Multifunctional measuring transducer ENIP-2

The high quality of ENIP-2 measurements is achieved through the use of original signal processing algorithms, which allow performing synchronous measurements of the parameters of the electrical network mode. ENIP-2 has various interfaces and supports standard exchange protocols: Modbus RTU / TCP, IEC 60870-5-101 / 104, as well as the “digital substation” protocol IEC 61850, the implementation quality of which is confirmed by the international certificate DNV GL (KEMA Laboratories). ENIP-2 is produced in three versions: —— in a plastic casing for mounting on a DIN rail (Standard); —— in a metal casing (Compact); —— in a casing with a color liquid crystal touch display (USVI). Executions differ from each other. functional purpose, sets of interfaces and exchange protocols, composition of discrete inputs and outputs. ENIP-2 is easily mounted in the relay compartments of switchgear, on panels or cabinets of the control room. Due to its wide temperature range, the device can be used in unattended unheated facilities.
