215U-2 WiFi I/O

215U-2 WiFi I/O

Eaton is proud to announce the release of the 215U-2 Wi-Fi I/O Gateway solution. The 215U-2 brings a simple web-based user interface, utilizes a standards-based wireless protocol, introduces an innovative networking topology, and is sold at a significantly lower price point. Customers do not need a strong background in networking to set up a 215U-2 system. The 215U-2 can be added as part of a customer’s existing wireless infrastructure. This allows the 215U-2 to be sold through multiple types of channel partners into both process and factory automation applications. It provides unique, cost saving features that not only reduce cost, but allow for reduced panel sizes and a smaller amount of control panels in a customer application.
