[Introduction]:EWD95M-433N30(485) is a wireless data transmission radio based on narrowband transmission technology. It has the characteristics of strong anti-interference ability, half-duplex, integrated transceiver, transparent transmission, etc. It works in the 425~450.5MHz frequency band (default 433MHz) and supports intercommunication with our E30 series modules. The radio provides a transparent RS485/RS232 interface, adopts a plastic shell, a guide rail installation structure, and supports 8~28V (DC) wide voltage input. The product is sprayed with three anti-paints, with "anti-mold", "anti-humidity" and "anti-salt spray" functions.
