MB-3I-1 5A current transducer
current transducer with MODBUS RTU output.
Three-phase 5 A AC.
For use with current transformers.
The MB-3I-1 current transducer is designed to measure alternating or direct current and to exchange data via an RS-485 port in accordance with the MODBUS RTU protocol.
Operation of the MB-3I-1 three-phase current transducer
TheMB-3I-1 current transduceris designed to work with current transformers with a secondary current of 5 A.
The module continuously measures the current flowing through the measurement inputs. The measured current value is read out and all communication parameters are configured via the RS-485 port, using the MODBUS RTU communication protocol.
The application of supply voltage is indicated by the green ‘U’ LED lighting up. Successful data exchange between the module and another device is indicated by the yellow ‘Tx’ LED lighting up.
The transducer measures the TrueRMS value of the current, which guarantees high measurement accuracy even with distorted waveforms.
Resetting communication settings
A DIP switch is located beneath the module’s front panel.
Details on resetting are available in the manual.
MB Config
The programme allows you to test-read values and configure the transmitter’s communication and configuration parameters.
The module communicates with a PC via theCN-USB-485 USB converter.
The programme is free of charge.
