  • Patent number: 8793001
    Abstract: The invention relates to a method for monitoring an output driver that can be parameterized and is suitable for controlling actuators in industrial automation technology, for applying analog signals to an output channel, with the following steps: determining resulting internal leakage power based on the parameterization data provided for parameterizing the output driver, comparing the leakage power relative to a leakage power limiting value, and, dependent functionally on the comparison result, stopping the application of an analog signal on the output channel corresponding to the parameterization data provided for parameterizing the output driver. The invention further relates to an analog signal output device, suitable for controlling actuators in industrial automation technology and in accordance with the aforementioned method, comprising at least one output driver and a monitoring device.

  • Patent number: 7865648
    Abstract: The invention pertains to a modular data transmission system with several modules or bus nodes that can be arranged adjacent to one another in a row. The data transmission system comprises a first bus node that features a first transmitter for the wireless transmission of data and an electrical connector, as well as a second bus node that features a first receiver for the wireless reception of data and an electrical connector. Both bus nodes are detachably fixed on a mounting rail such that they are arranged adjacent to one another in a row. The first and second bus nodes are respectively detachably connected to a bus receptacle, wherein each bus receptacle features an electrical mating connector that is coupled to the electrical connector of the respective bus node in the connected state in order to transmit energy, as well as a positioning device for positioning the respective bus node.

  • Patent number: 7704079
    Abstract: The invention describes a T-shaped bus connector comprising a holding device for mechanically retaining the T-shaped bus connector on a mounting device on which the T-shaped bus connector is to be arranged, and further comprises a first and a second connecting unit for respectively producing an electrical connection to a complementary connecting unit of a device arranged adjacent to the bus connector, wherein the first and second connecting units face in substantially opposing directions and are constructed complementarily to one another, as well as a third connecting unit, oriented substantially perpendicular to the first and second connecting units, for producing an electrical connection to a connecting unit, complementary to the third connecting unit, of an electrical or electronic module, wherein data and/or power bus lines are run between all three connecting units, and all three connecting units are covered at least in part with a shielding material.

  • Patent number: 6572942
    Abstract: Antistatic fabric for flexible containers for bulk material that includes electrically non-conducting threads and static dissipative, special permanent antistatic threads. The static dissipative, special permanent antistatic threads are made of a thermoplastic synthetic with an additive mixed in that increases the conductivity. The static dissipative, special permanent antistatic thread is shaped like a small band or tape with an approximately rectangular cross-section or a multifilament of very thin filaments.
