The Omron C200HW-BI101-V1 PLC Backplane Unit provides 10 slots for C200H and C200HS Programmable Logic Controller systems requiring expanded rack capacity. It distributes 5 VDC bus power across connected modules while providing the internal paths needed for coordinated data transfer between installed CPU, I/O, and compatible special-function units. Its 10-slot architecture supports larger controller configurations where multiple modules need to be organized within one expansion rack. This allows machine-control systems to increase module capacity while retaining the established PLC architecture. The C200HW-BI101-V1 supports higher-capacity rack expansion and belongs to the 10-slot PLC backplane range within Omron factory automation.
