720212 High-Speed Isolation Module
The Yokogawa 720212 Isolation Module sets a new benchmark by redefining the limits of high-speed, high-accuracy isolated measurement.
Combining 200 MS/s sampling with 14-bit resolution, it brings together speed and safety in ways that few digitizers can. Designed for engineers who need reliable, high-fidelity data in electrically demanding environments, this module represents the next evolution in precision isolation technology.
Key Features
- High-Speed Data Capture with Fine Detail: Sample at 200 MS/s to capture switching events, transients, and noise dynamics with exceptional clarity and 14-bit precision
Optically Isolated Channels: Each input channel is optically isolated, providing robust protection against ground loops and common-mode interference while maintaining accurate differential measurements even in high-voltage systems.
Using high-speed optical fiber-based transmission, IsoPRO™ technology enables 1kV isolated measurements*. The module achieves high-speed ADC clock and data isolation.
Optically Isolated Channels: Each input channel is optically isolated, providing robust protection against ground loops and common-mode interference while maintaining accurate differential measurements even in high-voltage systems.- Exceptional Signal Integrity: The combination of high sampling rate, wide dynamic range, and low noise floor ensures that every captured waveform reflects true system behavior - critical for high-speed power and control analysis
- Seamless System Integration: Fully compatible with Yokogawa’s ScopeCorder (DL950) and High-Speed DAQ (SL2000) platforms, the 720212 extends system capability without adding setup complexity.
- Engineered for Modern Power and Energy Applications: Purpose-built for inverter testing, EV drivetrain development, and renewable-energy conversion systems, the 720212 delivers the precision and safety required to observe high-efficiency inverters operating with high voltages, large currents, and ever-increasing switching speeds
