The Yokogawa 720254 is a 4-channel isolated data acquisition module delivering 1 MS/s sampling and 16-bit resolution for high-precision multi-signal measurement. Optical fiber-based IsoPRO™ isolation technology enables direct measurement up to 200 V or probe-based measurement to 600 V, with ±0.25% DC accuracy. The module eliminates ground loops and common-mode interference through galvanic isolation, making it ideal for simultaneous waveform capture in electrically noisy environments.
