DC Terminal Block Power

The DC Terminal Block Power option is for units where a customer supplied external regulated power supply is used to power the board.  The terminal block allows easy connection to the wires from the power supply and includes reverse voltage protection in case the wires are installed backwards.

This type of connection is typically used when a power supply is already available, or when daisy chaining multiple boards together, or when mounting more than one in an enclosure to save space.
