Long Range Radio Modem : Model TRM 700H

The TRM- 700H Wireless Modem is available with programmable RF power output from 10-500 mw. It is also available in higher power version power output, for longer transmitting distances upto 50 Kms
The TRM-700H is compatible with a variety of communication protocols:
MODBUS-RTU, MoP (an enhanced version of MODBUS, optimized for radio communication), Siemens 3964R, ASCII, and Transparent Mode. Any of these can be selected by the user via DIP switches. RS-232 or RS-4_5 serial data interface is available. RF power output limit is user adjustable (within the specified power rating of the unit). Field strength of the received radio signal is indicated by an LED array.

Model RAR-700is special version that functions as a radio repeater station. It can re-transmit standard MODBUS-RTU and MODNET-IF protocols.

Easy SCADA System Integration with MODBUS

The FTR-700H/P8 is particularly suitable for integration with SCADA systems that support the MODBUS-RTU protocol. The normal SCADA software can directly access the MODBUS registers of the FTR-700H/P8 through a wireless modem. Up to 255 Wireless Remote I/O Modules can linked together in a single radio network.

Concept :

King radio control. range of products are Radio communication based remote terminal unit & modems which allows you to transfer status, control and measurement signals from remote site to central control room. Latest Radio based systems of today allow convenient and more reliable wireless controls far beyond the boundaries of rooms and buildings without the need of expensive cabling and site preparation work. Specially designed for harsh industrial conditions RTU 700 can be mounted on fixed or Moving equipment without worrying about Voltages, vibration, temperature and humid conditions.

Typical Radio RTU installations :

Material Handling Area :
FTR 700 is used in stacker / Reclaimer for replacement for CCRD system and assymbly. The necessary boom conveyor interlocks are handled over by FTR instead of cable system. The techno- economics of this system is very good as now You don't have to buy control _cables and drum motor.

Transfer Station :
In this application the RTU 700 is monitoring ala rams and other on/off status indications in transformer stations. Data from electricity meters is partly collected from the pulse via a serial interface to more intelligent devices. The counter values and the profiles can be passed to the main station via radio link

Pipeline Monitoring :
Along the pipeline each pump and flow monitoring station is equipped with RTU 700_1I flow data and alaram data are collected and reported by the RTU 700 to the main station. !n addition several environment measurement such as temp rain and wind data can also be collected and passed to the RTU .

Independent site alarm application
Many sites with critical or high cost must be monitored by independent alarm and monitoring system. !n these applications the RTU offer the function as a Emergency standalone module in case of main controller failure and added with Ups supply RTU becomes highly reliable emergency system

Water supply/treatment :
In this application the TRU is monitoring an unmanned pumping station which pumps ground water from the borewells to the treatement plant. Data such as amount of water pumped running time of pump conditions of filters etc can be monitered and logged. All data are online transfered to the central RTU and in event of failure the RTU shall contact back end and report the problem. In addition with GSM modem it can send the local engg the alarams or SMS the problem which makes the damage control measures fast.
