The RNM-24 transmitter enables wireless control of receivers of the EXTA LIFE system. It allows the implementation of such functions as remote switching on / off of lighting, regulation of lighting intensity, closing / opening of window blinds and garage doors. It is designed for mounting in switchgears using the TH35 rail. The transmitter has four inputs that trigger 230 V AC. Triggering is accomplished by short-term shorting of a given input with the phase potential or potential of the neutral conductor. The transmitter allows independent control of up to four circuits (channels). Built-in LEDs indicate the transmission and operation of individual inputs. Coded radio transmission ensures control safety.
