Abstract

PURPOSE:To confirm simultaneously or independently the working of a driver and a power output element with use of inexpensive parts, by inserting a diode between the working confirming circuits provided between the driver and power output element of an output circuit. CONSTITUTION:Power output elements RY0-RY3 of relay constitution are driven by drivers Dr0-Dr3 and with the driving command given from a register G that stores an output data. A driver working confirming circuit consisting of dissidence detecting circuits EOR0-EOR3, inverters INV0-INV3, resistances R0-R3, R10- R13 and R20-R23 plus diodes BD0-BD3 and a power output element working confirming circuit consisting of inverters INV10-INV13 and resistances R30-R33, R40-R43, R50-R53 and R70-R73 are provided along with a basic circuit. Then diodes BD10-BD13 are installed between both the confirming circuits in such way that the working of the driver confirming circuit does not affect the working of the power output element confirming circuit. In such constitution, the workings of both a driver and a power output element can be confirmed simultaneously or independently with use of the parts that can be obtained easily.
