About Ubiquiti Relay, Compact SuperLink Relay Designed I/O Interfaces, Seamless Integration, third-Party Sensors, Signaling Devices.

The Ubiquiti USL-Relay is a compact wireless relay module that bridges third-party sensors, alarms, and signalling gear into your UniFi Protect system. With two dry contact inputs and two relay outputs, it lets you turn almost anything into a trigger and almost anything into a response — think gates, lights, locks, sirens, and doorbell chimes. It's small enough to tuck into a switchboard and tough enough for serious installs.

Key Features

• Dual Dry Contact Inputs — Monitor door and window contacts, motion detectors, light switches, push buttons, or feedback contacts from other gear.
• Dual Relay Outputs — Dry contact terminals rated for 12 to 48V DC or 12 to 240V AC at up to 10A per port, so you can switch seriously heavy-duty equipment.
• Long-Range SuperLink Wireless — Ubiquiti's proprietary SuperLink protocol delivers up to 2 km of range with 14 dBm TX power, seriously handy for spread-out sites.
• UniFi Protect Control — Each input and output is configured independently, and outputs can be linked to input actions or run through Alarm Manager.
• Flexible Mounting — At just 50 x 47.6 x 28 mm with adhesive, wall, and DIN rail mounting, it fits control cabinets and tight spaces without a fuss.
• Wide Power Input — Runs on 12V, 24V, or 48V DC with integrated over-temperature protection at 85°C, so it slots into existing power setups.
