Tuya Universal Smart WiFi Relay Module (AC/DC 7–32V Input | Potential-Free Dry Contact Output)

Isolated Dry-Contact Output | Multi-Mode Operation | 240VAC & DC Switching | Tuya & Smart Life Integration

The Tuya Universal Smart WiFi Relay Module is a compact, commercial-grade control solution engineered to integrate smart functionality into standard electrical systems. Featuring complete galvanic isolation between its control circuitry and switching outputs, this module allows low-voltage DC input power to safely switch high-voltage loads up to 240VAC or independent DC circuits. Designed for straightforward deployment, the module connects directly to 2.4GHz Wi-Fi networks and integrates natively with the Tuya Smart and Smart Life ecosystems without requiring a dedicated hub.

Isolated Switching Capability — Safe, Flexible Control

When managing automated systems, safety and galvanic isolation are critical:

• Total Galvanic Isolation: Safely control high-voltage 240VAC mains power using a low-voltage (5V USB or 7–32V DC) power source without risk to control electronics.
• Potential-Free Dry Contacts: The output terminals operate as true potential-free contacts (COM, NO, NC), enabling safe switching of up to 240VAC/10A mains loads directly from a low-voltage power supply.

Advanced Multi-Mode Operation

The relay module adapts to your exact control requirements through three distinct operating modes:

• Self-Locking (Toggle Mode): Standard state switching for continuous power control (lighting, pumps, heating elements).
• Inching Mode (Momentary Pulse): Configurable pulse duration (0.5s to custom intervals) for gate operators, garage door trigger terminals, and electronic strike locks.
• Interlock Mode: Hardware/software interlocking for multi-channel variants to ensure mutually exclusive operation for bidirectional motors.

Ecosystem Integration & Automation Engine

Take full control of your automated environment with seamless smart connectivity:

• Tuya & Smart Life Ecosystems: Fully compatible with Tuya Smart and Smart Life applications on iOS and Android.
• Voice Control: Supports direct voice integration with Amazon Alexa and Google Assistant platforms for hands-free switching.
• Automation & Schedulers: Configure schedules, countdown timers, and automated multi-device scenes effortlessly via the app interface.
