1、 Product Overview
The PK6023 module is an intelligent electrical parameter acquisition module that can measure the true effective values of three-phase current and voltage, as well as parameters such as active power, reactive power, power factor, frequency, and electrical energy. Its output is an RS-485 digital signal, which includes parameters such as three-phase voltage, current, active power, reactive power, power factor, frequency, and electrical energy. Can replace voltage, current, power, power factor, frequency and other transmitters, as well as the input modules for measuring these transmitters. And it comes with 2 switch inputs and 2 switch outputs (1 can be set as the upper and lower limit alarm output for each parameter).
