Hello
I want to use an optocoupler to switch on a piece of muscle wire and would like to check whether this is a sensible idea.
The muscle wire has a resistance of 20 ohm and I am using a 12V supply (so the current will be 0.6A). It's being powered by 8 AA cells which can deliver this current.
I want to switch it on using a remote control module that runs on 4.5 - 7V and has an output pin that goes high when activated.
I could use a transistor and a relay but I don't want to have a relay because I want it to run silently. Is an optocoupler a viable alternative? If so what else do I need to make this work?
Many thanks
