Intelligent Wireless Ethernet Hub

Our Intelligent Wireless System (IWS) nodes provide advanced supervisory, control and data acquisition (SCADA) functionality for commercial and industrial applications.

With ‘out the box’ auto mesh wireless functionality, IWS nodes are easily installed at a remote location and connected to standard sensors, supporting 4-20mA ,  0-5V and internal integrated pressure and depth measurements.

The data is securely stored on site on the IWS Hub and can be retrieved and archived using FTP. In addition, the hub continues to provide real-time data access.
