The Yokogawa 720250 Voltage Module is a high-speed data acquisition module for precision measurement of transient and steady-state voltage signals in industrial and laboratory environments. Operating at 10 MS/s with 12-bit resolution, it delivers accurate waveform capture across a 3 MHz bandwidth. Two optically isolated channels leverage IsoPRO™ technology to enable safe measurements up to 800 V while rejecting ground loops and common-mode interference. DC accuracy of ±0.5% ensures reliable quantification of voltage behavior in demanding test scenarios.
