Product characteristics:

1，The photoelectric isolation switch is used to isolate the voltage acquisition of each channel completely；

2，The 16-choice 1 analog switch is used to ensure that only one channel is switched on in unit time and not affected by ground difference；

3，Overvoltage protection with maximum withstand voltage of 1000V；

4，Single station supports 32-channel voltage detection at the same time；

5，Adopting 24-bit high-precision ADC imported acquisition chip。
