MFM376-230VAC / MFM376-CPulse 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.
PROCESSINTEGRATION
MFM376-230VAC / MFM376-CPulse 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.
