Triconex and Pepperl+Fuchs security solutions

Core module: HiC2441 is known as the "universal" module, which can be configured as AI, AO, DI or DO, greatly simplifying engineering design and spare parts inventory.

Segmented functional modules: In addition, the system also supports mixing specific specialized modules (such as HIC2025 for AI, HIC2031 for AO, HIC2821 for DI, etc.) onto the universal terminal board. This flexibility allows engineers to define and adjust I/O types in the shortest possible time based on actual on-site needs, making it a powerful tool for responding to project changes.

Safety Integrity Level (SIL) and Global Certification

In the field of functional safety, the IEC 61508 standard defines four safety integrity levels (SIL). Pepperl+Fuchs' H-System provides a solution for Tricon CX that covers a wide range of SIL 2 and SIL 3 application requirements.

SIL 2 applications: Most analog inputs, digital inputs, and non critical circuits typically use SIL 2 certified modules, which already meet the safety requirements of the vast majority of process industries.

SIL 3 application: For critical interlock circuits in emergency shutdown (ESD), such as final component control, critical safety interlock inputs, etc., H-System provides SIL 3 modules certified by authoritative organizations such as T Ü V (such as HIC2025ES, HIC2031ES, HIC2883, etc.). These modules meet the highest standards in terms of hardware fault margin and diagnostic coverage, ensuring that the system can still operate safely in the event of a single fault.

H-System is one of the most thoroughly tested and documented intrinsic safety solutions on the market. This not only means that the product itself meets the standards, but also that Pepperl+Fuchs can provide detailed safety manuals, SIL calculation certificates, and Failure Mode Data (FMEDA), greatly reducing the workload of end users in the SIL Verification stage. In addition, the system has obtained major global explosion-proof certifications including ATEX, IECEx, FM, etc., truly achieving "one solution, globally applicable".

Configuration tools and ecosystem support

To assist engineers in quickly selecting and generating accurate technical documentation, Pepperl+Fuchs provides a powerful online configurator. By accessing the portal website, users can automatically match the optimal H-System module and terminal board combination based on the specific I/O card model and signal type of Tricon CX. This tool not only improves selection efficiency, but also generates relevant order numbers and technical parameters, reducing human errors.

In addition to intrinsically safe isolation barriers for Tricon CX, Pepperl+Fuchs, as Schneider Electric's main supplier, also offers a range of seamless product combinations, including:

Bus system: FOUNDATION Fieldbus, PROFIBUS PA solution.

HART multiplexer: enables efficient integration of multiple HART smart instruments.

Signal conditioner: used for signal isolation and conversion in non intrinsic safety environments.

Special HMI solution: an operating interface that adapts to harsh environments.

Mobile devices and blowing systems: further improving the overall solution for hazardous areas.
