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

In the minimal configuration of ENIP-2 Standard provides the main function – measuring the parameters of the three-phase electrical network. The device has one or two RS‑485 ports and it does not have built-in inputs and outputs for processing digital and analog signals. If in the future it is necessary to supplement ENIP-2 with such signals, you can use the ENMV-1 input/output modules (up to 10 pcs.) by connecting them to the second RS-485 port. The second port also serves as an interface for data exchange with ENMI display module.
