Microprocessor technology for autonomous clocks and self-setting slave clocks for displaying hours, minutes, and seconds with adjustable hand behavior. 

Modular movement of the latest technology for the display of hours and minutes or hours, minutes, and seconds. For illuminated and non-illuminated clocks up to Ø 80 cm with transparent and non-transparent dials. All types with central nut fixing. Autonomous operation with DCF 77 or MSF 60 radio signal movement (cascading of up to 4 movements possible).

Behavior of the second hand adjustable by means of a DIP switch. 
In slave-clock, operation iscontrolled by

• serial ASCII time telegram RS 232 / RS 422 over standard telegram IF 482,
• audio-frequency time code (IRIG-B, AFNOR or DCF-FSK),
• special serial protocol over RS 485. Used to control and monitor slave clocks and clock illumination.

Self-setting movement for indoor and outdoor slave clocks used in

LAN-based time systems.

It is available in different variants: for clocks with or without illumination, to display hours and minutes or hours, minutes, and seconds.

This high-technology LAN device can be synchronized from a time server or a Net Master Clock via NTP Multicast or Unicast (IP based).

The NBU 190 can be powered via PoE (Power over Ethernet) and/or 24 VDC.In Unicast mode, DHCP can be used to simplify IP configuration during installation.
Additionally, the NBU 190 can be configured by using special software. 
Cascading of up to three slave movements is possible. The slave movements are synchronized, supervised, and supplied by the master movement.
