Abstract

2.1 A circuit arrangement comprising an optocoupler which is connected in series with an electronic circuit arrangement at the input terminals of the circuit unit is suitable for the electrically isolated reception of binary electrical signals of different pulse amplitudes. 2.2 To construct such an arrangement as simply as possible, the electronic circuit unit is a series controller (4), the series branch of which is located between one input terminal (1) and the optocoupler (6) and the control input (7) of which is connected via a Zener diode (8) to the other input terminal (2). A constant-current source (13) with voltage-dependent turn-on threshold is arranged between the optocoupler (6) and the other input terminal (2). To reduce the power consumption, a switching device (9) which can be controlled by clock pulses is advantageously connected in parallel with the Zener diode (8). 2.3 The circuit arrangement is suitable for compact input/output devices of electronic measuring and protection devices. <IMAGE>
