Voltage Module GL7-V

GL7-MThis is the voltage input module capable to measure voltage for various points of battery pack, electronics circuit, and to measure also voltage of various sensors as displacement, pressure, wind speed, and others. It maintains sampling speed even if the number of modules are increased.
