The JUXTA WH4A/V is a non‑isolated voltage transmitter that converts DC current or voltage signals to either current or voltage outputs. It supports dual output configurations (current or voltage) and provides adjustable zero‑point and span settings.
The document lists detailed electrical characteristics such as input resistance, permissible voltage, output ranges, precision, response speed, insulation resistance, and voltage withstand. Mechanical data include dimensions, weight, mounting options, and material construction, while environmental limits cover temperature and humidity ranges.
