Abstract: An electrical insulation circuit of the type connected between a peripheral circuit and a two-way bus. The electrical insulation circuit includes first and second optocouplers for transmitting differential signals in the peripheral circuit-to-bus direction, and third and fourth optocouplers for transmitting differential signals in the bus-to-peripheral circuit direction. The first and third optocouplers are associated with a first signal terminal on the peripheral circuit side and with a first data wire on the bus side, and the second and fourth optocouplers are associated with a second signal terminal on the peripheral circuit side and with a second data wire on the bus side. Further, the first and third optocouplers and the second and fourth optocouplers are connected such that the first and second optocouplers are off during transmission in the bus-to-peripheral circuit direction and the third and fourth optocouplers are off during transmission in the peripheral circuit-to-bus direction.
