Abstract: Circuit configuration for error reporting, having a signal transmitter (1) for issuing error signals, having an error reporting line (46) that is connected with an error report evaluation device (6), having a coupler (2) for galvanic separation of the error reporting line (46) from the signal transmitter (1), and having a power supply (5) for making available an operating voltage for the coupler (2). A connection circuit (3) is provided between coupler (2) and error reporting line (46), which places the error reporting line (46) at a predetermined potential, the error report potential, if the operating voltage of the coupler (2) is insufficient. The connection circuit (3) can furthermore be controlled by the coupler (2), in such a manner that if the signal transmitter (1) issues an error signal, the connection circuit (3) places the error signal onto the error reporting line (46).

Abstract: The inventions herein include a measuring transducer, having a first transmission channel which conditions an analogue measurement input signal in an analogue manner and makes it available as a conditioned measurement signal. In addition, the measuring transducer may have a second transmission channel which conditions the analogue measurement input signal and makes it available as an influencing signal, wherein the conditioned measurement signal and the influencing signal are combined and made available as a measurement output signal. In a further embodiment of the inventions herein, a measuring system has a temperature sensor and a measuring transducer according to the present innovations.

Abstract: In a method for determining a frequency of an input signal, a first count value is determined by counting clock edges of a reference clock signal while the input signal corresponds to a first level value. Further, a second count value is determined by counting clock edges of the reference clock signal while the input signal corresponds to a second level value. The frequency of the input signal is determined as a function of the first and the second count value.

Abstract: Safety relay circuit, in particular, comprising two series-connected or parallel-connected relay switches (k1, k2) in a load current circuit (LN). The relay switch (k1) is assigned a switch position indicator circuit (A1). An evaluation circuit compares the command input to the relay (k1) with the display of the indicator circuit (A1), so that any fault states that may occur at the relay switches can be detected.
