Voltage measurement transducer MB-1U-1

MAX-MB-1U-1, 5908312595328
With Modbus RTU.
The transmitter MB-1U-1 is designed to measure the voltage and exchange data using the RS-485 port in accordance to MODBUS RTU protocol.

Functioning
The module measures the value of input voltage (AC or DC voltage circuit). Reading the value of the input voltage and setting all parameters of communication are realised  by the user via RS-485, using MODBUS RTU communication protocol.
Switching power supply voltage is indicated by a green LED U. The correct exchange of data between the module and the second device is indicated by a yellow LED Tx.
The transmitter measures the RMS voltage TrueRMS, which ensures high measurement accuracy even with distorted waveforms.

Reset communication settings
Under cover is available code switch.
Details of resetting available in the instructions below.
