Ubiquiti USL-Relay SuperLink Relay I/O Module

Proprietary SuperLink12–48 V DC supply requiredI1/I2 dry contactO1/COM/O2 dry contact

The Ubiquiti USL-Relay is a white SuperLink relay I/O module for integrating third-party dry-contact sensors and signalling devices with a UniFi Protect system. It requires a separate SuperLink Gateway and suitable 12–48 V DC supply.

Best For: For installations that need a SuperLink-connected dry-contact interface for third-party sensors or signalling devices, and where a separate Gateway, UniFi Protect system and suitable DC supply are available.
Before you order: A separate SuperLink Gateway, UniFi Protect system and 12–48 V DC supply are required. Check dry-contact compatibility and load voltage/current limits with a qualified installer. The relay switches an externally powered circuit; its DC power input and output load ratings are different.

What's in the Box

  • One Ubiquiti USL-Relay relay module
  • Wall/adhesive plate
  • DIN rail mount
  • Two wall plugs
  • Two M3 screws
  • L-shaped tool

What It Means in Practice

  • Choose a suitable 12–48 V DC supply for the VDD/GND power terminals; the output load ratings do not describe the device’s DC input.
  • The I1/I2 inputs accept dry contacts only. The O1/COM/O2 terminals switch an external circuit and do not supply voltage to that load.
  • Mounting options are adhesive, wall or DIN rail; check the installation location against the 0–40°C and 10–90% non-condensing operating limits.
  • The stated range is up to 2 km and is conditional on the environment; the EU and US frequency entries are separate regional options.

What Will Not Work

  • A separate SuperLink Gateway and UniFi Protect system are required; the module is not standalone.
  • A separate 12–48 V DC supply, external sensors or signalling loads, and connection wiring are not included.
  • Inputs and outputs are dry-contact only; the relay does not generate supply voltage for the external load.
  • Output rating: 10 A per port; UL total maximum 12 A, IEC total maximum 16 A. Respect the applicable aggregate limit.

Frequently Asked Questions

Can it work without a gateway?
No. A separate SuperLink Gateway and UniFi Protect system are required.
Is a power supply included?
No DC supply is listed in the confirmed package contents. The module requires a separate 12–48 V DC supply.
Does the relay power the connected load?
No. Its outputs are dry contacts that switch an external circuit; the relay does not generate the load’s supply voltage.
What is included?
One relay module, wall/adhesive plate, DIN rail mount, two wall plugs, two M3 screws and an L-shaped tool. The Gateway, DC supply, external devices and wiring are separate.
Singular Expert Insight

Its dry-contact inputs and outputs provide an interface between compatible external circuits and a UniFi Protect system over proprietary SuperLink. The rated output load voltage is separate from the relay’s 12–48 V DC power input.

Buyer’s Guide

✓ Buy it if For installations that need a SuperLink-connected dry-contact interface for third-party sensors or signalling devices, and where a separate Gateway, UniFi Protect system and suitable DC supply are available.
✕ Skip it if A separate SuperLink Gateway, UniFi Protect system and 12–48 V DC supply are required. Check dry-contact compatibility and load voltage/current limits with a qualified installer. The relay switches an externally powered circuit; its DC power input and output load ratings are different.
