Update – I believe the relay terminal I am looking for is Digi-Key ED2581-ND. The only limitation I see on enabling all solenoids at once could be the primate 2 amp fuse. Solenoid inrush information varies from 410mA to 800mA with holding current from 80 mA to 240mA. If I stagger the turn on by some time and the holding is really only 240, I will be OK, but not much margin for running the BeagleBone. I’m placing an order for the terminal block and case, and I would like to have a few spare fuses on hand. The parts list doesn’t list a part number. Anyone know fuse part number?
