HITACHI BSU09H-B – 9-Slot Base Rack Module | H Series PLC Platform
Engineering Background
The HITACHI BSU09H-B is a 9-slot base rack module (backplane) designed for the HITACHI H Series programmable logic controller platform. As the structural and electrical backbone of the control system, it provides the physical mounting slots and internal bus interconnections required to integrate CPU, power supply, I/O, and communication modules into a unified, high-reliability automation architecture. This module is widely deployed in process control, machine automation, and infrastructure management applications across Asia-Pacific and global industrial markets.
Product Positioning
The BSU09H-B is the standard 9-slot rack option within the H Series ecosystem, offering a balance between system density and expansion flexibility. It is the preferred choice for mid-scale control panels where 5 to 8 functional modules are required alongside the CPU and power supply. Konmask.com supplies this module as a genuine OEM component, sourced through verified industrial distribution channels, with full traceability documentation available upon request.

Proven Application Environments
- Process Manufacturing: Chemical, pharmaceutical, and food & beverage plants requiring deterministic scan-cycle control with multi-module I/O expansion.
- Machine Automation: CNC machining centers, packaging lines, and assembly systems where compact rack density reduces panel footprint.
- Infrastructure & Utilities: Water treatment, HVAC control, and power distribution systems demanding long-lifecycle hardware with proven field reliability.
- OEM Panel Builders: System integrators standardizing on HITACHI H Series for multi-project deployments benefit from the BSU09H-B’s consistent slot geometry and bus compatibility.
Engineering Advantages
- 9-Slot Capacity: Accommodates up to 7 functional I/O or communication modules alongside CPU and power supply — optimal for mid-complexity control architectures.
- Robust Bus Integrity: Gold-plated backplane connectors ensure low-resistance, vibration-tolerant module seating across the full operating temperature range.
- Modular Scalability: Supports expansion via remote I/O racks when system I/O count exceeds single-rack capacity, preserving the base architecture investment.
- Long Product Lifecycle: HITACHI H Series components maintain multi-decade availability through authorized distribution, reducing obsolescence risk for long-running installations.
- Simplified Maintenance: Individual module hot-swap capability (where supported by CPU firmware) minimizes downtime during field servicing.
System Architecture & Signal Flow
In a standard H Series control system, the BSU09H-B serves as the central interconnect layer. The power supply module (installed in the designated power slot) distributes regulated DC bus voltage across all occupied slots via the backplane. The CPU module communicates with I/O and specialty modules through the internal parallel bus, executing the user program scan cycle and managing data exchange. Communication modules installed in the remaining slots interface with field networks (e.g., PROFIBUS, Ethernet/IP, CC-Link) or operator interfaces, with all inter-module data routed through the BSU09H-B backplane without external wiring.
This architecture eliminates inter-module cabling complexity, reduces EMI exposure, and provides deterministic bus timing — critical for high-speed discrete and analog control loops.

Technical FAQ
Q: Is the BSU09H-B compatible with all HITACHI H Series CPU modules?
A: The BSU09H-B is designed for the HITACHI H Series platform. Compatibility with specific CPU models (e.g., H-300, H-700, H-2000) should be verified against the HITACHI H Series hardware manual. Contact us for compatibility confirmation before ordering.
Q: Can I mix I/O module brands in the BSU09H-B slots?
A: No. The H Series backplane bus is proprietary to HITACHI H Series modules. Only HITACHI H Series-compatible modules should be installed in BSU09H-B slots.
Q: What is the maximum I/O count supported with the BSU09H-B?
A: With 7 available I/O slots and HITACHI’s high-density I/O modules, a single BSU09H-B rack can support several hundred I/O points. Exact capacity depends on the specific I/O module models selected.
Q: Is this a new or refurbished unit?
A: Konmask.com supplies both new and certified pre-owned units depending on availability. Product condition is clearly stated at the time of quotation. All units pass pre-shipment inspection regardless of condition grade.
Q: Do you provide a warranty?
A: Yes. Konmask.com provides a 90-day functional warranty on all supplied components. Extended warranty options are available for volume orders.
