N4VIA02 Multifunctional RS485 Ammeter Voltmeter – 0-30V / 0-5A Modbus RTU DC Power Measurement Module for PLC SCADA Industrial Automation

Description:

Power supply voltage: DC 8-25V(12V recommended);



Operating current: 8-13MA;



MODBUS RTU protocol: 03 read command, 06/16 write command.



Serial port Baud rate: 1200 2400 9600(default) 19200 38400 57600 115200 ,N/E/O,8,1;



By modifying the RS485 address, up to 247 modules can be cascaded (more than 16 please use R485 repeater);



Voltage and current values can be read;



Current measurement range: 0~1A, 0~2A, and 0~5A. It is recommended to select a version with a smaller range within the range that meets the measurement;



Voltage measurement range: 0~30V;



Measurement accuracy: 1%. If the read value is too different from the actual value, recalibrate



Size: 72X 47 X 12MM(only board),87X 50X 37MM(with case)



Weight: 23g(board only),68g(with case)



Note:

This product is used to collect small current signals from time to time. If you need a 4-20MA signal collector, please choose the following products: N4AIA04 N46IB02 N43IC04




Note: The module will restore factory settings and restart automatically after 5 seconds of shorting the RES port.
