BASIC TYPE DIVISION:
Master clock D201 is available in:
- Standard - STD, with mp3 player - MP3, with power backup - UPS, for use in big time distribution systems - MAX
- Rack - RQ or wall -mounted - PQ version
- Input slot for GPS receiver and C232 interface to connect with PC.
- Master clock with interface 485 can be synchronized from NTP using D213 converter
NOTE: GPS input can be used to connect GPS or DCF receiver.
D201RQ/UPS CHARACTERISTICS:
- 1 slave link - suitable for small time distribution systems
- ACTIVE ENERGY BACKUP with accumulator 2x12V/2.2Ah. During power cut system remains operational (including slave clocks)
- Metal casing compatible with 19 inches rack system or table version with shorter front panel to be situated on the table.
- Can work independently, without synchronization from outside.
- Input for GPS receiver. It is assumed that a GPS receiver will be used, which will ensure constant high accuracy. For example GPS receiver D910SQ. A suitable receiver is the D610SQ. The D213 converter can be connected to the input for synchronization from NTP, if the master clock does not already have this input.
- All master clocks, as well as SONTEK digital clocks, have an optional Ethernet input with the ability to obtain accurate time from two selected NTP servers.
- C232 interface to connect with PC. It is possible to use USB virtual COM converter.
- Synchronization
from link 485 can 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
- One slave polarized link 24VDC (minute or second)
- Active energy backup
- Rack version
- 35W power supply (one slave line)
C485 INTERFACE:- NO - interface is not used
- YES - It is possible to synchronize connected devices (digital clocks, other master clocks ) or be synchronized from another device.
VERSION:- RACK - compatible with 19" rack system. Handles are used.
- TABLE - front panel is shorter. Handles are not used. Better version to be situated on a table or shelf.
SLAVE LINK:
- 1X - at least one link is always used.
- 2X - used with stronger power supply (60 W)
- 3X - used with stronger power supply (60 W)
NOTE:
Each slave polarized link is for voltage 24 VDC and has electronic current overload protection set to 0,5 A. Selection of minute/second mode with
jumper on link board.
RELAY:
- NO - not used
- RELAY1 - One contact switch voltage 24 VDC (e.g. for engine bells). Other contact is made separately (marked as RELAY1 NC).
ADDITIONAL SYNCHRONIZATION
- NO - The input is not used
- IMPULSE SLAVE LINE NPUT - The slave line input is used. It allows to synchronize one or more the master clocks from other SONTEK master clock. The slave can use the minute mode with the ML01 protocol, but even more preferred is the second mode with the SL02 protocol (time and date are transmitted every minute).
- NTP - The master clock is equipped with an Ethernet input with the possibility to synchronize time from two selected NTP servers.
THERMOMETER INPUT:
- NO - not installed
- YES - it allows to connect thermometer (e.g. D111SQ). TInformation about temperature can be distributed into slave clocks using C485 or second polarized link.
8xRELAY MODULE
- NO - not installed
- YES - enables to switch 8 relay based on time settings. 24V voltage use only.
LAN MODULE
- NO - not installed
- YES - Remote control through LAN with MonTIME PC application (for windows).
