Network Master Clock - DTS 4801.masterclock


The Network Master Clock DTS 4801.masterclock is developed especially for network environments. It is able to control conventional impulse clocks, self-setting MOBALine or IRIG-B / AFNOR slave clocks and is used as an accurate NTP time reference (time server) for computer systems.

The DTS 4801.masterclock can be synchronized by a time signal receiver (DCF 4500 or GNSS 4500) and/or by NTP time servers (LAN / Internet). The DCF current loop output can be used to synchronize other devices (e.g. master clocks).

The DTS 4801.masterclock is equipped with 4 alarm control inputs either to monitor other connected devices or to link external signals (e.g. from sensors) to switching commands. A serial RS 232 / RS 485 interface with configurable script file, to output special synchronization telegrams, completes the features of this multipurpose master clock.

Alarms are signalled by a relay, with SNMP traps or by e-mail. By means of the management software MOBA-NMS, all DTS devices can be fully operated and monitored.

1 LAN port (RJ45):

  • provides NTP on 4 ports (>250 requests/s)

Multi-purpose device due to the different time code and frequency outputs:

  • 1x DCF/pulse/frequency current loop output
  • 1x MOBALine / DCF active / Polarized Impulses
  • 1x serial output

High precision time:

  • Time reception from GPS, GLONASS, Galileo or Beidou
