M31-XAXX0800G-L__ZIISOR Antenna Manufacturer, supplying 433MHz 868MHz 915MHz WiFi 5G 4G Fiberglass Antennas, Rubber Duck Antennas, FPC PCB Antennas, Magnetic Antennas

M31-XAXX0800G-L Wireless remote IO module Multi-channel analog/switch quantity acquisition control Built-in wireless module supporting Modbus RTU, wireless remote acquisition (DI/DO/AI/AO).

[Introduction]：The LoRa Distributed IO Host Series is a wireless remote IO module that utilizes LoRa wireless technology (with a built-in wireless module). It supports control via Modbus RTU commands sent through serial ports or remote LoRa networking devices. It can be paired with the E90-DTU(400SL30) wireless data transmission radio for wireless remote acquisition and control of (DI/DO/AI/AO) signals.
