9.1 Pulse Output :
Pulse output is the potential free, very fast acting relay contact which can be used to drive an
external mechanical counter for energy measurement.
This
pulse output can be congured to any of the following parameter through
instrument’s
setup parameter screen
1) Active Energy (Import) 2) Active Energy (Export)
3)Reactive Energy (Import) 4)Reactive Energy (Export)
5)Apparent Energy
This instrument is provided with either 1 or 2 relay for pulse output as well as for limit switch
9. Relay output (Optional) :
