Nissei N9POS-20 Circuit Board

The Nissei N9POS‑20 is a control board used in 120 ton injection molding machines, handling motor drives, sensor inputs and PLC logic. Common failure points on this class of boards include burnt or tripped MOSFETs/IGBTs in the power stage, degraded capacitors on the high‑current rail, and damaged I/O traces from vibration or thermal cycling. First‑check diagnostics: verify that the 48 V DC supply is within spec and stable; inspect all connectors for corrosion or loose pins; visually examine the board for burn marks, cracked solder joints, or swollen electrolytics before proceeding to component testing.[oss-gpt-20b]
