Sonoff MINI-D Matter AC/DC Dry Contact Smart Switch - White

Product Features

• Matter-over-WiFi smart dry-contact relay.
• NO, COM and NC dry-contact terminals for flexible control logic.
• Can be powered by 100-240V AC or 12-48V DC; the two supply types must not be connected at the same time.
• Direct-load output supports low-voltage DC loads only.
• Supports up to 24V DC, 2A resistive direct loads.
• Supports compatible 12/24V DC motors up to 8W.
• Inching and self-locking control modes for gates, access control and automation.
• External switch input for local wired control.
• Direct 2.4GHz WiFi connection for eWeLink.
• Matter compatibility for supported smart-home ecosystems.
• 1 Year Manufacturer Warranty

Application

• Garage door and gate controller trigger inputs.
• Access-control and intercom dry-contact automation.
• Boiler, thermostat or control-panel signal inputs.
• Low-power DC valve or motor control within the specified direct-load rating.
• Remote switching of electrically isolated control circuits.

Safety Features

• Disconnect the power before wiring, and never connect the AC and DC power inputs at the same time.
• Check neutral-wire requirements before purchase.
• Do not exceed the rated current or wattage.
• Install inside a suitable wall box, junction box or enclosure.

Frequently Asked Questions

• What is a dry-contact output?
  A dry contact provides an isolated switching connection at the NO, COM and NC terminals rather than supplying mains voltage to the controlled input.
• Can the MINI-D directly switch a 230V appliance?
  No. SONOFF specifies the direct-load output for low-voltage DC loads only. Use the dry contact to control an appropriately rated external contactor or control input where required.
• Can it be powered from a gate or alarm battery?
  Yes, provided the DC supply is within the specified 12-48V DC input range.
• Can AC and DC power be connected at the same time?
  No. Use either the AC input or the DC input, never both simultaneously.
• Does it need a hub?
  No for eWeLink control. A compatible Matter controller is required if you add it to a Matter ecosystem.
