GLR2708
8-Channel 27MHz Gigalink™ Receiver with Open Collector Outputs

Features

• Wide supply connection – 10.0 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.
• Eight open collector outputs. All outputs can be operated
simultaneously.
• Crystal controlled for high stability and performance.
• Uses micro-controller technology that can be re-programmed
to suit unique applications.
• Momentary, latching and security latching output modes is user
selectable.

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 GLR2708 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 and ability to program any
number of transmitters to a receiver adds up to the most advanced and secure Remote Control available

Code Programming

For code programming, please refer to the separate programming instructions.

  • Page 6 ELSEMA 8-Channel 27MHz GIGALINK™ Receiver with open collector outputs, GLR2708 Application Notes (GLR2708) Care should be taken with the solid-state outputs that they are protected from inductive loads. This is done by connecting diodes across your DC inductive load. Inductive loads such as DC relays must be clamped with a diode across the relay coil. If this is not done the spikes generated by the DC relay can lock-up the receiver.
