から得るようにした信号絶縁装置。[Claims for Utility Model Registration] A pulse transformer having a primary coil and a secondary coil with a center tap; circuit means driven by a large output clock, a common line connected to the center tap of the pulse transformer, and a voltage obtained by rectifying the signal generated in one of the secondary coils with this common line as a reference. an open collector transistor whose emitter is connected to the common line, a pair of terminals each connected to the emitter and collector of this transistor, and the other secondary coil with the common line as a reference. and a circuit that rectifies and smoothes the generated signal and applies it to one of the pair of terminals, and in an input circuit mode, the pulse transformer is driven by an input clock and the status signal applied to the pair of terminals is sent to the primary coil. The signal isolating device reads the signal at one end of the primary coil, drives the pulse transformer by an output clock in an output circuit mode, and obtains a status signal to be applied to the primary coil from the pair of terminals.
