Hi guys
its been 20 + years since my electronics Schooling and use of.
need a control board to control bistable relays, My bms (battery management system) output is 12 v normally and goes to 0v when a fault occurs Which should turn off relay.
bms is designed to control a regular large contactor (100-200 amp)but their coils draw to much current ( .5 to 1.5 amps) for my application.
solid state relays could work but would loose about 1 volt across contacts
any help with a circuit would be greatly appreciated
I included a sketch with as much info I think is needed
regards
have looked on this site and many others and have not found what I need
