This paper designs a micro relay test system based on a new floating-point DSP-MS320F28335.This system obtain the data which reflects relay characteristic parameters (coil resistance,pull-in voltage,release voltage and time parameters) through real-time sampling the value of the relay coil current,electric shock voltage,drive supply voltage by internal AD and external sampling electric circuit.These data are displayed on the LCD and transmitted to PC through the serial ports of DSP after being analyzed.The system is small,portable,low in power consumption and high in precise.It can accurately judge the performance of the electromagnetic relay.

Key words: TMS320F28335;time parameter;data acquisition
