ABSTRACT:
A brake interface module for an electronic air brake (EAB) or a magnet valve that incorporates positive train control digital commands with additional fail-safe, discrete train control spare inputs into a single, fail safe output via redundant power supplies. The brake interface module comprises a positive train control circuitry including a first microcontroller and a second microcontroller operatively coupled to each other. The brake interface module also includes spare discrete inputs that utilize fail-safe principles and are continuously monitored by the second microcontroller to achieve fail-safe performance. Each power supply contains redundant, independent means of shutting down to facilitate self test.
