E860-DTU(2020-400SL)A Switching Signal relay module wireless transmission remote control remote synchronous transmission acquisition feedback

[Introduction]：E860-DTU(2020-400SL)A wireless remote synchronization switch is a terminal device that realizes remote transmission of switching signal through LoRa modulation technology. It supports 2 channels of switching input (DI) and 2 channels of control relay output (DO). The core of its function is to realize remote synchronous control without wiring, and is highly easy to use, allowing users to quickly integrate it into their own systems.
