Process Safety I/O Solution – HIMA F3 DIO 16/801 | HIMax / HIMatrix Series
Where This Product Is Used
The HIMA F3 DIO 16/801 is a certified Safety Integrity Level 3 (SIL 3) remote digital I/O module engineered for deployment in the most demanding functional safety applications across heavy industry. Engineers specify this module in environments where a single I/O failure could trigger catastrophic consequences:
- Oil & Gas – Upstream & Midstream: Emergency Shutdown Systems (ESD), wellhead control panels, pipeline isolation valve control, and compressor protection logic.
- Petrochemical & Refining: Burner Management Systems (BMS), high-integrity pressure protection systems (HIPPS), and reactor interlock loops.
- Chemical Processing: Toxic gas detection interlock circuits, exothermic reaction shutdown logic, and pressure relief valve monitoring.
- Power Generation: Turbine trip systems, boiler safety interlocks, and generator protection panels.
- Offshore Platforms: Fire & Gas (F&G) detection systems, deluge valve control, and platform ESD architectures.
- LNG Terminals: Cryogenic valve control, loading arm interlock systems, and vapor detection shutdown loops.
In all of these environments, the F3 DIO 16/801 operates as a remote I/O node within HIMA’s HIMax or HIMatrix safety controller architectures, extending the safety logic solver’s reach to field devices while maintaining full SIL 3 integrity across the I/O boundary.

Application-Specific FAQ
- Q: Can the F3 DIO 16/801 be used in a SIL 3 ESD application without additional redundancy?
- A: Yes. The F3 DIO 16/801 is certified to SIL 3 in 1oo1D architecture, meaning a single module can achieve SIL 3 in low-demand mode applications, subject to proof test interval and PFDavg verification in your SIL calculation tool (e.g., exSILentia, SISTEMA).
- Q: Is this module compatible with HIMatrix as well as HIMax controllers?
- A: The F3 series designation covers modules used across HIMA’s HIMax and HIMatrix platforms. Please confirm backplane compatibility with your specific controller model before ordering. Our technical team can assist with compatibility verification.
- Q: What is the typical proof test interval for this module?
- A: HIMA’s safety manual specifies proof test intervals typically ranging from 1 to 10 years depending on the target SIL and architecture. Refer to the HIMA F3 DIO 16/801 Safety Manual (available on request) for PFDavg tables.
- Q: Do you supply the HIMA SILworX software license alongside the hardware?
- A: We supply hardware components. SILworX software licenses are managed directly through HIMA’s official channels. We can facilitate introductions to HIMA’s regional support team if required.
- Q: Can this module be used in ATEX Zone 1 hazardous areas?
- A: The F3 DIO 16/801 itself is rated for installation in safe areas or Zone 2 (with appropriate enclosure). For Zone 1 applications, field-mounted Zener barriers or galvanic isolators must be used between the module and field devices. Contact us for barrier selection guidance.
