METER AMPEROMETER PEACEFAIR PZEM-004T AC 100A Description: It is an electrical monitoring test module that can be used to test power, energy, voltage and current, and then displayed on a computer or other terminals. It can store data when power off, and store stored energy data before power off. Designed with one reset button, you can reset the energy data by simply pressing one button. The TTL serial port can communicate, read and set parameters with different terminals via USB adapter. Features: It is an electrical monitoring test module that can be used to test power, energy, voltage and current. The connection of this module is divided into 2 parts: voltage, input current and serial port communication, and you can use different TTL adapters to make it communicate with different terminals. The test module is designed for high power testing of equipment and you can observe the accumulation process intuitively for low power (within 100W) load test. There is a button on the energy reset module, just press and hold the button for 5 seconds and release, then press the button again to complete the energy reset. Displays via PC or other terminals, and you can download software for PC. For other terminals, it must be programmed by itself.

If you need to communicate with a device that ma USB or RS232 ( np computer), TTL adapter is required. The following table shows the communication protocols of this module: Function Head Data1- Data5 Sum Tension B0 C0 A8 01 01 00 (Computer sends a command to read voltage values) 1A A0 00 E6 02 00 00 (The meter corresponds to a voltage value of 230.2V) 88 Current B1 C0 A8 01 01 00 (Computer sends command to read current values) 1B A1 00 11 20 00 00 (The gauge corresponds to a current value of 17.32A) D2 Average power B2 C0 A8 01 01 00 (Computer sends command to read average power value) 1C A2 08 98 00 00 00 (The meter corresponds to the active power value being 2200w) 42 Reading energy B3 C0 A8 01 01 00 (Computer sends energy reading command) 1D A3 01 86 9f 00 00 (Counter corresponds to energy value is 99999wh) C9 Set the module address B4 C0 A8 01 01 00 (Computer sends address setting command, address is 192.168.1.1) 1E A4 00 00 00 00 (Measurement responds that address has been successfully set) A4 Set the power alarm threshold B5 C0 A8 01 01 14 (computer sends command to set power alarm threshold) 33 A5 00 00 00 00 (The meter responds that the power alarm threshold has been set successfully) A5 Illustration of the communication protocol: 1. Set communication address: 192.168.1.1 Reply Date: A4 00 00 00 00 00 A4 In sending commands: B4 C0 A8 01 01 00 = 21E (hexadecimal), the cumulative sum data is 21E, take the last two bytes of 1E as the data of the cumulative sum in the sending commands; in the response data: A4 00 00 00 00 = A4 (hexadecimal), the cumulative sum data is A4, i.e. the data of the cumulative sum in the response. 2. Set power alarm threshold: 20 KW Response data: A5 00 00 00 00 00 A5 The power alarm value of this module is based on KW units, and the minimum alarm value is 1KW, the maximum value is 22KW. 3. Read the voltage Response data: A0 00 E6 02 00 00 88 4. Read the current
