Fuji Electric UMI5A-C CIRCUIT BOARD

The Fuji UMI5A‑C is a processor card used in Fuji Electric PLCs and motion‑control systems, typically mounted on industrial automation boards. Common failures for this model include burned or tripped 24 V relays, damaged ICs from overvoltage, and solder joint fatigue leading to intermittent communication. First‑check steps: verify the 24 V DC supply rail with a multimeter, inspect all relay contacts and solder joints for cracks or discoloration, and review any logged PLC error codes for communication or I/O faults.[oss-gpt-20b]
