PZEM-017 DC Voltage Current Power Meter 300A RS485 Module

PZEM-017 DC Voltage Current Power Meter 300A RS485 Module Description

PEACEFAIR PZEM-017 DC Voltage Current Power Energy Consumption Meter Communication Module (#2)
This module is mainly used for measuring DC voltage, current, active power, frequency and energy consumption, the module is without display function, the data is read through the RS485 interface.


Features:



It is mainly used for measuring DC voltage, current, active power, frequency and energy consumption.


The current measure range is 50A, 100A, 200A, 300A depend on the external shunt specification.


There are 10 different kits to choose, enough to meet your various need.


Physical layer use UART to RS485 communication interface, baud rate is 9600, 8 data bits, 2 stop bit, no parity.


The application layer use the ModbusRTU protocol to communicate, it only supports function codes such as 0x03, 0x04,0x06, 0x41, 0x42, etc.


Voltage threshold can be set, divide into high voltage and low voltage threshold, when the measured voltage exceeds the threshold, it can alarm.

Note:



RS485 interface is passive output, need external connect 5V power supply and the external power supply should 100mA.


When the input test voltage is less than 7V, it must supply 5V independent work voltage through USB port.


Do NOT use the USB port bring by your PC to be the independent power supply, otherwise it may damage your PC.
