摘要（英）：

The utility model provides a fault safety dynamic logic and drive circuit which includes a first dynamic pulse circuit, a second dynamic pulse circuit, and a relay. Dynamic signal input terminals of the first dynamic pulse circuit and the second dynamic pulse circuit receive signals. An external power supply positive access point and an external power supply negative access point of the first dynamic pulse circuit are connected with an external power supply. Two output terminals of the first dynamic pulse circuit are connected with two terminals of a coil of the relay. A group of normally open contacts of the relay are connected with an external power supply positive access point and an external power supply negative access point of the second dynamic pulse circuit respectively. The fault safety dynamic logic and drive circuit has the advantages of scientific design, high safety and reliability, small volume, and simple circuit structure, and can realize the device microelectronization.
