11.921.140, PEWETA main watch type series 921, metal housing for installation in 19 component carriers.

Total output power 1 A at 24 V line voltage. Impulse mode freely programmable as minute impulses, second impulses or DCFport24 telegram. Controls up to 160 conventional minute pulse or 50 PEWETA DCFport24 telegram support units at 24 V line voltage. Parallel operation of conventional minute pulse and PEWETA DCFport24 telegram side-watches on the same side-watch line is possible. An integrated power supply battery (rated power 1500 mA / h) ensures a time-limited operation of all connected side-watches in the event of power failure, all connected side-watches are automatically set to the current time. Voltage and current monitoring of the side-watch lines with alarm detection in the event of interference by red alarm LED and by display on the display as well as messages via SYSLOG (network). Freely configurable and 16 preprogrammed time zones for world-time clock systems. For the purpose of this Regulation, the following definitions shall apply: A temperature-compensated quartz oscillator (TCXO) ensures a flow deviation of less than 0.1 seconds / 24 hours in open-air. The most simple commissioning by means of clear text operator guide in the LCDdisplay or web browser. Ethernet 10 / 100 Mbit / RJ45: HTTP, NTP, (S) NTP, DHCP, SYSLOG, SNMP. Main watch as NTP server, Stratum 1 (option), for synchronization of NTP system watches, servers, PCs, printers, switches, etc. USB interface for software updates. Metal housing as a push-in cassette for installation in 19 component carriers, B 213 (42 TE) x H 128 (3 U) x T 230 mm (component carrier is accessories). Operating voltage 110-240 VAC / 50-60 Hz., 4 side-clock lines, no switching contacts, with power reserve, including network connection (RJ45) for menu settings via LAN. Optional as a NTP client and as a NTP server.
