12-Channel eWeLink WiFi & 433MHz Relay Controller with Digital Inputs

This 12-channel relay controller brings WiFi app control, a 433MHz handheld remote and wired digital inputs onto one board. It gives equipment builders a way to manage multiple switching circuits from an app or local controls while keeping twelve relay channels together in a compact PCB assembly.

Three ways to control the same installation

The listing specifies eWeLink app access over WiFi, 433MHz RF reception and digital inputs. The illustrated handheld transmitter has twelve numbered buttons for organized channel selection. Wired inputs offer another control path for integration with suitable local switches or external control circuitry.

• eWeLink WiFi app control for a compatible smart device.

• 433MHz wireless reception with a twelve-button remote shown in the gallery.

• Digital-input connectors for wired control integration.

• Twelve relay channels for multi-circuit switching.

Select the switching behavior for the task

The source lists momentary, self-locking and toggle operation. Choose the behavior that matches the equipment: a brief command, a maintained output or a change of state. Confirm the setup method and how the WiFi, RF and digital-input commands interact before commissioning the installation.

DC power with a Type-C connection

The board supports DC 7–24V power through its marked supply terminals. A Type-C connector is also present, with a 5V marking on the illustrated board. These are different power connection points; use the voltage appropriate to the selected input and confirm the supplied board configuration before connection.

Relay outputs for equipment integration

Screw terminals provide access to the relay connections around the board. The illustrated relay components are marked 10A at 250VAC and 28VDC, but component markings do not establish the safe capacity of every assembled installation. Check the board rating, wiring, terminal capacity and load type, and use suitable external contactors for loads with high starting current where required.

Plan the input wiring and enclosure

The source offers green and blue board variants with four cables. Match the cable pinout, input signal type and required control behavior to the supplied version. As an open PCB, the controller needs suitable mounting, enclosure and wiring protection as part of the finished equipment.

• Confirm the number of loads and assign the twelve channels.

• Specify the board variant, remote and input-cable configuration.

• Check the supply voltage and selected power connection.

• Confirm digital-input levels and pinout before connecting external circuitry.

• Test app setup, RF pairing and each input-to-output assignment.

• Check the output state after power loss and network interruption for the intended application.
