LQL3051H HART Board
Product Overview
The LQL3051H is a high cost-performance product, suitable for signal transmission of resistive signals such as magnetic flap level and float ball. This product uses an industrial-grade 24-bit independent Σ-Δ analog front end to ensure high measurement accuracy; comprehensive surge protection and reverse connection protection to avoid misinstallation and misoperation in engineering applications; enhanced software safety design, including low-voltage monitoring reset, multi-task scheduling optimization and other functions. All industrial-grade components are used to ensure long service life and stability. In order to facilitate long-term stocking by large customers, buttons and HART communication devices can be used for configuration settings.
