The NIO51 is a rugged, cost-effective industrial Wi-Fi Mesh adapter/router that supports bridging and routing data between various wired and wireless communication interfaces.
MODBUS connectivity supports bridging between:

  • MODBUS/RTU to MODBU/TCP – wired
  • MODBUS/TCP Ethernet to Wi-Fi

When operating in transparent mode it supports connectivity and bridging between:

  • Serial RS232/422/485 to Wi-Fi
  • Serial RS232/422/485 to Ethernet
  • Ethernet to Wi-Fi
  • Serial connectivity with baud rates up to 921.6 kbps
  • Serial buffering with 20 MB of on-board storage

Wi-Fi can operate in Mesh and Client router modes allowing for various deployment models. It supports Wi-Fi Mesh and 802.11 a/b/g/n connectivity and hosts 2x2 MIMO antenna technology for increased throughput and robustness to interference.

It is rated for operation in the -40 to +70 ° extended temperature range and can be powered by a wide range of powers supplies from 12 – 48 VDC.

State-of-the-art secure data transmissions are ensured through advanced encryption and authentication schemes. Web-based security management and configuration is intuitive, user-friendly and versatile, especially when combined with the nCare I4.0 network manager.

All software and firmware components are remotely upgradeable.
