Description
- Can be used to measure voltages up to ±40V
- You can select the voltage range (±5V, ±15V or ±40V) in software
- Automatic mode adjusts the range based on present voltage measurements
- Isolated for stability
When a 0-5V voltage input isn't enough, the Phidget VINT ±40V Voltage Input Module can be used to measure voltages up to ±40V. You can select the voltage range (±5V, ±15V or ±40V) in software; a smaller range results in higher precision. This Phidget also has an automatic mode that continuously adjusts the range based on present voltage measurements, so you'll always have the most accurate measurement possible.
This Phidget is electrically isolated, so a power surge on the circuit you're measuring will not damage your VINT Hub or your computer. Isolation also improves stability by eliminiating potential ground loops.
