ABSTRACT:
An opto-electronic coupler for signal voltages of <1 V is provided in which the transmitter of the coupler is electrically separated from the receiver. In order to avoid a current supply device, there are provided two additional couplers connected in series and of opposite coupling direction to the first coupler. The additional couplers supply the necessary energy for a luminescent diode transmitter of the first coupler.
