Narrow band 300mW multi channel transceiver 70TRX-TP1
The 70TRX-TP1 is a professional 300mW narrow band multi channel transceiver according to EN 300113.
The transmitter is produced by default for the European ISM band at 433/434 MHz. All 139 channels from 433.0625 to 434.7875 MHz are programmed in a 12.5 kHz raster. The adjustment of the frequency is predefined for the user in a simple manner in multiples of the channel raster. Therefore, complex programming of the transmitter module is not necessary. A DIP switch or simple soldering bridges are sufficient. The integrated micro controller generates a serial data protocol from the 8-bit data word which sets the synthesizer. Up to 256 channels can be pre-programmed on customers request.
The module is available for most of the worldwide used frequency bands in the 400 MHz range. Please ask us for details. Due to the wide range of our filters, very few variants are sufficient.
The direct audio signal output doesn`t restrict in any way the nature of the desired signal or code transmission. The transmission of digital data works just as well as analog audio or voice signal. Fast switching between TX and RX mode allows the transmission of complex data sets.
The module is characterized by an extraordinarily high selectivity, which makes it possible to operate several devices in close proximity in terms of space and frequency. The excellent input sensitivity also enables signal transmission even over very long distances. The combination with another 70TRX-TP1 offers the user a perfect radio system with long distance communication at half-duplex. Together f.e. with our remote control unit FSM24 the user can expect a free field range of more than 4000 m
