AC Current Voltage Power Energy Frequency Power Features
-
1. Multimeter: the module is mainly used for measuring AC voltage, current, active power, frequency, power factor and active energy, the module is without display function, the data is read through the RS485 interface and computer software.
-
2. Over power alarm: active power threshold can be set, when the measured active power exceeds the threshold, it can alarm.
-
3. Physical layer protocol: physical layer use UART to RS485 communication interface Baud rate is 9600, 8 data bits, 1 stop bit, no parity.
-
4. Application layer protocol: the application layer use the Modbus-RTU protocol to communicate. At present, it only supports function codes such as 0x03 (Read Holding Register), 0x04 (Read Input Register), 0x06 (Write Single Register), 0x41 (Calibration), 0x42 (Reset energy). etc.
