This dual-output structure enables on-site display and remote transmission of the acquired electrolytic cell voltage data, which not only solves the problems existing in the prior art and meets the needs of various application scenarios, but also realizes real-time on-site display of voltage data and improves the ease of operation. In addition, this solution adopts a modular and standardized design, which facilitates expansion and maintenance and is suitable for real-time acquisition and monitoring of electrolytic cell voltage.

[0039] The cabinet 101 measures 500*250*550mm. A vertically arranged mounting plate 1011 is installed inside the cabinet 101.
