Abstract

PURPOSE:To perform the life test of the opening defect of the reed relay easily and rapidly, by performing the control of the relay driving number, the measurement of open ampereturn number, and printing-out of these results with the microprocessor as the center. CONSTITUTION:Microprocessor (MPU)8, ROM9, D-A converter 10, and interface (PIA)11 are connected by data bus 12 and address bus 13 to constitute the basic system. The output of D-A converter 10 is applied to coil 15 of the reed relay after amplified by power amplifier 14. Switching of contact 16 of the reed relay is always monitored by PIA11. MPU8 controls the D-A converter by the program of ROM9 and checks the change of the open ampereture number of the reed relay while monitoring turning-on and off of the contact through the PIA and prints out the result through the PIA by printer 18.
