Overview
The Granite™ Volt 108 easily expands the channel count on your data acquisition system. It has eight differential or 16 single-ended input channels, as well as two excitation channels. The Volt 108 provides programmable, precision excitation for standard sensor measurements and power outputs for controlling sensors and peripherals. This module features a 24-bit, analog-to-digital converter with low-noise performance for superior analog measurements.
Key Advantages
Interfaces directly to a PC for quick setup and data acquisition
