Hello,
I am not sure if this is the best place to ask but I don't know anyone locally to ask this question.
I have a device (EVVA EMZY motorized lock) which has an open collector output described as "max 12V / 300 mA" which I would like to connect to one of the LogicMachine Reactor inputs. The ampere rating is fine but LogciMachine is 24V and this device clearly expects 12V max.
I have tried reading up on open collectors, etc. but I really lack the basic electrical engineering knowledge to even understand most of what I can find about this. I think I need a pull up resistor and probably an optocoupler or a transistor to convert the voltage, but that is about it.
I tried to ask for someone around here who can design this for me but so far no luck. I am really reluctant to just try something, considering both LM and the lock are pretty expensive.
Any ideas? I am sure it is a really simple job for someone who knows what they are doing but that is not me...
