Simulated relay of operation fault

The simulated relay of operation fault is used for testing the reliability of testing systems of relay. This device can output voltage according to on or off of the input coil circuit and generate scheduled contact fault to simulate the contact fault of relay. This device bases on the MCU, and consists the subsystems of inputting module, man-machine conversation module, controlling module and outputting module. With accessorial software, this device simulates the motion under the normal and disabled situation to carry out the functions of simulating the operation fault of relay. The simulated relay of operation fault has good man-machine conversation interface, economy prices and small cubage, which works steadily and can be simply handled. The experiment result indicates that this device can perfectly simulates contact faults of relays to furtherly test and improve the reliability of the testing system of relay reliability.
