Single input, single supply three-state controller. |
摘要 |
A circuit for controlling three modes of operation of a multiple terminal load using a single positive DC voltage 12, simple circuitry, two relays 26, 30 and a single input control line 17. The circuit senses a switch 16, or logic device generating three conditions: open circuit, connection to positive voltage or connection to ground. Three operating modes are effected while minimizing the number of wires needed to control the multiple terminal load. |
