Patent ID: 7472011

Claim:
A brake interface module for an electronic air brake (EAB) and a magnet valve comprising: a) a positive train control circuitry comprising: i) a first microcontroller with at least one input and at least one output; and ii) a second microcontroller with at least one input and at least one output, the second microcontroller operatively coupled to the first microcontroller; b) an AND gate with a first input, a second input and an output, the first input operatively coupled to an output of the first microcontroller and the second input operatively coupled to an output of the second microcontroller; c) a first power supply operatively coupled to an output of the AND gate; and d) a second power supply operatively coupled to an output of the AND gate, wherein the positive train control circuitry allows for switching between the first power supply and the second power supply to insure a correct voltage for proper operation of both the EAB and magnet valve.
