Using fiber optic enables to use a higher communication bandwidth while offering a total immunity against EMI/RFI interferences and an increased security as well.

 

The optical fibre still offers other advantages : use without risk in an explosive environment, no EMC emission, no ground loops, immunity against lightning and high voltage environments, they are finally lighter, less cumbersome, inert and corrosion resistant ...

 

Plug & Play: RD300 features a self configuration mechanism based on a CPLD component that frees you from the tiresome operation which consists in the serial parameters setup, product is "Plug & Play".

 

RD300 features in standard a built-in system to control the fiber integrity, it reports automatically any failure with an error LED and also setups a relay contact (MOSFET) to activate any external safety device.

 

Its small size, design features and its great adaptability make the RD300 a really universal product capable to satisfy to major needs of the industry.

 

Topologies

Point to point topology

This configuration enables to control a single equipment installed in a very polluted or distant area. The optical line is totally insensitive to EMI/RFI perturbations.

Simple ring topology

This topology enables to build a simple ring whereas the master equipment is installed in the middle.
