The Yokogawa 720268 High Voltage Module is a 2-channel isolation module engineered for high-amplitude signal acquisition and analysis. Operating at 1 MS/s sampling rate with 16-bit resolution and 300 kHz bandwidth, it captures transient events and waveforms across both DC and AC signals up to 1000 V (DC + AC peak). The module delivers ±0.25% DC accuracy with complete channel-to-channel and channel-to-ground isolation for safe multi-point measurements in electrically demanding environments.
