To all of the electronics guys out there, I have a question. Can an optocoupler be used to directly close the shutter wires for the camera? I had been using a darlington array driver attached to the coil of the relay and the camera leads across the N.O. pins of the relay. I was wondering if I could just directly connect the output port of my controller to the input of the optocoupler and then the camera wires across the output of the coupler. I was not sure how much current capacity was needed, but I figured it would not be much since the shutter wires have only 3 volts between them. Any thoughts?
