The EFB-TRL4 long-range radio system offers a flexible, wireless solution for transmitting digital and analogue signals over long distances between multiple radio nodes. The basic unit is equipped with 4 inputs that can process both digital and analogue signals. It also has 4 outputs that can be factory-configured as either relay switching outputs (normally open contacts) or analogue outputs. Various combinations of relay and analogue outputs can be selected to meet the specific requirements of the application. The ability to integrate various add-on modules means that the basic unit can be flexibly adapted to almost any application, guaranteeing a high degree of versatility. The EFB-TRL4 system is constantly being further developed, with regular firmware updates offering additional flexibility and ensuring long-term investment security.
