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 (1μs interval).
