[Introduction]：The wireless intercommunication switch is a terminal device that uses LoRa modulation technology to achieve wireless remote transmission of switching values. It supports collecting switching inputs (DIs) and controlling relay outputs (DOs). Operating in the 850.125-930.125 MHz frequency band, its core function is to achieve 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.
