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.

Features

Extensions

The base system 6844(RC) is equipped with function boards for the output of required signals according to the provided customer specifications. The possible number of functions boards to be integrated and upgraded is primarily determined by the number of available slots in 19" rack and the power supply capacity.

Please note the following assignment:

  • Board number _ _ _ _ RC: only available for system 6844RC
  • Board number _ _ _ _ (RC): available for system 6844 as well as system 6844RC
  • Board number _ _ _ _ : only available for system 6844
