Hi. I need your help on the subject of controlling a 12v linear actuator. I have a 4 channel Smart 12v module, which I am currently using to start the pump at a given time - here it is so simple that the relay short circuits the contact and the function is simply on/off. With an actuator, I need to open it at a given time and close it at another, so there must be a polarity change. Please tell me how to do this in the simplest way. I don't want to overcomplicate things. Please find attached pictures of the components. Thank you in advance.
