Communication type lightning arrester online monitorReal time transmission of insulation state assessment fault threshold warning data to LiOu measurement and control

（LE-MOA-601LZ）

Product Introduction

The LE-MOA-601LZ communication type lightning arrester online monitor adopts a precision cast aluminum shell, which increases the mechanical strength and sealing performance of the monitor shell, and the installation size is the same as the original monitor. The functions of the original ordinary monitor are retained, and a microcontroller based A/D conversion and optoelectronic isolation RS485 communication board are installed inside the monitor. The communication terminal is led out from below the monitor, and the communication method and protocol are also the same.
