Overview

GRANITE Series 8- or 16-Channel 5V Analog Input Module

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

Ideal for Expansion of Analog Measurements
Interfaces directly to a PC for quick setup and data acquisition

Benefits

24-bit ADC and low-noise inputs for increased measurement quality
Distributed data acquisition
Channel count expansion via the CPI bus on Campbell Scientific data loggers
Easier to program than traditional multiplexers
Programmable noise rejection
CANbus 2.0 A/B output available with the Extended Duty (-XD) version
USB 2.0 interface for PC-based operation with Campbell Scientific Surveyor software
