rail infrastructure.
- Logistics & Intralogistics: High-speed safety control for automated storage and retrieval systems (AS/RS).
- Turbomachinery: Overspeed protection and surge control for large compressors and turbines.
Product Instructions for Use
- Mounting and Grounding: Mount the F35 on a standard DIN rail. Ensure the rail is properly grounded to the cabinet’s functional earth to minimize electromagnetic interference.
- Wiring: Use shielded cables for analog inputs. Ensure that the 24V DC power supply is stable and meets the safety-rated voltage tolerances.
- Programming: The F35 is programmed using the SILworX engineering tool. Logic must be validated and verified according to the safety lifecycle requirements of IEC 61508.
- Network Setup: If using safeethernet for distributed I/O, ensure the network topology is redundant and that the IP addresses are correctly assigned via the SILworX project configuration.
Q&A: Frequently Asked Questions
Q: What is the difference between the F35 01 and F35 03 variants? A: Different variants typically offer variations in I/O count or specialized communication protocols (e.g., one may support PROFINET while another is optimized for Modbus). Always match the specific part number to your project requirements.
Q: Can the F35 be used as remote I/O? A: Yes, while the F35 is a full controller, it can be configured to operate as a remote I/O node in a larger HIMA system controlled by a HIMax or another HIMatrix unit.
Q: Does it require a battery for program storage? A: No, the safety program and configuration data are stored in non-volatile Flash memory. A battery is only required if the real-time clock (RTC) needs to be maintained during power-off periods.
