Komatsu PC.100.120 7824-30-1100 controller
 |
The Komatsu PC.100/PC.120 7824‑30‑1100 is an ECU controller module used in mid‑size excavators, handling power distribution and signal processing for hydraulic and electrical systems. Common failure points on this class of units include burnt or failed MOSFETs in the power stage, damaged capacitors or inductors due to voltage spikes, and connector corrosion leading to intermittent I/O faults. First‑check diagnostics should verify proper 24 V DC input, inspect all solder joints and component values for signs of overheating, and review any fault codes displayed on the excavator’s diagnostic panel before proceeding with module replacement.[oss-gpt-20b] |
