LQT202 module
Product Overview
The LQT202 temperature transmitter module is a high-cost-performance product launched by our company, suitable for signal transmission of up to ten types of thermocouples and thermal resistors. This product uses a 24-bit Σ-Δ analog front end to ensure high measurement accuracy; comprehensive surge and reverse polarity protection design avoids misinstallation and misoperation in engineering applications; enhanced software safety design includes functions such as low-voltage monitoring reset and multi-task scheduling optimization. The LQT202 uses industrial-grade components throughout to ensure long service life and stability. To facilitate long-term stockpiling by major customers, configuration settings can be made using a USB communication cable, and no external power supply is required during setup.
