Power Supply for LI1U-20
External Power Supply – the board can be powered with a +12V ~ +28V external power supply though a DC connector on the back panel. The rear +12V ~ +28V DC jack accepts plugs with an inner diameter (ID) of 2.5 mm and an outer diameter (OD) of 5.5 mm, where the inner contact is +12V ~ +28V and the shell is GND.

Internal Power Supply – the board can alternatively be powered via the internal +12V ~ +28V DC 2 x 2 power connector, where pins 1 and 2 are GND and pins 3 and 4 are +12V ~ +28V (±5%) DC. The connector used is Molex Micro-Fit (3mm pitch), right-angled, 4-pos/dual row (2x2).

Caution: There is no isolation circuitry between the external +12V ~ +28V DC jack and the internal 2 x 2 power connector. It is the system integrator's responsibility to ensure no more than one power supply unit is or can be attached to the board at any time and to ensure the external +12V ~ +28V DC jack is covered if the internal 2 x 2 power connector is to be used.
