- 1 - 

GLR2703, GLR2704 

Multi-Channel 27MHz Gigalink™ Receiver 

 
Features 

• 3 or 4 Channels  
• Wide supply connection – 11.0 to 28.0 Volts AC/DC  
• Highly sensitive receiver input stage. When used with GLT27…. series 

transmitters and an ANT27L antenna, an operating range of 350 metres (980 ft) 
is possible.  

• Three (GLR2703) or Four (GLR2704) relay outputs. All outputs can be operated 

simultaneously.  

• Crystal controlled for high stability and performance.  
• Dual Conversion to reduce interference.  
• Uses micro-controller technology that can be re-programmed to suit unique 

applications.  

• Momentary, latching and security latching output modes is user selectable. 
• Power ON LED indicator. 
• Test buttons for relay. 

 
Applications 

• Automatic gates, security, timer controlled outputs and simple on/off functions etc

Description 

The GIGALINK™ is an advanced Remote Control technology available in the world today. GIGALINK™ is an 
invention that has revolutionised the entire Remote Control technology including Elsema's earlier version of FMT- … 
and FMR- … series. The GLR.... series state-of-the-art invention brings a new dimension in the world of Remote 
Control technology in domestic, commercial and industrial applications. 
 
The innovative microcontroller technology replaces the traditional dip switch coding which eliminates any possible 
code grabbing. Special features such as over four billion code combinations, ability to program any number of 
transmitters to any of the receiver outputs, three user selectable modes, dual conversion superhet and operational over 
a wide voltage range all adds up to the most advanced and secure Remote Control available.
