  • Loads for the buffered outputs should be switched on the ground side, i.e. 12/24V (from supply) -> load -> output terminal -> ground (from supply)
  • The relay can tolerate up to 2A each and should be switched on the high side
  • The sinking outputs can sink a maximum 500mA total across the 3 outputs, so if you use a single channel you can sink the whole 500mA across it.
  • Do not use to switch mains voltages!
