Sub-Master (Slave) Time Server System 6844(RC)-SUB with NTP LAN Board(s) 7273(RC) / 7274(RC)

Short Description

By implementation of up to two (2) NTP LAN Boards 7273(RC) or NTP LAN Boards 7274(RC) (10/100/1000 Mbit/s autosensing, VLAN, Bonding, PRP) system 6844(RC)-SUB becomes a highly accurate NTP Stratum 1 Time Server for synchronization of computers and industrial networks.

System 6844(RC)-SUB can either be delivered with one or two implemented NTP LAN Boards 7273(RC) / one or two NTP LAN Boards 7274(RC) from the factory or subsequently extended by board(s) 7273(RC) / 7274(RC) in the field. The modular design structure of system 6844(RC)-SUB also allows the combination of one board 7273(RC) / one board 7274(RC) with any other function board suitable for system 6844(RC)-SUB.
