PZEM-004T-100A-D-P
Features:
1. Calibration function, electric energy zeroing function, read and modify slave machine parameters function.
2. The new upgraded pin pulse version is more suitable for PCB integration, convenient for power measurement and calibration error.
3. Physical layer protocol: The physical layer uses the UART to TTL communication interface. The baud rate is 9600,8 data bits, 1 stop bit, and no parity check.
4. CRC check: CRC check adopts 16bits format and occupies two bytes. The generated polynomial is X16+X15+X2+1. The polynomial value used for calculation is 0xA001.
5. Application layer protocol: The application layer uses Modbus-RTU protocol for communication. Currently, only function codes such as 0x03(read hold register), 0x04 (read input register), 0x06 (write a single register), 0x41(calibration), and 0x42 (power zero clearing) are supported. The 0x41 function code is only used internally (the address can only be 0xF8). It is used for factory calibration and returned to factory maintenance. A 16-bit password is added after the function code. The address range of the slave machine is 0x01 to 0xF7. Address 0x00 is used as a broadcast address and the slave machine does not need to reply to the host. Address OxF8 is used as a general address.
Specifications:
Model: PZEM-004T-100A-D-P
Measuring range: 100A
Voltage: 80~260V
Current: 0~100A
Active power: 0~2.3KW
Power factor: 0.00~1.00
Frequency: 45Hz to 65Hz
Pulse output: 1600imp/kwh
Communication interface: TTL interface
Active power (power zero clearing software) : 0~9999.99kWh
Power over-limit alarm: the active power threshold can be set. When the measured active power exceeds the set threshold, the alarm state is set
Power supply: The single-phase power supply in the power grid supplies power to the main circuit through resistance and capacitance step-down. The TTL output communication interface is isolated from the main circuit optically and is a passive output. 5V power supply is required for communication
Operating temperature: -20¡É~+60¡É
Special note:
The TTL interface of this module is a passive interface and needs 5V external power supply, that is, all four ports (5V, RX, TX, and GND) must be connected during communication; otherwise, communication fails. Operating temperature :-20¡É~+60¡É
Compared with the old model, the needle arrangement and new pulse function are welded.
