GL7-HSV, high-speed voltage module


Product Description

GL7-HSV, 4-ch, high speed voltage amp, high isolation per channel, 1M samples/s, 1mV to 100V F.S. and 1-5V F.S.

Dynamic high speed recording module inputs voltage signal from displacement sensors to proximity sensors that fluctuates in high speed.  The signal recorded by a high resolution 16-bit Analog-to-Digital converter samples the measurement data at maximum 1MS/s (1µs) interval.
