HIMA H51q-HRS B5233-2 997205233 Safety Instrumented System

HIMA H51q-HRS B5233-2 Overview

The HIMA H51q-HRS B5233-2 is a critical component of the Safety Instrumented System (SIS) developed by Germany’s HIMA (known as “HIMA Black Horse”) for safety-critical industrial processes.

Product Positioning

• High-reliability hot-standby redundant controller module, designed for applications requiring Safety Integrity Level SIL 3 (IEC 61508).
• Fully compatible with the HIMA H51q series platform and can be used together with H51q-MS, H51q-HS, and other safety controllers.

Technical Features

• Dual CPU Redundancy: Two identical controllers operate in synchronization. If the primary controller fails, the backup takes over automatically, ensuring seamless system operation.
• Redundant Power Supply: Dual 24 V DC power inputs enhance resistance to power failures.
• Communication Interfaces: Supports Profibus, DP, Ethernet, and other industrial fieldbuses for easy integration with upper-level systems such as DCS and PLC.
• Environmental Adaptability: Operating temperature range –20 °C to +60 °C, suitable for harsh industrial environments.
• Modular Design: 5U 19″ rack-mount structure (B5233-2), enabling flexible cabinet installation and system expansion.

Main Application Fields

• Power plant DCS monitoring systems
• Intelligent flat glass tempering furnace systems
• PLC-based programmable conveyor control systems
• Coke oven control systems
• Intelligent fire-fighting water supply systems
• Constant-flow chemical dosing systems
• Substation automation in paper and textile production lines

Certification and Quality

• Certified by TÜV to SIL 3, meeting international SIS standards.
• Manufactured with original German components, featuring anti-counterfeit packaging and quality assurance, with support for rapid field delivery.

Selection Guidance

• For process control systems requiring high availability (hot-standby) and strict safety integrity, the H51q-HRS B5233-2 is the standard choice.
• When used together with existing H51q-MS/HS controllers, I/O expansion and redundancy can be achieved within the same cabinet.

Conclusion

The HIMA H51q-HRS B5233-2 is a hot-standby redundant controller module designed to meet SIL 3 safety requirements. Featuring dual CPUs, dual power supplies, industrial bus compatibility, and a wide operating temperature range, it is widely applied in power generation, chemical processing, steel, and paper industries to build safety-critical systems.
