8010SD Horn Controller

Series 8010SD Horn Controller, installed in hundreds of LRVs. The controller has a switching power supply that transforms the 24Vor 36V DC nominal input to +/-50V for the power amplifier and 16V for other functions. The controller also has an audio board that stores the digitized signals and a microprocessor that plays them back when required. The third board in the controller is the power amplifier that provides relays that are activated by the horn control switches in the LRV and an audio amplifier to drive the speaker. The relays request the audio board to send the audio signal and provide isolation from the LRV horn control switches. It can be used for external messages as well as horn/bell/whistle sounds. Includes the horn controller and wiring accessory kit.
