1) Energy pulse output mode
Meter supports bi-directional active and reactive energy pulse output
function through relay output. Pulse frequency is smaller than 1Hz.
2) Remote control output mode
Receiving command PC or PLC through communication, the relay which
supports electric level manner or pulse manner can be in motion or be
released.
3) Alarm mode
High alarm indicates the relay acts in case of the measuring value more than
the alarm value, while low alarm indicates the relay acts in case of the
measuring value less than that alarm value. Only when all the terms spurring
the relay alarm do not work, the meter has been turned off power or any
software shields the alarm function, does the relay be released.
