High-speed Voltage Module GL7-HSV

GL7-HSV This is the high-speed sampling voltage input module capable to measure high-speed voltage as control signal in inverter-based system, output of sensors in the characteristic test, output of vibration/displacement meter, and others. It can capture the signal by a high resolution using 16-bit converter even if it is sampled at fast speed as maximum 1MS/s (1ƒĘs interval).
