ENIP-2 Standard

The ENIP-2 standard has a plastic housing and could be mounted on DIN-rail. If necessary, access to terminals can be restricted with a sealing cover. 

Modifications ENIP-2 Standard differ from each other in the composition of interfaces and sets of inputs and outputs for discrete input-output and analog output.

Only measuring inputs: 

Minimum — 1(2) × RS-485 

With additional input-output: 

Minimum plus — 2 × RS-485 

Optimal — 3 × RS-485, 1 × Ethernet 

Maximum — 2 × RS-485, 2 × Ethernet

One or two RS-485 ports. The second RS-485 port can be used for a redundant data transmission channel, or for connecting external devices. The RS-485-2 port is pinned out to two RJ45 sockets: the left one is used for connecting ENMV-1, and the other one for ENMI.


  • voltages RMS (phase, phase-to-phase and average);
  • currents RMS (phase  and average);
  • power (active, reactive and apparent: per phase and total);
  • frequency;
  • power factor (per phase and apparent);
  • active and reactive energy in direct and reverse directions.
ENIP-2 uses 50 ms sliding window measurement calculation method. The values are updated every 20 ms.

Power quality
  • voltage sequences;
  • voltage unbalance and distortion;
  • curent sequences;
  • current unbalance and distortion;
  • THD;
For monitoring purposes ENIP-2 has a set of confiurable thresholds.


Switchgear equipment control using integrated binary outputs or using external ENMV-1 telecontrol modules, which are connected to ENIP-2.

Data display

Using external ENMI display modules it is possible to visualize values of main measured and calculated parameters. It is possible to display data from single ENIP-2 on several ENMI modules or visualize data from several ENIP-2 on single ENMI module. Display modules may be structurally combined with ENIP-2.
