Pulse output from meter can be interfaced into a
process through a PLC for on line control of energy
content in the process.
If the PLC has a self excited digital input, external DC
supply is not needed.
The kWh pulse is also used to derive average kWh
information at the PLC.
PROCESS INTEGRATION
Pulse output from meter can be used as alarm generator
or total energy controller by interfacing it with Pre
settable counter and control circuits (Contactors, Relay,
Trip Circuit).
The counter is loaded with the maximum energy
consumption. When count reaches setpoint it provides
output to control circuit to take appropriate action.
