“The LK202-24-USB has six general purpose outputs. These are provided to control relays or other electronic devices. This allows external devices to be turned on or off using your PC or controller and software commands. That’s right; you can control everything from case fans to cold cathodes to even your desk lamps! If you’ve followed my article on installing a color video module into your case, you can also use the GPO’s to control that! There are2 types of GPOs on this bad boy, low and high power. GPO 1, 2 and 3 are referred to as Low Power GPOs and are capable of sourcing +5V at 20mA which is limited with a 240 ohm current limiting resistors. GPO 4, 5 and 6 have no current limiting resistors and offer an optional +12V power through the white floppy connecter located bottom left of the display.”
