Ubiquiti UniFi Protect SuperLink Relay (USL-RELAY) - physical security relay, white

The Ubiquiti UniFi Protect SuperLink Relay (USL-RELAY) is a security relay designed to add controlled switching to existing systems. It connects to third-party sensors and alarms through dry-contact output channels. Instead of using wired networks, the module communicates via Ubiquiti’s proprietary SuperLink wireless technology, allowing control signals to be transmitted without the need for additional site cabling. The device does not support Power over Ethernet (PoE) and requires a separate 12–48 V DC power source.

The internal components are housed in a white polycarbonate enclosure. Installers can mount the relay using adhesive, attach it to a wall, or secure it to a standard DIN rail. System status is indicated by on-board LEDs: an RGBW light displays the connection state, while white LEDs confirm signal input and relay output. Designed without RJ45 ports, the hardware is intended for integration into distributed automation setups.
