P-Q Controls M519-02 Valve Drive Board
 |
The P‑Q Controls M519‑02 is a PWM valve drive board that accepts analog command signals and outputs proportional current to actuate hydraulic or electro‑hydraulic valves. Common failure points on this class of boards include burned fuses or protection relays, damaged MOSFETs or driver ICs, degraded input/output connectors, and overheating of the power stage due to inadequate cooling or excessive load. Initial troubleshooting should verify that the board receives its rated supply voltage (typically 10‑30 VDC), check for continuity and proper operation of the PWM output drivers, inspect for visible burn marks or loose solder joints, and review any diagnostic LEDs or error codes displayed on the unit’s panel.[oss-gpt-20b] |
