Tunwall Radio TRC-3



Three-Switch Controller

Contact BSW for your pricing and shipping!

The Tunwall Radio TRC-3 three switch controller is for combined FM transmitter systems. It is designed for three coaxial switches, one antenna and a combiner/injector. Logic for a third transmitter is programmed on this controller. The key switch selected auto function will transfer to separate transmitter 1 or 2 mode if either fails. The dummy load ready light works with the load interlock logic for automatic load protection.

The pre-programmed PLC (programmable logic controller) in the TRC-3 provides control and logic for the coaxial switches and transmitters. The coaxial switches plug into 9-pin AMP connectors on the controller, and transmitter and remote control connections are made to barrier strip terminals.

The TRC-3 is compatible with all standard coaxial switches, and can also be used with RF contactors for non-directional AM stations.
