    • A low-cost, two-wire, half-duplex high speed powered communications bus having a master/controller and one or more slave/sensor/interface units. The master/controller may have a current-limited power supply, and receive/transmit circuitry. Each slave/sensor/interface may have polarity protection and also have receive/transmit circuitry. The power supply may provide high/low voltage levels on the bus and over-current protection, and have one or more diodes for mis-wire protection. Each transmit circuit may have a tunable R-C network for limiting RF emissions. Each slave/sensor/interface may receive data and power over the two-wire bus.

    • A relay driver circuit which protects a relay against contact degradation. A detector circuit within the relay driver circuit receives an AC signal at a random phase. The detector circuit correspondingly provides a detector signal to a threshold responsive circuit, such as a timer, which drives the relay. The threshold responsive circuit responds substantially the same to a detector signal provided on a positive cycle and to a detector signal provided on a negative cycle. The relay driver circuit is applied to control a blower fan in an air conditioning system.
    • 继电器驱动器电路,用于保护继电器免受接触退化。 继电器驱动电路内的检测器电路以随机相位接收AC信号。 检测器电路相应地向诸如驱动继电器的定时器的阈值响应电路提供检测器信号。 阈值响应电路基本上对在正周期上提供的检测器信号和在负周期上提供的检测器信号进行响应。 继电器驱动电路用于控制空调系统中的风机。
