Typical applications

The following table presents some of the functions of the different meters, the advantages and main applications.

Functions	Advantages	Applications	Meter
Total and partial energy counters	Energy usage monitoring	Sub-billing management Metering applications	iEM3400 / iEM3500 series
Internal clock	Saves the date and time of last reset	Provides the timestamp of the last reset of the partial energy accumulation	iEM3400 / iEM3500 series
Manages up to four tariffs, controlled by the digital input(s), internal clock or communications (depending on meter model)	Categorize energy consumption into On Peak and Off Peak, working days and weekends, or by different electricity sources (for example, from the utility and an electrical generator)	Energy demand management Sub-billing management Identification of local energy consumption behavior by zone, by usage or by feeder	iEM3400 / iEM3500 series
Measures essential electrical parameters like current, average voltage and total power	Instantaneous measurements help you monitor the imbalance between phases Total power allows you to monitor the feeder load level	Monitoring of feeders or any sub-cabinet	iEM3400 / iEM3500 series
Modbus communications	Communicate advanced parameters using Modbus protocol	Modbus network integration	iEM3455 / iEM3555
BACnet communications	Communicate advanced parameters using BACnet MS/TP protocol	BACnet network integration	iEM3465 / iEM3565
Four quadrant calculation	Identification of imported and exported active and reactive energy allows you to monitor energy flow in both directions: delivered from the utility and produced on-site	Ideal for facilities with back-up generators or green power capabilities (for example, solar panels or wind turbines)	iEM3400 / iEM3500 series
Measurement of active and reactive energy	Allows you to monitor energy consumption and production	Manage energy consumption and make informed investment to reduce your energy bill or penalties (for example, installing capacitor banks)
Programmable digital input	Can be programmed to: Count pulses from other meters (gas, water, etc.) Monitor an external status Reset the partial energy accumulation and start a new period of accumulation	This allows for monitoring of: WAGES Intrusion (for example, doors opening) or equipment status Energy usage
Programmable digital output	Can be programmed to: Be an active energy (kWh) pulse output, with a configurable pulse weight Alarm on a power overload at a configurable pickup setpoint	This allows you to: Collect pulses from the meter with a Smartlink system, PLC or any basic acquisition system Monitor power levels at a detailed level and to help detect an overload before the circuit breaker trips
