可编程控制器在高于24V的直流电压等级控制回路中应用时需解决输入模块的电压变换和谐波干扰等问题。
In the application of above 24V fort current voltage grade control circuit, Voltage Alternating and resonant wave interference of input model for Programmable Logic Controllers must be resolved.
系统以DSP为控制核心，可自动识别并适应不同的电压和电流等级，采用程控放大、变化采样频率以获得优化的阵列测试效果。
The tester with DSP core could get excellent results by judging and adopting the different value of voltage and current, programmed amplifying and changing the frequency of sample.
