Application of 89C51 in Small Electromagnetic Relay Parameters Automatic Test Instrument
LU Chun-mei · Journal of Suzhou Vocational University · 2010
The electromagnetic relay is a most important part of the Control System. To keep the system working safely, we need test the parameters of electromagnetic relay often. It designed small electromagnetic relay parameters automatic test instrument based on 89C51 microcontroller, digital potentiometer, A/D converter and so on. And the instrument can test the parameters of small electromagnetic relay automatically and have a good precision.
