Detect AC voltages from 20 to 250 VAC. 50- 250 VAC sensor for the Environmental Monitoring System. The Environmental Monitoring System Hub is an affordable way to monitor smaller installations. It acts as the central hub of the environmental monitoring system in limited areas. Connect it to your network attach Environmental Monitoring System sensors and you're ready to remotely view the status of your data centers and other facilities. Choose monitors for temperature humidity power or liquids. Or know when server cabinet doors are open or closed and whether the cabinet is overheating. Use it for remote monitoring and management of devices such as HVAC systems security equipment UPSs generators and industrial equipment. These Hubs feature autosensing RJ-45 ports for connecting any of the Environmental Monitoring System Intelligent Sensors. Also available are Hub Kits which include a hub and a sensor. The Hub is smart. Its embedded Web server enables you to use a standard Web browser to view sensor status over any IP network even the Internet. Check out the status of your data center from your office from home or from the road. It's fully SNMP manageable so you can integrate it easily into any SNMP-managed network and monitor it through standard SNMP software such as HP OpenView. The built-in database maintains a time-stamped log of all events so you can go back to see what happened and when it happened. The integrated data collection and graphing package is especially useful in spotting trends in security detection of AC power line voltage measurement of DC voltage and control relays and for providing historical information for analysis. In addition to enabling you to passively monitor sensors the Environmental Monitoring System Hub actively alerts you when sensors exceed limits you determine. It can send alerts via SNMP or by e-mail. The Hub installs in minutes. Simply assign an IP address and connect to the embedded Web server. Plug in one or two of our Intelligent Sensors and the Hub's autosensing feature will recognize the type and automatically configure it.
