Plug-in card with 2x RS232/422/485 outputs.

4 plug-in cards at style with rack mounting case): GPS-ANT-BT: GPS synchronisation antenna.BT-DCF-ANT: DCF-77 radio synchronisation antenna.Power supply: 12…24 V AC/DC via master clock.Transmission range: Indoors 100…200 m depending on ambient conditions (for major ranges up to 3 signal amplifiers BTWL-HUV per direction can be used).Transmitter power: 25, 125 and 500 mW adjustable (via master clock).Case: ABS plastic for wall mounting with 2 screws.Accuracy quartz: TCXO, ☐.1 s/ 24 h at 20…25 ☌ (without DCF/GPS).Input (RJ45) for use of master clock as net client to be synchronised via TCP/IP network time source.Alarm messages in case of NTP faults via relay or e-mail possible.the DCF/GPS synchronised BT-M103-WL-NTP master clock acts as NTP server in TCP/IP network and synchronises all other network clients) As enlargement, analogue and digital NTP slave clocks can be synchronised via PC network (i.e.NTP is also used for synchronisation of PC servers and PC workstations in smaller networks (LAN).NTP (Network Time Protocol) protocol for synchronisation of computers in a computer network = international standard for PC time transmission in Internet.NTP Time Server Function in TCP/IP network (RJ45 connection).Software allows hard copy of programming adjustments and alarm messages.All functions and programming are available through download, also continuative functions, which cannot opened from master clock menu directly.Compatible to Windows XP and Windows Vista.Including easy and user-friendly PC software:.Programming of relays in different modes possible: weekly, holidays, vacation period, other special days, astronomic or periodic.3 free programmable potential free switching outputs 1 A / 240 V (to be hard-wired) for control of breaks signalling devices, heating, air conditioning, building illumination, and so on.View of programs, adjustments and signal times.school autonomic days, factory free days, or similar), parameterisation of switching outputs and time changes Programming of holidays (vacation program), special days (e.g.Programming, automatic or manual relay activation.Slave clock output short-circuit-proof and overload protected.

Traditional impulse output 0.5 A for control of hard-wired slave clocks via 24 V DC minutes-, ½minutes- or seconds impulses (connection of up to 50 impulse slave clocks).Checking-LED’s for power supply (green) and alarm (red).2-lined LCD display for indication of hours, minutes, seconds and date respectively menu guide in program mode (2x 24 characters).

In case of no radio signal the slave clocks are running with their quartz time base without interruption (max.4 different, coded channels for avoiding interferences of several wireless clock systems.Safety in operation through coded time telegram thus no interferences with other systems.Power supply of radio transmitter via master clock.Radio transmitter for unlimited quantity of radio slave clocks inside reception area.Automatic adjustment of the wireless clock system after mains failure.Automatic adjustment of master clock time at installation.Wiring with control cables not necessary!.Microprocessor master clock, fitted with external radio transmitter for wireless communication with unlimited analogue and digital radio slave clocks of series BTWL.
