Multi-connector I/O interface board typically found in Mitsubishi CNC or PLC control units (like BJ or Alpha controllers), used for multiplexed signal routing between CPU backplane and peripheral modules. Model Numbers: BB26A (board assembly), BN634E180H01 (Mitsubishi part code) Board Type: Connector harness / I/O interface PCB Connectors: • (10) DB25 or similar high-density D‑sub female/male connectors (panel-edge mounted) • (2) Modular header connectors (for ribbon cable to main backplane) Mounting: PCB mounted via standoffs/screws inside enclosure Signal Routing: Multi-channel digital or analog I/O lines; likely dual‑redundant or isolated paths per channel Via Count: At least 12 connectors visible, suggesting 100+ signal lines PCB Layers: Multi-layer (approx. 4+ layers) for signal integrity Orientation: Vertical edge-mount connectors; board likely ~300 mm × 200 mm Power: No active components—powered indirectly via connected modules (no onboard regulator) Components: Primarily passive — traces, vias, edge-mounted connectors, few resistors or termination components Labeling: Each connector keyed and silk‑screened with pin numbering Weight: ~0.3–0.4 kg Country of Origin: Japan (Mitsubishi OEM) Main Application: Interface board for routing I/O to CNC/PLC modules; suitable as replacement in Mitsubishi control cabinets requiring BB26A assembly Please review pictures carefully and let us know if you have any questions!
