All inputs are activated from a positive voltage relative to battery negative over the 6.0 Vdc to
30.0 Vdc range. All outputs are delivered from a low-side switch, which requires that the device
under control be connected from an output terminal to B12. Figure 2-9 shows the generic
interface wiring for this board.
