The information is output as a 4-bit word via CMOS outputs for further use. As long as valid data is being received, the corresponding outputs of the receiving module remain active and are immediately turned off upon receiving the off signal. If the off signal is not received due to a radio interruption, the outputs of the receiving module remain active for an additional 1.5 seconds after the data reception ends. In addition to the digital outputs, an analog output is available to transmit the sent analog value. The modular and compact design with pins spaced 2.54 mm apart allows for flexible use in a wide range of applications. To implement a command from a transmitter, it must first be taught to the receiving module once. Depending on the preference, up to 60 transmitters with all buttons or individual transmitter buttons can be learned into the receiving module. Outputs, for example for controlling LEDs and a piezo speaker, provide information about the function and transmission behavior and indicate the status of the power supply of the transmitter and the receiving module. For applications with limited power supply, a power-saving mode is available. In this mode, the receiving module operates in a pulsed manner, significantly reducing power consumption. Using an analog input, for example, the supply voltage at the receiving module can be transmitted to the transmitter. The level of this analog value is displayed at the transmitter in three stages. The radio modules of the SH-12 series operate with extremely low interference due to their special transmission characteristics. With interference-resistant radio transmission and extremely short reaction times, ranges of over 1000 m can be achieved. For strong narrowband interference or the use of multiple parallel radio systems, the operating frequency can be adjusted to individual needs. The SH-12 radio series can be operated in both unidirectional and bidirectional modes.
