Went to commission an industrial ventilation fan this afternoon that has a 0-10V speed control and found that the fan unit has and requires its own source for the 10V control, ready to be connected to a potentiometer. I am looking to connect it to either a micrologix analogue output module or Weidmuller TCP MODBus analogue controller which are both source units too.
Being a man of the digital age, this analogue interfacing has me scratching my head.
Can anyone recommend an isolation unit or digital potentiometer or a clearer mind than mind on how to interface this system?
