    摘要： Disclosed herein is a controller and method useful for transferring control of a process control device between first and second control modes. The controller includes first and second servo control modules that generate first and second drive signals based on feedback information from first and second sensors for control of the process control device in accordance with first and second control modes, respectively. The controller also includes a feedback control transfer module that transfers control of the operation of the process control device from the first control mode to the second control mode based on the feedback information from the first sensor. In certain embodiments, such control transfer involves a control routine that initially generates the second drive signal based on the first drive signal to effectuate a smooth, bumpless transfer between the control modes.

    摘要： A non-contacting position sensor having primary and secondary sensors detects relative displacement between two objects. The secondary sensor may function as a limit switch detection element in a limit switch circuit, and is positioned to be in the path of magnetic flux not detected by the primary sensor. The primary sensor is positioned in a flux path between sections of a flux gathering pole. A secondary sensor is positioned in a leakage flux path outside the first sensor or may be positioned in a secondary flux path.

    摘要： An opto-isolator multi-voltage detection circuit is capable to handle a wide range of input voltages ranging from about 9 volts DC to about 240 volts AC includes an input voltage, an opto-isolator, a rectifier, a voltage divider, first and second transistors, and a DC to DC converter. The voltage divider operatively coupled to the first and second transistors is capable of evenly dividing the input voltage across the first and second transistors. The DC to DC converter operatively coupled to the transistors, the voltage divider, and the opto- isolator is capable of maintaining an output current from the rectifier. The use of the DC to DC converter, the voltage divider, and the transistors provide benefit of reducing a power dissipated throughout the entire circuit.
