1 Overview
ADW310 wireless energy meter is mainly used to measure the active energy of
low-voltage network. It has the advantages of small size, high precision, rich functions,
etc., and has many optional communication methods. It can support RS485
communication, Lora, 4G and other wireless communication methods. The current
sampling mode of the transformer is convenient for users to install and use in different
occasions. It can be flexibly installed in the distribution box to meet the needs of power
metering, operation and maintenance supervision or power monitoring for different areas
and different loads.

4.3 Switch Input/output Terminal
The switch input is the switch signal input method, the instrument is equipped with
+12V working power supply, no external power supply is required. When the external

5
connection is turned on or off, the on or off information is collected through the instrument
switch input module and displayed locally by the instrument. The switch input can not
only collect and display the local switch information, but also realize the remote
transmission function through the RS485 of the instrument, that is, the "remote signal"
function.
Switch output is relay output, which can realize "remote control" and alarm output.
