Switching output is relay output, can achieve the remote-control and alarm output.
The switch input adapts the method of on-off signal input and powered by outer power supply.
It can be gotten by meter when there is a change of on or off via a switching input module. The
parameter of switching input can not only get and show the state of local switching information
but also achieve the communication via RS485, which called “remote information” function.
Note: (17-18) are active energy pulse, (60,61,62,69) are NTC temperature measurement port,
(15,16) are clock pulse, (19,20) are reactive energy pulse, (40,41) are switch output and multiplex
with (60,61), (24,25) are 2 path of communication, (30，39) are switch input and multiplex with
(62,69).
7 Function description
7.1 Measurement
The meter can measure all electrical parameters such as voltage, current, active power,
reactive power, apparent power, power factor, frequency, 31
st
harmonic and total harmonic. The
value format of voltage, current, frequency and power are listed as below.
Example: U = 220.1V，f = 49.98Hz, I = 1.99A，P = 0.439kW
