HIQuad X System Manual: Comprehensive and in-depth analysis of HIMA SIL 3 safety automation system

1. System Overview and Core Advantages

HIQuad X is the next-generation safety related programmable electronic system (PES) launched by HIMA, designed to meet the dual requirements of high availability and functional safety in the industrial sector.

Core Features

Safety level: The system design complies with IEC 61508 SIL 3 and EN ISO 13849-1 PL e standards.

Programming tools: Use validated SILworX programming tools for configuration, monitoring, and programming.

Architecture: Supports the principles of "de excitation trip" and "excitation trip", suitable for fire alarm systems (compliant with DIN EN 54-2 and NFPA 72) and explosion-proof areas (Zone 2).

Compatibility: Supports existing HIQuad I/O modules to ensure a smooth transition for system upgrades.

2. System architecture: H51X and H41X series

The HIQuad X adopts a modular design and is mainly divided into two series: H51X (high-performance, highly expandable) and H41X (compact, independently expandable).

2.1 H51X Series (Extended System)

Suitable for scenarios with large-scale I/O requirements.

Structure: 1 basic rack+up to 16 expansion racks.

I/O capacity: up to 256 I/O modules, totaling up to 4096 I/O points.

Expansion rack: Each expansion rack supports up to 16 I/O modules.

Communication module: The basic rack supports up to 10 communication modules.

2.2 H41X series (compact system)

Suitable for applications with limited space or moderate I/O points.
