EM4 DIN is an advanced utility meter capable to measure not
only the usual consumed energies but also gas and water by
means of the optional dual contact inputs module.
The main advantages
• High accuracy and resolution for a fine cost calculation.
• Simultaneous indication of both active and reactive energy
allowing the user to read the variables at a glance.
• Displaying of the active power demand with manual or
external synchronisation. The fixed power supply costs are
calculated with the same system used by the electricity
board.
• Management of the pulses from gas and water meters
based on single or dual tariff calculation and energy multi-
tariff management (by means of two selection contact
inputs) giving more flexibility and meeting the application needs.
• Metering of energy, water and gas in the same instrument
allowing the data transmission by means of the same
communication port. Now available also via Dupline.
• Effective control of phase sequence, serial communication
and wrong connection of the current inputs statuts making
the instrument installation: easy, fast and free of wiring errors.
• Self power supply working even in case of one phase
line failure granting continuous metering of energy.
