1. An electronic control board for supplying a control signal to a controlled device in response to a detection signal created by a sensor, comprising:
- a microprocessor;
a power supply section supplying at least one on-board voltage, and a power connector connectable to an external power supply for receiving at least one off-board voltage from said external power supply;
an output jack connectable to a controlled device;
switch means connected between the output jack and the microprocessor, the microprocessor being capable of controlling the switch means to selectively supply an on-board voltage, an off-board voltage or an on-off current path to the output jack.

Abstract
An apparatus and method for controlling plumbing fixtures includes an electronic control board having a microprocessor that accepts four inputs and produces four outputs. Inputs at other than the microprocessor'"'"'s operating voltage are converted thereto. Outputs having different voltages are controlled by latching relays. The control board can be used with a Smart Sink that requires a sequenced hand washing. The control board can form a node on a network that monitors and controls the functions of multiple boards throughout a facility.
