[Introduction]：E860-DTU(2020-400SL) is a terminal device that realizes remote transmission of switching values through LoRa modulation technology. It supports 2-channel collection of switching inputs (DI) and 2-channel 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.
