LQL2485M RS485 Board
Product Overview
The LQL2485M level transmitter features a four-digit digital tube display and is suitable for transmitting resistance signals (such as reed switches). The LQL2485M adopts comprehensive electrical isolation to reduce damage and interference caused by high-current signals on the RS485 bus to the device. This product uses a 24-bit Σ-Δ analog front end to ensure high measurement accuracy; comprehensive surge, lightning, and reverse polarity protection to prevent incorrect installation and operation in engineering applications; enhanced software safety design including low-voltage monitoring reset, multi-task scheduling optimization, and other functions. The LQL2485M is fully built with industrial-grade components to ensure long service life and stability.
