The Yokogawa 701262 is a two-channel isolated input module that simultaneously acquires voltage and temperature signals with integrated anti-aliasing filtering. It captures universal voltage inputs up to 42 V peak and thermocouple measurements across 12 industrial types, from −200 to 2300 °C, on a common time base. This enables synchronized evaluation of electrical and thermal behavior in power electronics, battery testing, and design validation workflows.
