LU-921M memory type two channels controller has two independent channels,the input of them maybe different.The fast and accurate non-linear algorithm ensures the accuracy of digitized sampling.

 

It can achieve the function of differential algorithm alarm or transform through the parameters setting of alarm source and transform source.
