• BB: Backplane / Base Board (CPU rack)

• 03: Revision 03 (hardware version)

• Alias: JANCDBB03, DF8203303-A0 (Rev. A0)

Specifications

Electrical

• Power: 24 V DC ±10%

• Bus: XRC/NX100 backplane bus, multi‑slot interface

• Material: FR‑4 (industrial grade)

Mechanical & Environmental

• Dimensions (L×W×H): 440 × 400 × 40 mm

• Weight: ~1.8 kg

• Mounting: Rack/chassis mount (CPU rack)

• Operating Temp: 0 °C to +40 °C

Key Functions

• Main Backplane: Connects all controller boards (CPU, I/O, servo, network) in the CPU rack.

• Power Distribution: Distributes 24 V DC to plug‑in modules with onboard fusing.

• Signal Routing: High‑speed bus signals between main CPU and peripherals.

• Slot Expansion: Provides multiple slots for I/O and communication expansion.

• System Integrity: Ensures noise isolation and stable system‑wide communication.

Applications

• Motoman Robot Controllers: XRC (welding, handling, assembly) and NX100 series.

• Yaskawa CNC: YASNAC i80/i90 and legacy systems.

• Industrial Automation: Replacement/retrofit for aging production lines.

Compatibility & Notes

• Fits XRC / NX100 controller racks only; not interchangeable with JANCD‑B or other backplanes.

• Drop‑in replacement for DF8203303‑A0 Rev.A0 (no wiring changes).

• Maintain cabinet ventilation (0–40 °C) to avoid overheating。
