## Summary description

OXT T210DC is a mini volt-free relay module with Wi‑Fi (Tuya) integration. It provides a dry contact switching output compatible with AC 230V loads and accepts DC control voltages of 5V or 12–48V as specified. Designed for remote switching and home automation, it suits lighting, boiler, gate or alarm control where isolated relay contact and smart Wi‑Fi control are required.

## Long description

OXT T210DC is a compact volt-free contact relay module with built-in Wi‑Fi (Tuya) control. The module provides an isolated dry contact output suitable for switching AC 230V loads while accepting DC control voltages of 5V or a selectable 12–48V range. Designed for integration into smart home and automation systems, this mini relay enables remote switching of circuits that require an isolated contact and supports Tuya-based cloud and local control ecosystems.
Advantages
The module combines a physically isolated volt-free contact with Wi‑Fi connectivity, allowing safe switching of mains AC loads without electrical connection between the control input and the switched circuit. Its small footprint makes it suitable for tight installation spaces. Support for both 5V and 12–48V DC control voltages provides flexible integration with different control systems and power supplies. Tuya compatibility enables pairing with common smart home apps and voice assistants for remote control and scheduling.
Suitable for
 Remote switching of lighting circuits that require an isolated contact
 Control of boilers or heating systems with a volt-free thermostat input
 Integration with gate or garage door controls that use dry contacts
 Alarm and security systems needing an isolated relay interface
Key specifications
 Output type: volt-free (dry) contact relay for switching AC loads
 Switched supply compatibility: AC 230V loads
 Control input voltage: DC 5V or DC 12–48V (selectable/control-accepted range)
 Connectivity: Wi‑Fi with Tuya platform support for cloud and local control
 Form factor: mini relay module suitable for compact installations
How to use
Install the OXT T210DC in a suitable enclosure or DIN-rail sub-module space following local electrical regulations. Connect the switched circuit to the relay's volt-free contact terminals so that the AC 230V load is isolated from the control input. Apply the appropriate DC control voltage to the control input (either 5V or within 12–48V as required by your installation). Configure Wi‑Fi credentials and Tuya integration using the manufacturer’s pairing procedure to enable remote control, scheduling, and automation via the Tuya-compatible app or a connected smart home hub.
Usage recommendations
Verify compatibility with the controlled device by checking that it accepts a volt-free contact and that the AC mains load does not exceed the relay’s rated switching capacity. Follow safety practices: power down circuits before wiring, use appropriate fuses or protective devices, and enclose the module to prevent accidental contact. For integration with professional control systems or systems requiring fail-safe behavior, consult an electrician or system integrator.
