Expert Sensor Box 7214 Series

Stand-alone LAN sensor for environment and I/O monitoring

Expert Sensor Box 7214 Series allows environment monitoring of IT installations over TCP/IP networks. There are three models available, that contain integrated sensors as well as two sensor interfaces for extended monitoring. Depending on the device model, temperature, humidity and air pressure can be measured. The three sensor models are also available in a Power-over-Ethernet (PoE) version.

Further more the devices dispose of a switchable relais output and a passive signal input, enabling remote control of connected NO and NC appliances. SNMPv3, SSL, IPv6 and Telnet, Radius and Modbus TCP support are incorporated into Expert Sensor Box 7214 Series.

The LAN sensors are also available in versions without I/O monitoring as Expert Sensor Box 7213 Series.
