The Tunwall Radio TRC-2A controller is an FM or non-directional AM controller. It is designed for two coaxial switches or 120V AM contactors, two or three transmitters and two antennas. The key switch selected auto function will transfer to the aux transmitter upon failure of the main transmitter. 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-2A 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-2A is compatible with all standard coaxial switches, and can also be used with RF contactors or an aux antenna for non-directional AM stations.
