Core carrier of security system: providing physical installation and backplane bus connection for H51q HRS security CPU system, ensuring high-speed data exchange between modules, supporting security logic operation and fault diagnosis.

Redundant power supply and monitoring: Integrate three F7126 power modules (5V output parallel) with F7131 power supply monitoring to achieve power supply redundancy and fault alarm, and improve system power supply reliability.

Bus terminal enhancement: Configure 4 F7546 bus terminal modules to optimize bus signal integrity, adapt to long-distance bus communication, and reduce signal interference risks.

Modular expansion maintenance: The slot based design supports flexible configuration and hot plugging of CPUs, co processors, and I/O modules (some modules), eliminating the need for overall shutdown during maintenance and reducing maintenance time.

HIMA H51Q-HRS B5233-2 Redundant Central Module

High compatibility integration: compatible with HIMA H51q series I/O subracks (such as B9302) and other safety components, making it easy to build distributed safety control systems and adapt to the safety control needs of large factories in multiple areas.
