Abstract
A turbine engine over-temperature shut-off control circuit includes a series of separate timing circuits and output control signal generation gates. A corresponding set of temperature set-point triggering comparator circuits apply energization signals to their associated timing circuits and gates, to define a temperature vs. time envelope, which turns the turbine off when the turbine has been at a predetermined dangerously high temperature for more than a predetermined length of time.
