Overview
1.We provide the software to connect it with the PC. If you want to connect it with other terminal device such as PLC, and so on, please prepare the fitable cable and write the program by yourself.
2. 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)
