Abstract: An aim of an embodiment of the invention is to couple load feeders to back plane buses without the danger of the junctions being damaged. For this purpose, a back plane bus module is provided with a coupling element, especially a BUS-ASIC with which a point-to-point communication link to the automation device or the load feeder can be established. An optical interface is connected to the BUS-ASIC and is used to establish communication to a load feeder by an optical coupling. The optical coupling can for example prevent plug connections from being damaged when the load feeder is coupled thereto and at the same time provide for galvanic separation.

Abstract: The invention relates to a measured value acquisition and processing unit (5) that facilitates the acquisition and processing of very small measuring signals in the range of interfering signals, such as, for example, noise, spillovers, etc. This means that the useful values to be detected usually contain interfering portions. The inventive measured value acquisition and processing unit (5) separately acquires these interfering portions by means of a switch element (10) disposed in the area of feed of the measured signals by means of which the measuring circuit is short-circuited in such a manner that the measured signal is not coupled in but only interfering signals that might occur in the measuring circuit are detected. The inventive method provides a large range of dynamic ratio for the detection of measured values at low costs.

Abstract: The invention relates to an electricity meter with signal channels that are passed to a digital signal processing device and each of which has a multiplexer with downstream analog/digital converter. Voltage signals of an electrical consumer can be connected to a first input of the analog/digital converter of the first signal channel, and current signals of the electrical consumer can be connected to a first input of the analog/digital converter of the second signal channel. In order to allow the meter to be used without any circuit variation both as a four-conductor meter and as a three-conductor meter, one of the voltage signals can be connected to a second input of the analog/digital converter of the first signal channel.

In order to compensate for external angle errors, different waiting cycles are generated between the current and voltage values in the digital signal. A measuring device and a method are provided for this purpose. A preferred application is in electricity meters.

Abstract: An electronic measuring device achieves an improvement in measurement accuracy while at the same time compensating for influences on the measurements, by providing for a correction factor to be stored in a correction element when the measuring device is first set up. During operation, provision is made for a test voltage to be received and compared with a reference value stored during setting. If there is a difference between the two values, a new correction factor is produced which compensates for any measurement signal effect. The measuring device is particularly suitable for electricity meters.
