Current intensity transmitter with MODBUS RTU output MB-1I-1 15A F&F
Product description
The AC-1I module is designed to measure AC or DC current and convert the measured quantity to a unified analog current output signal in the range of 4÷20 mA.
Purpose
AC-1I current transducer is designed to measure AC or DC current intensity and convert the measured quantity to unified analog output current signal in the range 4÷20 mA.
Operation
Current intensity transmitter with MODBUS RTU output. single-phase 15 A AC/20 A DC. direct.
Current intensity transmitter MB-1I-1 is designed for AC or DC current measurement and data exchange via RS-485 port in accordance with MODBUS RTU protocol.
Operation
Current intensity transmitter MB-1I-1 is adapted to work with a current transformer with a secondary current of 5 A.
The module continuously measures the current flowing through the measuring input. Reading the value of the measured current intensity and setting all communication parameters is realized through RS-485 port using MODBUS RTU communication protocol. Activation of the power supply voltage is signaled by the lighting of the green U LED. Correct data exchange between the module and the other device is signaled by the illumination of the yellow LED Tx.
The transmitter measures the rms value of the current TrueRMS, which guarantees high measurement accuracy even with distorted waveforms.
Reset of communication settings
A code switch is available under the facade of the module.
Details on resetting are available in the manual.
The program allows test reading of values and setting of communication and configuration parameters of the transmitter.
Communication of the transmitter with a PC by means of the WE-1800-BT USB converter.
