AC Current Voltage Power Energy Frequency Power Factor Communication Module Meter 100A Ammeter Voltmeter Multimeter with RS485 USB Interface and Split Core Current
Main function The PZEM-014/016 AC communication 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. Function description Voltage :Measuring range:80～260V Current :Measuring range:0～100A Active power :Measuring range:0～23kW Power factor :Measuring range: 0.00～1.00 Frequency :Measuring range: 45Hz～65Hz Active energy :Measuring range: 0～9999.99kWh Communication interface :RS485 interface Read more Read more Other instructions Power supply AC voltage provides two isolated outputs after through the switching power supply, one way is 3.3V provides to the measurement system, the other way is 5V provides to 485 communication circuits and external circuits. 485 communication interface power is(+5 V),current output capability is 100mA Working temperature -20’C ~ +60’C。 Compatible If you have PZEM-022, you can view the data simultaneously with your computer. Comparison of Mutual Inductor Open design is easy to use.Don't need to cut off the wire. Product Size Chart Please check the size before buying Read more
Product 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.
- 5. Note:You can find the software download address in the file:user manual in the listing,if you have any problem about the product,please feel free to contaut us,we will reply you in 24 hours.
