| The SHR-12 K4 was designed in such a way that its functionality can be adapted to a wide variety of applications when being installed.
The advantage of this series is the very low distortion by other radio services combined with a very large active range of up to 1000m. Furthermore there are two frequencies selectable (433.62 MHz or 434.22 MHz). A great feature is the acknowledgement of the received signal so that the user is able to verify the command at the transmitter's side.
Each radio signal sent by the transmitter of the series SH-12 (up to 60 different transmitters) can switch on or off one or several of the 4 isolated change-over-contacts. The function assignment for the transmission keys or codes is done via a configuration panel. The signal/function assignment allows at the same time to perform additional lock functions or to connect external impulse, code or key switches.
The relay function– impulse, timer, switch or toggle operation and its falling edge delay from 0.1 s to 60 min can be selected via DIP switches for each of the 4 isolated relay change-over-contacts |
