overview

　The LNX-210A-L24 is a current monitor that can measure 4-20mA signals on 4 channels via LAN. The LAN side and each channel are independently isolated. Each channel is equipped with an AD converter, allowing simultaneous measurement of 4 channels. The power
supply can accept a wide range of inputs from 8 to 30V DC, and can be supplied from a 24V DC 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-210A C-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 4-20mA from your own application.

We also have 　a Wi-Fi type, LNX-210A-W24 .

Application Overview

　The application (LNX-210A C-Monitor) that comes with the LNX-210A-L24 allows you to use it as a high-precision 4-20mA signal monitor on your PC. It also allows scaling (unit conversion), chart display, logging, etc.
Dedicated commands are available, so you can easily measure current from Tera Term or your own application.
*Supported OS: Windows 11/10/8.1/8/7 (32/64bit)
