Plexus - Intelligent Wireless SCADA Distributed Control System Air Analysis System
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 and low power requirements, the IWS Air Analysis System (AAS) can be easily installed at a remote location and connected to multiple ground probe sampling tubes at different heights. The IWS AAS wakes up 4 times a day (programmable) and using an internal compressor to draw an air sample from each of the ground probes in sequence and takes a gas reading.
The readings are sent over a mesh wireless system to an on-site hub unit where they are time stamped and logged. Data may be downloaded from the hub site on a regular basis (programmable) or continuously monitored in real time over a WAN connection such as a cell modem. Users can log into the gateways internal server to view the data and set up email/sms alarms.
A network of IWS nodes can scale to over 1000 nodes and be supported by one or more IWS Hubs.
In addition to the IWS AAS system IWS product family support up to 4 universal SCADA inputs including powered 4-20mA loop, differential pressure, serial, DC analog and 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 the Plexus NMS or through standard protocol interfaces such as Modbus.
