overview

　LNX-211V-L24 is a voltage monitor that can measure 4-channel analog voltage (±10V) via LAN. The LAN side and each channel are independently insulated. Each channel is equipped with an AD converter, allowing simultaneous measurement of 4 channels.
The power supply can accept a wide range of power input from 8 to 30V DC, and can be supplied from a DC24V power supply that is often used in control panels. It can also be powered from the included AC adapter.
By using the included application LNX-211V Voltage Monitor, it is possible to display measurement results, scaling values, charts, etc. on a remote computer.
By using dedicated control commands, it is also possible to measure analog voltage (±10V) from your own application.

We also have 　a Wi-Fi type, LNX-211V-W24 .

Application Overview

　The application (LNX-211V Voltage Monitor) that comes with the LNX-211V-L24 allows you to use your PC as a high-precision analog voltage (±10V) monitor. Scaling (unit conversion), chart display, logging, etc. are also possible.
Dedicated commands are available, so you can easily measure voltage from Tera Term or your own application.
*Supported OS: Windows 11/10/8.1/8/7 (32/64bit)
