How to order

provided with digital outputs

that can be either for pulse pro-

portional to the active (imported

and exported) and reactive

energy being measured or for

alarm outputs. In alternative the

RS485 communication port and

3 digital inputs or Dupline port

and 3 digital inputs are avail-

able as an option.

Certified according to MID Directive, Annex

"B" + Annex "D" for legal metrology relevant to

active electrical energy meters (see Annex MI-

003 of MID). Can be used for fiscal (legal)

metrology. Only the total positive energy meter is certified

according to MID.
