25mA to 100mA
hi,
i need to raise the current output of a 12v 25mA trigger to 12v 100mA to drive a relay. i found a few sites showing a circuit using a transistor to accomplish this but im having a hard time understanding the schematics. i also read that i may be able to use a low current relay thatll be driven by the trigger i have along with a seperate 12v 100mA power supply to drive the higher current relay, i just cant seem to find such a relay. my trigger is a denon home theater receiver and the relay is part of a da-lite motorized screen. any help is greatly appreciated.
