Tokheim Automation PCA 3-0459-011 board

The Tokheim Automation PCA 3‑0459‑011 is a power‑control board used in industrial dispensing and control systems, typically driving solenoids or motor actuators via solid‑state relays. Common failure modes for this class of boards include burnt or tripped MOSFETs/IGBTs, damaged gate drivers, degraded capacitors on the high‑voltage side, and shorted protection diodes. First‑check diagnostics: verify that the board receives its rated input voltage and ground reference; inspect all power components (capacitors, resistors, transistors) for visual signs of damage or overheating; and read any diagnostic LEDs or error codes from the host controller to pinpoint a specific fault.[oss-gpt-20b] Post Comment
