GL7-V Voltage Module
Universal isolated input module for low voltage between 0 to 100V. At 1ms (1 kS/s) sampling speed, you are able to monitor up to 100 channels with 10 modules per GL7000 main unit. Synchronizing up to 5 units, GL7000 can monitor up to 500 channels max at 1ms sampling interval using multiple GL7-V modules.* Module is best suited for multi-channel measurements for battery stack, electronics circuit, and to measure multiple displacement, pressure, wind speed, and other scaled linear voltage input from sensors measuring physical measurements.
*Requires B-559 sync cable.
