Remote control: By receiving a command from a PC or PLC, the relay operates. The relay’s
operating status will be kept until a special timer overflows or the meter is de-energized. If,

The relay’s operating status will be kept within the period of time for timing. When the
timer overflows, the relay will be released and kept released.
5.3 Pulse outputs
PMAC735E provides two pulse output outlets, one for active energy pulse output and the other
for reactive energy pulse output. The user can self-define the type of energy, and the default types
are active energy input and reactive energy input. The user can also forbid pulse outputs.
A typical wiring mode of external acquisition equipment is shown as follows:
