Power Supply for NU91
External Power Supply – the board can be powered with a +9V ~ +24V external power supply though a DC connector on the back panel. The rear +9V ~ +24V 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 +9V ~ 24V (±5%) and the shell is GND.

Internal Power Supply – the board can alternatively be powered via the internal +9V ~ +24V DC 1 x 2 power connector. The internal 1 x 2 power connector is a Molex 5566-2 header which accepts a Molex 5557-02R connector from the power supply.

Caution: There is no isolation circuitry between the external +9V ~ +24V DC jack and the internal 1 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 +9V ~ +24V DC jack is covered if the internal 1 x 2 power connector is to be used.
