Two-Channel Wi-Fi Dry-Contact Relay Controller

Add app-controlled switching to a compatible circuit with a two-channel Tuya/Smart Life dry-contact relay module.

✅ Switch a circuit from the phone - The Wi-Fi connection brings configured relay control into the Tuya or Smart Life app.

✅ Choose how the relay behaves - Inching, self-locking and interlock modes support different switching tasks.

✅ Schedule the switching action - Per-channel timing lets a configured circuit follow the selected schedule.

✅ Add a compatible handheld control - RF433 support provides another control route after correct pairing.

Choose the switching mode for the circuit

A dry-contact module can provide a control command without supplying voltage to the load itself. That makes it a component for a correctly designed switching or motor-direction circuit.

Verify supply, relay ratings and the complete wiring plan before installation. This module does not control motor speed, includes no actuator and has no USB power port; use the required interlocks and protection for the actual mechanism.
