Plexus Controls Inc.

- Model IWS - Intelligent Wireless Ethernet Hub


The Intelligent Wireless System (IWS) nodes comprise of a range of distributed wireless products from Plexus Controls
providing advanced supervisory, control and data acquisition (SCADA) functionality for commercial and industrial
applications. With 'out the box' auto mesh wireless functionality, IWS nodes can be easily installed at a remote location and connected to standard sensors, supporting 4-20mA or 0-5V. Either through a direct wireless connection or automatically hopping through a series of other IWS nodes, the sensor data is relayed back to the IWS Hub for termination over Ethernet to the IWS Management Server application for display, logging and alarm management.

A network of IWS nodes can scale to over 1000 nodes and be supported by one or more IWS Hubs.

In addition to the basic IWS node supporting up to 4 standard SCADA inputs, several variants are available, offering output controls through dry relay contacts and/or 12V DC output to facilitate motor, solenoid valve, contactor operation or other peripheral controls

All IWS nodes can be configured to include local powering options. These include battery (primary or backup), solar and
micro generator options such as from induction and vibration sources.

The IWS Management System (MS) application provides a single point for managing all IWS sensors. An IWS network can be managed using a user friendly GUI stand-alone solution or through standard interfaces such as Modbus and DNP3.
