Abstract
A vital relay driver whose response time can be readily controlled such that the release time of the relay may be varied, yet may be held to very close tolerances. The vital relay driver is controlled by a microprocessor dedicated to this function, such processor generating a dynamic signal of fixed frequency in dependence on a cycle number which is continually replenished; otherwise the microprocessor stops producing the dynamic signal and the relay is released in a closely known time.
