Overview
The Watchdog 100 provides remote environmental monitoring and alarming capability needed to
detect climate conditions in data centers. Additionally, the Watchdog 100 provides one output
relay that can be operated remotely or set to automatically open or close based on alarm
conditions. The Watchdog 100 is equipped with a built-in web server with a 10/100 Mbps
connection speed. Web pages are generated by the unit to monitor local environmental
conditions. No software other than a web browser is required for operation and several data
formats are available. The Watchdog 100 has a built-in sensor to monitor temperature, humidity
and dew point, as well as one port for adding remote sensors. The Watchdog 100 also has four
I/O ports for connecting additional external 5Vdc sensors such as Water and Door Sensors. The
Watchdog 100 can be optionally configured at the factory to support Power-Over-Ethernet (PoE).
