摘要： A switching circuit for selectively coupling a load to an A.C. power source is disclosed. The switching circuit includes a diode-commutated master relay contact and a pilot relay contact coupled in series therewith. The master and pilot relay contacts are coupled between a load and the power source in such a manner that power is applied to the load whenever both the master and pilot relay contacts are closed. A timing and control circuit performs a switching operation to open the master relay contact during a first half-cycle of the A.C. waveform of the power source during which the commutating diode is forward-biased. The pilot relay contact changes state during the next half-cycle of the A.C. waveform and the master relay contact is reclosed during the following half-cycle of the A.C. waveform.

摘要： A machine controller having start and time delay functions activated and set by a single switch. There is a cycler for activating and deactivating machine functions in a timed sequence. There is a manually operable start/delay-set switch and an electronic circuit responsive to the switch which produces a start signal upon initial closing of the switch, and which produces a delay signal after the switch is held closed for a predetermined time. An electronic control circuit responds to the start and delay signals to store a delay time and activate the cycler after the stored delay time has expired.

摘要： Noise immunity is enhanced in a digital computer controlled process by phase-shifting input signals before they are sampled by the computer to remove high frequency noise using small filters having short time constants, by sensing the phase-shifted signals when they are near their peak amplitudes, which is arranged to occur when line voltage is not at its peak amplitude, then processing the sensed signals and transmitting command signals either the first or a subsequent time after such sensing that the line voltage passes through zero.

摘要： A control system and method obtain a stress profile of a device disposed onboard industrial equipment. The stress profile represents a stress characteristic of the device over time during operation of the industrial equipment. The system and method determine a smooth zero crossing function based on the stress profile. The smooth zero crossing function includes spikes that represent reversals of the stress characteristic. The system and method generate a control signal based on the smooth zero crossing function.

摘要： The invention disclosed is useful in an I/O system of a programmable controller and provides a method and circuitry by which control and diagnostic information is exchanged between a control unit of an I/O module and a plurality of input/output points of the I/O module. A control signal is generated in the control unit in the form of sequential pulse frames such that the control information is defined by a series of pulse width modulated pulses. Each frame includes a no-pulse time period following the review of pulses to mark the end of a frame. Each I/O point receives a control signal of its own and generates a clock pulse in response to each pulse. The clock pulse initiates a sampling of the corresponding pulse and simultaneously initiates return of a diagnostic signal value to the central unit by implementation of firmware in a switch processor. Thus, the control signal provides for sampling of its own content and provides for a return of a diagnostic data bit for each control bit.

摘要： A controller area network (CAN) has a plurality of nodes connected to transmit and receive data over a serial data line. An AC power source is also connected to each node. Each node senses the AC power waveform and synchronizes bit transmission and bit detection with the waveform. In a preferred embodiment, each node includes a circuit that detects zero crossings by the AC waveform, providing two accurately synchronized bit intervals per complete AC cycle. A preferred version of the invention includes hardware and software that detects miswires of the node to the data and power lines.
