OXT T224 Mini Wi-Fi Relay Module 4-Channel Tuya Smart Life Dry Contact 10A/Channel

Unlike bulky DIN-rail relays or single-channel smart switches, the OXT T224 packs four independent dry-contact circuits into a compact ABS housing, each rated for 10 A. It runs on Tuya's proven cloud, so you can mix 85–250 V AC and 7–32 V DC loads on the same board without extra power supplies or hubs.

Highlights

• 4 potential-free relay outputs, 10 A per channel, 40 A total
• Wi-Fi 2.4 GHz (802.11 b/g/n) direct connection — no Zigbee/Z-Wave hub needed
• Tuya Smart / Smart Life app for Android and iOS
• Voice control via Amazon Alexa and Google Assistant
• Three control modes: self-locking, interlock, and inching (momentary)
• Wide input: AC 85–250 V or DC 7–32 V
• CE and RoHS certified

In daily use

Wire the screw terminals to garage doors, blinds, solenoid valves, or lighting contactors. In self-locking mode each channel behaves like a standard on/off switch. Interlock mode ensures only one of a pair is active — ideal for motor direction control. Inching mode gives a timed pulse for push-button or momentary devices. The LED status indicator shows Wi-Fi and relay state at a glance, and the module remembers its last state after a power cut.
