The size of the instrument and cutout is shown below (Unit: mm).Then Embed the meter into the 90mm*90mm cutout slot and screw on the fixing buckle, as shown in the picture followed.
The instrument, as shown in the figure below, is in charge of measuring and collecting power data for each loop and is located in the collection layer. Simultaneously, the instrument equipped with a DI/DO and an AO module may achieve switch status monitoring, relay output, and a transmitter, all of which can be adjusted to your specific requirements.
