Time correction unit ENKS-2

Time correction blocks (BKV) ENKS-2 are intended for organizing SOEB (system for ensuring uniform time). ENKS-2, using signals from navigation satellite systems of precise time (GLONASS, GPS), provides determination of coordinates and exact time and counts the time on the built-in clock. ENKS-2 receives signals from satellite navigation systems using an antenna located outside the building. A special bracket is used to mount the antenna. For time synchronization on servers, workstations and other devices, ENKS-2 provides standard exchange protocols NMEA 0183, SNTP. In telemechanics systems, time synchronization from ENKS-2 is provided using commands of the IEC 60870-5-101 protocol. SMPR ENKS-2 provides accurate time synchronization of the built-in clock of the ENIP-2 measuring digital converters with support for synchronized vector measurements. OLED display, front panel control buttons, and a set of interfaces (RS ‑ 232, RS ‑ 485, Ethernet) that provide a variety of options for using the device. In addition, ENKS-2 provides the formation of a verification signal "1 Hz" (PPS). ENKS-2 is a time measuring instrument, entered in the State Register of Measuring Instruments. … ENKS-2 uses standard exchange protocols NMEA 0183, SNTP for synchronization of servers, workstations and other devices. For time synchronization in telemechanics systems, ENKS-2 supports the command C_CS_NA_1 (103) of the IEC 60870-5-101 exchange protocol. When using ENKS-2 in SMPR together with USVI ENIP-2 (PMU), time synchronization is carried out using the IRIG protocol. In addition, ENKS-2 generates a verification signal "1 Hz" (PPS). ENKS-2 is supplied with initial verification of Tech. specifications Time counting accuracy Allowable absolute error of PPS edge synchronization (1 Hz) and IRIG timing mark to UTC scale – ± 500 ns, minimum time correction quantum – 11 ns, allowable absolute error of time scale reproduction in the absence of communication – ± 0.4 s / day Synchronization frequency according to IEC 60870‑5‑101 C_CS_NA_1 (103) from 1 min to 45 days, IRIG – 100 ms, SNTP – upon client request (up to 10,000 NTP requests per second) Interfaces RS ‑ 232‑1, RS ‑ 485‑1: NMEA 0183, IEC 60870-5-101; RS-232-2: NMEA 0183; RS ‑ 485‑2: IRIG ‑ A, IRIG ‑ B, PPS; Ethernet 100Base-T: SNTP Operating conditions and design -40 to +70 ° С, 83 × 100 × 110 mm (plastic, IP40), DIN-rail mounting
