MB-3I-1 15A three-phase current transducer, Modbus RTU
Why choose the MB-3I-1 15A?
The MB-3I-1 15A enables current measurement across three channels and data exchange via RS-485 Modbus RTU. This version of the transducer is designed for direct measurement of 15 A AC / 20 A DC.
What does this mean in practice?
- The device has 3 independent current measurement channels.
- The range of each input is 0–15 A AC / 0–20 A DC.
- Direct measurement is possible within the input range.
- It is compatible with current transformers with a secondary current of 15 A.
- True RMS measurement is performed for AC current.
- Data from all channels is accessible via RS-485 Modbus RTU.
Reset communication settings
A DIP switch is located on the underside of the module.
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.
