The Yokogawa 720211 is a 2-channel isolation module delivering 100 MS/s sampling at 12-bit resolution for high-voltage measurement applications. It uses IsoPRO™ technology with optical fiber-based transmission to provide 1 kV isolated measurements when paired with compatible probes, or 200 V DC direct input. The module captures fast-changing signals across a 20 MHz bandwidth while maintaining ±0.5% DC accuracy and approximately 1 MΩ ± 1% input impedance.
