Hi, here it is. This is a much simplified schematic of a section of a wood routing machine I'm making. The diagram supplied relates to the side feed assembly - there are two actuators, so a total of 6 relays used. Ideally I'd like to be able to activate all 6 at once. I'm disabling the motor then using a delay before switching polarity, then a further delay before enabling again - as a means of protecting against short circuiting. Thanks for your advice re the solid state relays. I'm actually using an L298N controlling two actuators to raise/lower the height of a router tray. I could maybe use another of these for the side feed motors in place of the relay arrangement I have? (my reason for using the relays was to avoid the 2v voltage drop from the L298N) Cheers.
