Güde Expert Sensor Box 7214-11 PoE Environmental Monitoring Unit, 2x Sensor Ports, Relay Output, Digital Input

Power over Ethernet meets precision environmental monitoring in the Güde Expert Sensor Box 7214-11. This compact unit draws its power directly from the network cable (IEEE 802.3af Class 1), eliminating the need for separate power supplies and simplifying installation in remote or difficult-to-reach locations. With two analog sensor ports, a potential-free relay output, and a digital input, it extends your Didactum monitoring system to cover temperature, humidity, water leakage, smoke, motion, and door contacts—all managed through an intuitive web interface.

Overview

The Expert Sensor Box 7214-11 is a network-attached environmental monitoring unit that connects via standard 10/100 Mbit Ethernet. It features two RJ11 sensor ports for analog sensors, one relay output for controlling external devices or alarms, and one digital input for dry contact integration, such as door switches or fire alarm panels. The device supports a wide range of communication protocols including HTTP(S), SNMP v1/v2c/v3, SMTP, Syslog, NTP, DHCP, and FTP, ensuring compatibility with existing IT infrastructure.
