Pulse output from EM306A 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.
Pulse output from EM306A meter can be used as
alarm generator or total energy controller by
interfacing it with Pre-settable counter and control
circuits (Contractors, 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.
