boardhead 3 Posted January 12, 2022 After replacing three 16 channel Sainsmart solenoid boards that had single relay failures, I replaced them with four RGB W four channel 24 amp mosfet based LED drivers. Had to replace the 7 amp +12vdc power supply with a 30 amp unit as mosfet's require more power. Three run the 12vdc toys, and one operates the chime unit and knocker at 24vdc. Link to comment
