GÜDE 7214-3 Expansion Sensor Box for Temperature and Humidity Monitoring with 2 Sensor Ports, 1 Relay Output, 1 I/O Input

Expand your Didactum monitoring system with the GüDE 7214-3 Expansion Sensor Box, a compact module that adds two RJ11 sensor ports, one potential-free relay output, and one digital input for comprehensive environmental and security monitoring. Ideal for server rooms, laboratories, and industrial facilities, it enables precise tracking of temperature, humidity, and other parameters while integrating with external devices.

Advantages

Seamlessly extend your monitoring network with plug-and-play connectivity to the main unit. The potential-free relay output (24VDC/0.5A) allows direct control of alarms or ventilation systems, while the dry-contact input integrates with door contacts or other sensors. With support for cable lengths up to 100 meters, you can place sensors exactly where needed without signal loss. The module operates from -10°C to +60°C and can be wall-mounted or installed on a DIN rail with an optional adapter, offering flexible deployment in critical environments.
