Whenever there is a failure in GPS signal, GPS receiver functions along with master clock. master clock works as stand alone clock, it keeps on providing time transmission which is used for wide range of application including to drive diverse slave clock and for setting time stamping for a long distance. GPS receiver is designed in such a manner that it can be easily synchronized with IST/UTC by using time signal from frequency NPL (National Physical Laboratory) and GPS.

Salient features:

• Configured to work as stand alone clock
  
• Can be synchronized with GPS to drive any number of slave clock / digital Clock for whichever distance
  
• Can work without power for longer duration
  
• Dual Display namely LCD/LED

Rooftop GPS:-

Our range of rooftop GPS with Master Clock has inbuilt IP66 enclosure that can work in any weather condition to provide time format for which ever distance. In case of redundant operation, Master Clock is capable to accept 3 to 5 Rooftop GPS; it is well suited for SCADA operation where there is need of enormous Quantities of Synchronization to various RTU based system.

Distribution Panel:

The time and frequency distribution panel consist of redundant GPS / Redundant Master Clock / Redundant Power Supply / Redundant Battery Charger for Power Sector / Generation Plant to distribute Time and Frequency for various location. Sertel can provide Time Display with various character size Analog / Digital to display at various location.
         
Various type of Signal Output, we can give any number of quantity on each output in different signal can be provided for synchronising the time events and also Time Stamping for Instrumentation Product, Electricity Products and various Networking of Computers on the network can be provided. The Frequency display with 3 decimal (49.786Hz) with integrated for timing such as 15/30/45/60 Minutes of facilitate grid tariff. The display can be provided at any location with different characters Syntheses Frequency Output for our calibration both Time and Frequency based products with any type of frequency available as calibration Source reference to atomic Clock.

GPS Satellite based Time Synchronization and Frequency System to distribute Slave Display of Analog / Digital / Etherner based Clock.

Display:- Analog / Digital - Any Size - Any Distance

Time Synchronization Equipment:- Time Synchronize to Electronic Instruments / Computers. Any type of Outputs and any distance of Display and also Network based WAN / LAN System to Time Synchronize.

We are into the manufacturing of frequency display that works with GPS / master clock to exhibit precise frequency by means of three decimal for tariff meter frequency based metering. This operates with precise time that is sourced from GPS of atomic clock to produce standard 50 Hz. It also offers variation of frequency for the power production and distribution unique element such as integration of time, for example 15 / 30 / 60 minutes meant for healthiness of fabrication and distribution by more profitable of power billing on grid based frequency display.

We manufacture video time inserter that can be synchronized with GPS / master clock / IRIG; it is widely used for building automation on security purpose and in CCTV application for the analysis of picture. Another feature of video time inserter is that any number of monitors can be synchronized to it.

Annunciator Panel:

The SER-3000 Annunciator Panel is an advanced annunciator panel that allows complete alarming, notification, event recording, reporting, and communication. The SER-3000 supports the standard ISA-18.1 annunciator sequences and also any customized sequence based on the customer needs. Alarm monitoring capabilities of 4 to 1000 windows that can be independently programmed to alarm through contact inputs or communications. The SER-3000 is designed to read and acknowledge alarms locally or remotely.

The control inputs can be ordered to any of the standard control input voltages found on station battery systems. Each input has programmable time response settings to help ride through false operations of connected equipment. The outputs are all continuous-carry contacts. The contact can be used to trigger-on critical or non-critical alarms that can be used for hooting. The contact can be used to connect a strobe light or large display LED to trigger off any of the alarm points. All kinds of FACIA window sizes are supported.

Standard Features:

•  ISA-18.1 annunciation sequences: A, M, R, F1A,R-12
•  Capabilities to handle 4 to 3000 number of inputs and outputs
•  Serial ports, TCP/IP outputs available for communication with other devices.
•  Internal power supply 48 Vdc or 125/250 Vdc or Vac
•  IRIG-B input with 1 ms SER time-stamping for Event Recording
•  Programmable  PC software interface
•  Front panel alarm points with configurable
• windows and indicating LED labels
•  Modbus RTU, MIRRORED BITS, SER ASCII and Compressed ASCII, and Ymodem file
• transfer protocols
•  Event Messenger Compatibility
•  Remote Data Monitoring  and Report Generation Compatibility
• Have flexible configurations for input and output side.

Our range of digital / ethernet slave clock offered by us displays Hours/Minutes/Seconds. It is designed to work at any distance connectivity either through Cables / Wireless /Network / PLCC as per the need with GPS Receiver / Master Clock / Rooftop GPS. To have ideal viewing angle for big enterprises, Slave Clock is fabricated in such a manner that it can be attached in 1-Side / 2-Side / 3-Side / 4-Side. These are available in a wide range of colors to bring attraction. Apart from manufacturing standard range, we also offer our customers the facility of customizing it as per their specifications.

Digital / Analog:

For many application like malls / Educational Institutes / University /Building Automation / Tower Clock / Railways Sertel can give any types of Display with different Sizes. For various application Synchronized to either Master Clock or GPS Clock or Both.

Salient future of the system to drive any distance and also or number clock with well Isolated Signal.

Sertel can incorporate various timing alarm for various application either in master or in slave clock or our both clock of different timings. Sertel can given alarm or voice annexation with high volume for any such application.

Diode-O-Ring / Power Supply:-
 
An isolated power supply that works in the range of 90 to 260 AC/DC. It is designed in such a manner that it can take 2 input in case of AC and DC delivered from one output to bigger distribution of current potential of 5V/12V/24V DC operation meant for   functionality of electronic circuitary as redundant configuration power supply.

Signal isolator offered by us is equipped with optimum accuracy meant for interfacing with Analog Data Acquisition, Tele-metering and Process control application. For DIN rail/wall mounting, it has flame retardant polycarbonate. Transducers / transmitters alter one type of energy to a load free DC current which can be carried by economical cables similar to telephone cables to extended distance that can be fed into numerous indicators, recorders, controllers or analog to digital converters at diverse places.

Signal booster and signal conditioner offered by us has the capability to transmit the data to big distance without any sort of time loss in case of the recipient side such as RS232 / RS485 / TCP/ IP / IRIG-B /potential free contact / pulses / BCD application related to time.

We manufacture automatic vehicle locator with in-built GPS track vehicle. It can be attached to any type of network for remote monitoring with option also available for mapping. Apart from this, we also have expertise in GIS mapping.
