VCL-2786, NTP to 16 x IRIG-B Converter, (NTP Client)
Time Distribution Unit

Get Data Sheet

The VCL-2786, NTP to 16 x IRIG-B Converter (NTP Client), Time Distribution Unit is designed to provide up to 16 IRIG-B outputs and / or 16 IRIG-B and / or 1PPS (Pulse per second) and / or NMEA-0183 (mix and match), that is synchronized from a NTP Server to provide time synchronization to private networks such as Electric Sub-Stations, Railways and Metro (ticketing and platforms) networks, Airports and Air-Traffic Control facilities, Power Distribution and Transmission companies, Oil and Gas Utilities, ISPs and Cable TV networks as well as to Campus networks. The VCL-2786 operates as NTP Receiver / NTP Client with multiple interface option. Our solution simultaneously supports IRIG-B (Mudulated / Unmodulated), NMEA 0183, 1PPS (Pulse per Second), and optical 1PPS port.
