[Introduction]：The wireless intercommunication switch is a terminal device that uses LoRa modulation technology to achieve remote wireless switching value transmission. Operating in the 850.125-930.125 MHz frequency band, it supports four digital inputs (DIs) for data acquisition and four relay outputs (DOs) for control. Its core function is to enable remote synchronous control without the need for wiring, offering high ease of use and enabling quick integration into users' systems. It accepts an 8-28 V DC input and is coated with conformal coating, offering anti-mold, anti-humidity, and anti-salt spray properties.
