Tuya Four-Channel Wi-Fi Relay Module

Control several compatible circuits from one smart-switch module. These four-channel Tuya relay selections offer app control and configurable switching modes, with a separate remote-only option.

✅ Manage several outputs in one project - The four-channel module brings separate control points into one installation.

✅ Choose how a relay responds - Inching and self-locking modes support momentary or retained switching in a matched application.

✅ Use app or matched RF control - The module supports Smart Life/Tuya and the specified 433MHz learning-code remotes.

Choose the Control Behaviour for the Task

A momentary command and a maintained on/off state serve different jobs. Select the mode for the controlled equipment and test its response before completing the installation, including what happens after a power interruption.

Choose the supply-voltage version and whether you need the shell. The 4CH Remote option is the handset only. Relay contacts do not provide a new output supply; voltage, load type and wiring must match the installation. A remote is separate from module packages.
