Self-Locking Interlock Remote Control 1 Way Relay Module with 7-32V WiFi

This relay module delivers straightforward remote switching for home automation and industrial control applications. It operates over a wide voltage range, from 7V to 32V DC, making it compatible with many power supplies. The self-locking interlock feature ensures that a single command toggles the relay state, simplifying control of lights, pumps, or other appliances. With a 2.4G WiFi interface and USB communication, it integrates easily into existing networks and can be managed via the Ewelink app.

Features and Construction

Built for reliable wireless control, this module uses a PCB onboard antenna and WiFi to communicate. Its compact enclosure keeps installation simple in junction boxes or behind panels.

Material and Build

The module uses a solid-state or electromechanical relay rated for the specified voltage range. The body is housed in a plastic casing with dimensions 15cm x 8cm x 2cm, weighing just 0.1kg. All connections are via screw terminals, and the PCB antenna is integrated for consistent signal strength.

Size and Practical Fit

Measuring 15 by 8 by 2 centimetres, this unit fits into standard electrical enclosures. Its lightweight design means it can be mounted with adhesive or screws without strain. The USB interface provides an alternative wired programming or control path.

Uses and Placement

This relay is suited for both home and light commercial settings where one-way remote switching is needed. The self-locking interlock prevents accidental double-trigger issues.

Event or Professional Use

In professional environments, it can control lighting or automation sequences. The wide voltage tolerance allows connection to 12V or 24V systems common in alarms, gates, and industrial panels.

Everyday Home Use

For home users, it works well for turning lamps, fans, or small appliances on or off remotely via smartphone. The Ewelink compatibility gives straightforward scheduling and status feedback.

Benefits and Buying Value

This module offers a cost-effective way to add wireless control to existing equipment. Its low weight and compact size simplify installation, while the self-locking interlock reduces the chance of unintended on/off cycles.

Reuse and Low Maintenance

The relay requires no routine maintenance beyond keeping the enclosure dust-free. Its solid-state design means no moving parts to wear out in normal use. The unit can be repurposed for different projects with ease by reprogramming via USB or app.

Why Choose This Product

If you need a straightforward, single-channel relay with wide voltage support and WiFi control, this module is a practical choice. It provides reliable communication over 2.4G networks and can be operated from anywhere through the Ewelink app. The PCB antenna ensures stable connectivity without external aerials.
