Hi everyone, I'm new here and it's been a few years since I worked on a bread board so I'm a bit rusty...
I would like to control an actuator that runs on 24v and reads 24v signals using the PC Parallel Port to send the signals. I don't want to use relays because they are slow. It doesn't matter if the signal wires go to 0v or hi-z for a low; 24v is a hi and a flying lead or 0v is low. I think that it's important to use an optical isolator to keep my PC safe and use a separate power supply; the 24v I can pull from a PC power supply wouldn't be able to power this actuator.
Does anyone know of a schematic or a simple way to go about doing this?
