Description
The Graphtec GL7-V is a voltage measurement module designed for use with the GL7000 data acquisition system. It provides 10 isolated input channels with simultaneous sampling, allowing accurate measurement of voltage signals from multiple points at the same time. The module supports a wide measurement range from 100 mV to 100 V full scale, making it suitable for monitoring battery packs, electronic circuits, and various sensors such as displacement, pressure, and wind speed sensors. It uses a 16-bit successive approximation A/D converter to ensure precise and stable signal conversion.
The GL7-V module offers flexible data acquisition with sampling speeds from 1 kS/s to 1 sample per hour and 2 million samples of built-in RAM for each channel. It features strong isolation protection between channels and ground, high common-mode rejection, and low-pass filter options to improve measurement stability. Designed with a screw terminal connection and compact structure, the module maintains consistent sampling performance even when multiple modules are connected, making it suitable for complex multi-channel measurement applications.
