Digital Flameproof Synchronized Clocks

Digital Flameproof Synchronized Clocks

Salient Features:

Flameproof Digital Synchronized Clocks are housed in Aluminium LM- 6 Body Certified by CIMFR, Dhanbad for use in Gas Group Areas I, II, II A & II B. The Flameproof Master & Slave Synchronized Clock Systems work on wired RS485 Modbus Communication & optionally on Wireless RF Communication.

Wired RS 485 Communication:

In the wired RS 485 communication, the slave clocks (upto 120 Nos.) can be connected to the master clock via a 2 core communication cable multidrop network & the master clock time is synchronized with all the slaves. The Master clock can be an Ethernet Master Clock ( which communicates with the Server Time ) & the same server time is transmitted to all the slave clocks over RS 485 wired communication . Optionally, the Master Clock can be a GPS Clock, which takes time directly from the GPS Satellite network & the same GPS accurate time is transmitted over RS 485 wired communication to slave clocks Upto 120 Clocks can communicate over RS 485 Wired communication network.

Wireless Radio Frequency (RF) Communication:

In the Wireless RF communication, the slave clocks ( upto 108 Nos.) can be connected to a single master clock without any need of communication cabling. The Master Clock time is automatically updated every second with the slave clocks over Wireless RF communication using the free to air 865 MHz radio frequency. The Master Wireless RF clock can be an Ethernet Master Clock ( which communicates with the Server Time ) & the same server time is transmitted to all the slave clocks over wireless RF communication.

Optionally, the Master Clock can be a GPS Clock, which takes time directly from the GPS Satellite network & the same GPS accurate time is transmitted over Wireless RF communication to slave clocks In the wireless RF communication clocks , the Master Clock talks to the nearest slave clock & this slave clock , in turn, talks to the next slave clock, thus forming a Wireless Mesh Network. In the Wireless RF Mesh Network, the Master clock can be anywhere & the slave clocks form a mesh network among themselves, thus increasing the distance of communication. Standard range of wireless communication is upto 1 Km. line of sight
