Voltage protection arrangement for an electronic device

Abstract: The invention relates to a voltage protection arrangement for an electronic device, in particular for a control system in automation engineering. The voltage protection arrangement has a greater functionality, and therefore also a greater range of applications, due to the fact that said arrangment has a switching-off unit (2) and a voltage detection unit (4) connected to the output (3) of the switching-off unit (2), wherein the switching-off unit (2) has a voltage comparator (7) and a normally electrically closed switch (10) connected to the output (8) of the voltage comparator (7), arranged between the input (9) and the output (3) of the switching-off unit (2), wherein the voltage detection unit (4) has a voltage comparator (12) and a switch output (14) connected to the output (13) of the voltage comparator (12) for signalling an impermissible voltage, and wherein, in the event of an impermissible voltage Ui occurring at the input (9) of the switching-off unit (2), the electrical switch (10) is opened and, in the event of a subsequent permissible voltage U2 occurring, the switch (10) is closed again.

Method and system for the transmission of cyclic and acyclic data

Abstract: One aim of the invention is to create a way to transmit data via a transmission channel which effectively counteracts previously known drawbacks resulting from a ring structure and a line structure while combining advantages of one topology group with advantages of the other topology group. Said aim is achieved by a method for transmitting cyclic and acyclic data between at least two user units that are connected to a transmission channel via said transmission channel, protocol-specific cyclic data being transmitted between at least one user unit acting as a master and at least one user unit acting as a slave. The inventive method is characterized in that data that is to be transmitted during an imminent transmission cycle is checked for redundancy and timeliness relative to corresponding data of a previous cycle while acyclic data is inserted in the data area provided for redundant data instead of said redundant data if an imminent transmission cycle is identified for which redundant data having no new information content is provided.

Electrical connecting device

Abstract: An electrical connecting device with a housing, with terminals for insulated conductors, with at least one conductor bar, with at least two actuating elements and with at least two insulation piercing elements, the actuating elements being arranged to be able to turn relative to the insulation piercing elements and each having a conductor receiver for the conductors to be connected. The insulation piercing elements establish electrical contact of a conductor which has been inserted into the conductor receiver to the conductor bar, when the actuating element is pivoted out of a first position, in which the conductor can be inserted into the conductor receiver into a second position. By the conductor receiver being able to have at least two insulated conductors can be inserted therein, the possible applications are further enhanced, and the dimensions of the connecting device can be as small as possible.

Spring force clamp, has clamping side piece attached to retaining side piece by using bending joint, and operating side piece arranged at clamping side piece, where area subjected by opener is arranged at operating side piece

Abstract: The clamp has a leg spring (4) with a fixed retaining side piece (5) and a clamping side piece (6) attached to the retaining side piece by using a bending joint. The clamping side piece is located at a pointed angle with the retaining side piece. An opener (8) subjects an area inclined in an operating direction of the clamping side piece to pivot the clamping side piece in a direction of a clamping counter bearing. An operating side piece (7) is arranged at the clamping side piece, where the area subjected by the opener is arranged at the operating side piece.

Electrical printed circuit board and housing connector, has coding and positioning unit arranged between contact units and connectable with printed circuit board, and coding arms, where one arm is engaged and mounted in opening of housing

Abstract: The connector has a single piece housing (2), which is designed as a socket and connector part (3). A coding and positioning unit (6) is arranged between contact units in the connector part and is connectable with a printed circuit board (10). The housing has an opening to admit the coding and positioning unit. Coding arms are arranged at the coding and positioning unit, where one of the arms is engaged and mounted in the opening.
