NIO 51 brings the wireless connectivity from serial devices or Ethernet devices perfectly to Wi-Fi Mesh backbone in smart factories. Thanks for the Wi-Fi Mesh technology, every device connecting to NIO 51 can easily keep multiple Wi-Fi connecting paths to either IWF310 EZ Mesh backbone or neighbor NIO51 devices to communicate with the control center even the devices are in moving status such as AGV application in factories.  


NIO 51 provides flexible conversion between Modbus RTU to Modbus TCP protocols as well as serial to Ethernet/Wi-Fi interfaces within one box. It’s also equipped with high immunity to EMC high level protection in Surge, ESD and EFT, wide operation temperature and redundant power so people do not need to concern about impact from harsh environment. Optional mPCIe port can be used as 3G/LTE WAN connection in the mobility applications or the environments where no Wi-Fi coverage is possible. 


NIO 51 fills the communication gap between legacy edge nodes to the control center, enabling field data to be harnessed for manufacturing process optimization, asset management, and preventive maintenance.
