We provide the software to connect it with the PC. If you want to connect it with other terminal device such as PLC,SCM and so on, please prepare the fitable cable and write the program by yourself.
This document describes the specification of the PZEM-004T AC communication module, 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 TTL interface.
PZEM-004T-10A: Measuring Range 10A (Built-in Shunt)
PZEM-004T-100A: Measuring Range 100A (external transformer)
Very Important Notification:
For this product PZEM-004T, we have the update version to replace the old version. The old version has been sold out and no produce anymore. The update information as following:
1. the new version has the same size and TTL port as before
2. the software is new, we have English software as same as the PZEM-014,016, The communication protocol change to be Modbus–RTU, the display interface is changed. now it can test Voltage ,Current, Power, Power factor, Frequency and Energy 6 parameters.
3. the new version has higher precision, faster refresh speed and the more stability communication than the old version.
4. The new version increase a set for 0-10A
4. This is the module with the very nice outcase.
If there is any question, welcome to contact the service to get more information.
