Pins table and GPIO connection

GPIO pins table

GPIO are optically isolated MOSFET, working as mechanical relays.

  • GPI 1 and 2 have a common pin.
  • GPO 1, 2, 3 and 4 have a common pin.
  • GPO 5, 6, 7 and 8 have a common pin.

Each GPI can sink a current between 10mA/3V to 45mA/48V.

Each GPO can sink a current of up to 300mA maximum in the closed state and can accept up to 48V in the opened state.

The courant leakage is less than 1μA when opened and the resistance is less than 2 ohms when closed.
