Overview
The GRANITE™ VOLT 116 easily expands the channel count on your data-acquisition system. It has 16 differential or 32 single-ended input channels, as well as four excitation channels. It provides programmable, precision excitation for standard sensor measurements and power outputs for controlling sensors and peripherals. The VOLT 116 features a 24-bit, analog-to-digital converter with low-noise performance for superior analog measurements.
Benefits and Features
- 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
