Physical Layout and Connector Details

The Fuji FSB088H weighs 0.72 kilograms for stable mounting. Its 260 mm width accommodates eight standard Fuji modules. Two LED indicators show power status and communication link. A 50‑pin female connector accepts the expansion ribbon cable. Each slot includes a locking mechanism for secure module retention. The board uses a passive design without onboard energy storage.

Installation and System Integration

Mount this expansion baseboard horizontally inside your control panel. Use either DIN rail clips or M4 screws for fixation. Then connect the 50‑pin ribbon cable to the main CPU rack. Insert your I/O modules from left to right sequentially. The backplane automatically receives 5V power from the main rack. Consequently, you do not need a separate power supply for this board. For larger systems, connect multiple expansion baseboards in series.

Compatibility and Application Notes

This expansion baseboard works with Fuji CPU racks and power supplies. It supports all standard digital and analog I/O modules. The maximum cable length reaches 5 meters from the main rack. Therefore, you can place this board in a separate enclosure. Typical applications include distributed machine control and remote I/O panels. For distances beyond 5 meters, use an active extension kit.

Maintenance and Module Replacement

Always power down the system before removing any module. Then press the release latch on the target unit. Pull the module straight out from its slot. Insert the new unit until you hear a click. Finally, restore power and verify the Link LED turns solid green.
