[Introduction]：LoRa distributed IO host series is a powerful wireless remote control and data acquisition device. Utilizing LoRa wireless technology (with a built-in wireless module), it can be controlled by sending Modbus RTU commands via a serial port or a remote LoRa-connected device. It can be used with our company's wireless data transmission radio (E95-DTU (900SL30)) to wirelessly acquire and control digital and analog (DI/DO/AI/AO) input and output signals. The product housing is coated with a conformal coating, offering resistance to mildew, moisture, and salt spray.
