(Case No. 8254) ABSTRACT OF THE DISCLOSURE An electronic bipolar interface driver circuit for interconnecting a microprocessor to an electromagnetic relay load. The driver circuit includes a peripheral adapter circuit having a pair of outputs connected to a respective one of the two inputs of a pair of NAND gates. A source of square-wave signals connected to the other inputs of the two input NAND gates so that a.c. signals are supplied to one of two switching amplifiers. The a.c. signals are transformer-coupled to a pair of rectifiers. The rectified d.c. voltage is supplied to either one of two switching transistors which establishes a given polarity of voltage on a pair of output terminals and which illuminates one of two optical couplers to feedback a checking signal to the peripheral adapter circuit to verify the polarity of the voltage on the output terminals.
