[Introduction]：The wireless intercommunication switch is a terminal device that uses LoRa modulation technology to achieve wireless remote transmission of switching values. It supports four digital inputs (DIs) for data acquisition and four relay outputs (DOs) for control. Operating in the 850.125-930.125 MHz frequency band, its core function is to enable remote synchronous control. It requires no wiring and is highly user-friendly, allowing users to quickly integrate it into their own systems. It accepts a DC input voltage of 8-28 V. It is coated with a conformal coating that is resistant to mildew, moisture, and salt spray.
