Communication module for PEACEFAIR PZEM-017 DC energy and voltage consumption meter (No. 8)

Main features: 1. It is mainly used to measure DC voltage, current, active power, frequency, and power consumption. 2. The current measurement range is 50A, 100A, 200A, and 300A, depending on the external shunt specifications. 3. You have a choice of 10 different kits, sufficient to meet your various needs. 4. The physical layer uses the UART to RS485 communication interface, with a baud rate of 9600, 8 data bits, 2 stop bits, and no parity. 5. The application layer uses the ModbusRTU protocol for communication and only supports function codes such as 0x03, 0x04, 0x06, 0x41, 0x42, etc. Specification: This module is primarily used to measure DC voltage, current, active power, frequency, and power consumption. The module has no display function; data is read via the RS485 interface. Features: It is primarily used to measure DC voltage, current, active power, frequency, and power consumption.

When the measured voltage exceeds the threshold, it can trigger an alarm. (If <7V, please use the independent power supply mode) 200A, 300A four types of shunt) Resolution: 0.01A Measurement accuracy: 1% Power: Measurement range: 0.2-90kW Resolution: 0.1W Measurement accuracy: 1% Energy consumption: Measurement range: 0-9999kWh Resolution: 1Wh Measurement accuracy: 1% Energy recovery: use the software to reset Overvoltage alarm: Default high voltage threshold: 300V Default low voltage threshold: 7V Communication interface: RS485 interface Operating temperature: -20 ~ 60 ℃ Product size: approx.9 * 6 * 2.3 cm / 3.5 * 2.4 * 0.9 inches Weight: approximately 77 g ~ 287 g / 2.7 oz ~ 10.1 oz Register Address Description Resolution 0x0000 Voltage value 1 LSB corresponds to 0.01 V 0x0001 Current value 1 LSB corresponds to 0.01 A 0x0002 Low power value 16 bits 1 LSB corresponds to 0.1 W 0x0003 High power value 16 bits 0x0004 Low energy value 16 bits 1 LSB corresponds to 1 Wh 0x0005 High energy value 16 bits 0x0006 High voltage alarm state 0xFFFF is an alarm, 0x0000 is not an alarm 0x0007 Low voltage alarm state 0xFFFF is an alarm, 0x0000 is not an alarm. Register Address Description Resolution 0x0000 High Voltage Alarm Threshold (5~350 V), default value is 300 V. 1 LSB corresponds to 0.01 V. 0x0001 Low Voltage Alarm Threshold (1~350 V), default value is 7 V. 1 LSB corresponds to 0.01 V. 0x0002 Modbus-RTU Address Range is 0x0001~0x00F7. 0x0003 Current Range 0x0000: 100 A, 0x0001: 50 A, 0x0002: 200 A, 0x0003: 300 A.

When the input test voltage is less than 7V, it must provide an independent 5V operating voltage via the USB port. DO NOT use the PC's USB port as an independent power supply, as this may damage the PC.
