    • Fast detection of contact status with an AC wetting voltage using a ratiometric approach is described herein. In one embodiment, a voltage source wets the contact with a wetting voltage. A contact voltage monitor receives voltage obtained from the contact and converts the voltage to a first frequency output. A wetting voltage monitor receives wetting voltage provided from the voltage source to the contact and converts the sensed wetting voltage to a second frequency output. A processor generates a ratio between the first frequency output and the second frequency output and determines the status of the contact and the field wires associated with the contact in accordance with the generated ratio.
    • 本文描述了使用比例法进行AC润湿电压的接触状态的快速检测。 在一个实施例中,电压源使接触件湿润润湿电压。 接触电压监视器接收从触点获得的电压,并将电压转换为第一频率输出。 润湿电压监测器接收从电压源提供给接触器的润湿电压,并将感测到的润湿电压转换为第二频率输出。 处理器产生第一频率输出和第二频率输出之间的比率,并且根据所产生的比率确定接触状态和与触点相关联的场线。

    • A redundant control system for controlling an electromechanical system is provided. The control system includes a first processor, a second processor, an input-output node, a first communication channel, a second communication channel, and a signal selector. The first and second processors have a control algorithm and state variables resident thereon. The first and second processors each generate an output signal based on the control algorithm, the state variables, and an input signal from the electromechanical system. The first communication channel communicates the input signal and the output signal between the first processor and the input-output node, while the second communication channel communicates the input signal and the output signal between the second processor and the input-output node. The signal selector communicates either the output signal from the first processor or the output signal from the second processor to the electromechanical system.
