HIMA B9361 (5VDC Supplementary Power Supply Kit)

B9361 is a 5VDC supplementary power supply kit for the German HIMA H51q/H41q system, used for providing additional 5V power redundancy and expansion for the central rack (B5232/B5233) and I/O expansion rack (B9302), to address the power consumption over-limit issue of I/O modules in large systems and ensure the long-term stable operation of the SIS system. Basic Information

Standard Configuration

1 × B9361 Power Module: 5VDC/10A Output

1 × Installation Bracket: 19-inch Rack Mounting Part

1 × Power Cable: Connects system 24V bus to backplane

1 × Redundancy Connector: Synchronous signal for multi-module parallel connection

Key Functions and Features

Power Redundancy Expansion: The original 3 F7126 power supplies can support a maximum total current of 18A; after adding B9361, it can be expanded to 28A+, meeting the high power consumption module requirements of 16 slots B9302 full configuration.

Full Isolation Safety Design: Electrical isolation of input/output, suppressing ground loop interference, meeting SIL3 safety isolation requirements.

Online Maintenance Support: Modules support hot swapping, allowing online replacement without affecting system operation; faults trigger automatic alarms, facilitating rapid location.

Wide Temperature Industrial Grade Reliability: Stable operation within -20°C ~ +60°C, resistant to vibration, electromagnetic interference, suitable for harsh environments such as petrochemical and power industries.

Seamless Integration with H51q System: Directly compatible with B5232/B5233 central rack and B9302 expansion rack backplane, plug-and-play, no additional configuration required. Typical application scenarios

Large SIS/ESD System: Central Rack (B5233-2) + Multiple B9302 Expansion Racks, when all I/O modules are fully equipped, the power consumption exceeds 18A. Add B9361 for expansion.

High Power Consumption I/O Configuration: A large number of analog modules (such as F3237, F3337) or high-density digital modules. The power consumption of a single rack approaches the limit. Adding redundant power supplies for redundancy.

Redundant Power Architecture Enhancement: For devices with extremely high safety requirements (such as SIL3 certified projects), an additional 5V redundant power supply is added to completely eliminate the risk of single-point power failure.

Instructions for Using with B9302

B9302 is a 4U I/O expansion rack (16 slots), powered by the central rack; when fully equipped with high-power modules, it is prone to triggering power overload protection.

B9361 is directly installed in the 1U slot above or below the B9302 rack, outputs 5VDC to the backplane of the expansion rack, shares the power load of the central rack, and ensures the stable operation of the system.
