| Abstract: | In order to help technical personnel select relay, this paper puts forward a method to test the time parameters （including operation time, release time and contact bounce time） of micro electromagnetic relay. This method is based on one CPLD and makes full use of its resource to implement the measurement of multiple time pa- rameters. The hardware structure and circuit principle diagrams of each part are given. Through experiments we de- termine that the range of time parameter tester designed in this paper is 0 - 99.99 ms and the minimum resolution is 1 μs. In addition, this circuit has other advantages such as fast measuring speed, small volume, low cost and easy operation. |
