●Accurately measure voltage, current (true effective value), active power, reactive power, power factor, frequency, apparent power, fundamental active power, harmonic active
power,fundamental reactive power, Forward and reverse active energy, forward and reverse reactive energy and other electrical parameters.
●With 2 channels of digital input, 2 channels of digital output(can be set as alarm output), 2 channels of active energy pulse output and 1 channel of 4-20mA analog output; the update period of the real-time data of the module can be set from 40mS to 1000mS; the data lt can be uploaded automatically; it can truly realize the "four remote" function.
●Support Modbus-RTU protocol.
