The invention provides an electromagnetic interference isolation circuit device for an unmanned aerial vehicle. The electromagnetic interference isolation circuit device comprises a first resistor, asecond resistor, a third resistor, a fourth resistor, a fifth resistor, a matched first light emitter, a first light receiver, a matched second light emitter and a second light receiver. Two optocoupler devices are constituted correspondingly by the first light emitter, the first light receiver, the second light emitter and the second light receiver, and are basic design optocoupler circuits, anda flight control circuit and a CDI circuit are divided into two independent loops, thereby avoiding the direct interference of a pulse signal of a CDI module to the flight control circuit. 本发明提供了种用于无人机的电磁干扰隔离电路装置，包括：第电阻、第二电阻、第三电阻、第四电阻、第五电阻、相匹配的第发光器、第受光器和相匹配的第二发光器、第二受光器。本发明中通过第发光器、第受光器、第二发光器、第二受光器对应构成两个光耦器件，并其两个光耦器件为基础设计光耦电路，将飞行控制电路与CDI电路分成两个独立回路，避免了CDI模块的脉冲信号直接对飞行控制电路造成干扰。
