MB-1I-1 5A single-phase current transducer, Modbus RTU
Why choose the MB-1I-1 5A?
The MB-1I-1 5A is a current transducer designed to work with a current transformer with a secondary current of 5 A. The measurement result is available digitally via RS-485 Modbus RTU.
What does this mean in practice?
- The 0–5 A AC measurement input is designed for the secondary signal of a 5 A current transformer.
- AC current measurement is carried out using the True RMS method.
- The measurement result is available in the Modbus RTU registers.
- The sampling frequency is 10 Hz.
- Communication interface: RS-485.
- The module also allows configuration of communication parameters.
Important: the current transformer must be selected separately.
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 set the transducer’s communication and configuration parameters.
Communication between the module and a PC via theCN-USB-485 USB converter
The programme is free of charge.
