[Introduction]：E860-DTU(4040-400SL) is a terminal device that realizes remote transmission of switching values through LoRa modulation technology.The shell adopts three-proof coating, which is Anti-Fungal, Anti-Humidity, and Anti-Salt Spray. It supports the collection of 4 switching inputs (DI) and 4 control relay outputs (DO). The core of its function is to realize remote synchronous control without wiring. It is highly usable and convenient for users to quickly integrate into their own systems.
