Ammeter DC 300V 300A RS485 Interface Voltmeter Current Power Energy Meter Wattmeter Ampermeter PZEM-017 Voltmeter

Features:

1. Voltage over-limit alarm: The voltage threshold can be set, divided into high and low voltage thresholds. When the measured voltage exceeds the set threshold, the alarm state is set.

2. Multi-function parameter detection: Current, power, voltage, energy consumption can be measured, and the measured value can be displayed on the software.

3. Physical layer protocol: Physical layer use UART to RS485 communication interface. Baud rate is 9600, 8 data bits, 2 stop bits, no parity.

4. Application layer protocol: The application layer uses Modbus-RTU protocol to communicate. Currently, it only supports 0x03 (read holding register), 0xO4 (read input register), 0x06 (write single register), 0x41 (calibration), 0x4 (energy clear) and other function codes.

5. High quality: Reinforced material, high temperature resistance, wear resistance, corrosion resistance, environmental protection and pollution-free.
