  • Patent number: 9857781
    Abstract: An output module for an industrial controller configurable to simplify setup and commissioning is disclosed. The output module includes configurable PWM outputs that may be scheduled to start at different times within the PWM period, that may be configured to generate a fixed number of PWM pulses, and that may have an extendable PWM period. The output terminals are configurable to enter a first state upon generation of a fault and further configurable to enter a second state after a configurable time delay following the fault being generated. The output module may receive inputs signals directly from another module and set output signals at the terminals responsive to these signals.

  • Patent number: 9735777
    Abstract: A method is provided for safely switching off a photovoltaic module comprising solar cell groups, a first conductor electrically connected to the solar cell groups, and a second conductor electrically connected to the solar cell groups. The safety device comprises at least one first safely switching element and one second safety switching element, wherein the safety switching elements are arranged in parallel across the solar cell groups and are connected to the first conductor and the second conductor in an electrically conductive manner. If an error state occurs, at least one of the safety switching elements is switched by means of a switching process, such that a shorted circuit is produced across the solar cell groups. The at least two safety switching elements perform the switching process in working areas that differ at least partially regarding the temperature.

  • Patent number: 9557720
    Abstract: An electrical power distribution system comprises recloser monitors that monitor power line voltages to thereby whether reclosers are open or closed. The recloser monitors report the voltages and associated times to a remote recipient, such as by cell phone. Momentary voltage drops that do not result in a power outage are reported as well. At least some of the recloser monitors are carried by power poles and desirably comprise weather stations for reporting localized weather conditions. The overall efficiency and reliability of the power distribution system is improved by allowing for more rapid identification of outage locations and proactive repair of power system components prior to actual outages.
