MIL-PRF-28776H规定了使用固态电路输入元件组合的继电器的一般要求，该元件与执行与控制系统应用相关的开关功能的机电继电器一起工作（见6.1）。这些继电器设计用于低功率和中功率开关电路，触点额定值高达1安培交流电（ac）或直流电（dc）。根据+125？的100000次循环，在90%的合格置信度和60%的合格维护置信度下确定故障率水平？！C在本文规定的额定负载条件下。不包括延时继电器。 警告:使用任何低于额定线圈电压的线圈电压都会影响继电器的运行。警告:拾取、保持和退出电压仅用于测试目的，不得用作设计标准。有关其他应用和警告信息，请参见6.1。

MIL-PRF-28776H establishes the general requirements for relays that use a combination of solid state circuit input elements functioning with an electro-mechanical relay that performs the switching functions associated with control system applications (see 6.1). These relays are designed to operate in low and medium power switching circuits with contact ratings up to 1 ampere alternating current (ac) or direct current (dc). The failure rate level is established at a confidence level of 90 percent for qualification and 60 percent for maintenance of qualification based on 100,000 cycles at +125?!C under rated load conditions specified herein. Excludes time delay relays. CAUTION: The use of any coil voltage less than the rated coil voltage will compromise the operation of the relay. CAUTION: Pick-up, hold, and dropout voltages are for test purposes only and are not to be used as design criteria. For additional application and caution information, see 6.1.
