Ubiquiti SuperLink Relay USL-Relay - sieťová automatizácia suchý kontakt relé, PoE/USB-C, UniFi spravované

Most smart relays force you into proprietary hubs or separate power bricks, but the Ubiquiti SuperLink Relay USL-Relay strips that clutter away. This compact network automation relay delivers a single galvanically isolated dry contact in a rugged polycarbonate enclosure, powered directly by 802.3af/at PoE or USB-C. With under 1 W consumption, it slots seamlessly into any UniFi deployment, enabling remote switching of door strikes, gates, lighting, and more.

Highlights

• Single dry contact relay with both NO and NC terminals for flexible integration
• Switches up to 250 V AC or 30 V DC at 10 A, suitable for door strikes, gates, or lighting
• Powered by 802.3af/at PoE or 5 V DC USB-C, eliminating separate relay power supplies
• Managed entirely through the UniFi Network Application with remote operation and scheduling
• Robust polycarbonate housing with magnetic or screw wall mounting and wide operating temperature range

In daily use

Installation is straightforward: connect the relay output to your controlled circuit, provide PoE from a UniFi switch or injector, and adopt the device in the UniFi controller. From there, you can toggle the relay manually, create automated rules based on time or other UniFi events, and monitor status remotely. The relay's dry contact design ensures electrical isolation, protecting both the SuperLink and the connected equipment. Its compact size and magnetic mount allow placement inside enclosures, on metal surfaces, or on walls without extra hardware.
