Master clock D204 is available:
- SQ (22W power supply), PQ (63W power supply including 75VAC for older bell types)
- Without slave link or with slave link
- Input slot for GPS receiver and C232 interface to connect with PC.
- Master clock with interface 485 could be synchronized from NTP using D213 converter
NOTE: GPS slot could be used to connect GPS or DCF receiver.
D201RQ/MAX CHARACTERISTICS:
- master clock without slave link or with one slave link suitable for bell switching in small schools and for small time distribution systems (with slave link).
- Passive energy backup - internal
time of master clock is working during a power cut, but analog slave
clocks are stopped. Analog slave clocks will be set up automatically
after renewing the electricity supply
- Metal wall-mounted casing.
- Size 183x164x67 mm.
- Input slot for GPS receiver. Should be connected to provide high accuracy. For example GPS receiver D910SQ.
- C232 interface to connect with PC. It is possible to use USB virtual COM converter.
- Synchronization
from link 485 could be added. It is bi-directional interface. It is
possible to use to set up slave clock with time from master clock or to
set up master clock time from superior master clock device.
- The master clock can be extended with a wireless DHF system with D216 converter.
MINIMAL CONFIGURATION
- Two relays programmable according to time. RELAY1 switch voltage 24VDC to output connector for bells. RELAY2 switches contact without voltage.
- Input slot for GPS receiver. Should be connected to provide high accuracy. For example GPS receiver D910SQ.
- C232 interface to connect with PC. It is possible to use USB virtual COM converter. Remote control through LAN with MonTIME PC application (for windows).
CONFIGURABLE OPTIONS
SLAVE LINK:
- NO - not installed
- YES - One slave link is use to manage slave clocks (up to 20 pieces) . Could work in minute or second mode.
NOTE: Each slave polarized link is for
voltage 24 VDC and has electronic current overload protection set to 0,25 A.
Selection of minute/second mode with jumper on link board.
ADDITIONAL SYNCHRONIZATION:
- NO - not used
- C485 - It
is possible to use to set up master clock time from superior master clock device or to synchronize slave clocks.
- INPUT SLAVE LINK - to synchronize master clock time from superior SONTEK master clock
