WiFi switch Avatto WSM16-DC-1 1-channel dry contact DC

Avatto WSM16-DC-1 is a compact WiFi switch providing a single dry contact output designed for DC circuits. It enables remote on/off control of external DC-powered devices over a wireless network and can be integrated into home automation systems. The module supports straightforward installation and offers an interface for controlling lighting, pumps, relays or other low-voltage equipment that require a dry contact input.

Advantages

The device offers a single-channel dry contact output that isolates the switching circuit from the module's power and WiFi electronics, reducing interference risks when controlling external DC equipment. Its WiFi connectivity allows remote control and scheduling via compatible apps or automation hubs, enabling centralized management of devices. The compact form factor and simple wiring make it suitable for retrofit projects and installations with limited space. The design focuses on reliable switching for low-voltage DC loads and compatibility with common smart home setups.

Suitable for

• Remote on/off control of DC-powered lighting
• Switching low-voltage pumps or fans with dry contact input
• Integration with smart home systems and automation scenes
• Triggering relays or controllers that accept a dry contact closure
• Retrofit installations where isolation between control and load is required

Key specifications

• Single dry contact output for DC circuits
• WiFi wireless connectivity for remote control
• Compact module suitable for installation in enclosures or behind devices
• Designed for controlling low-voltage DC equipment via isolated contact
• Compatible with common smart home control methods and scheduling

How to use

Install the Avatto WSM16-DC-1 according to local electrical codes, mounting it in a suitable enclosure or location near the device to be controlled. Connect the module's dry contact terminals in series with the controlled device's DC control input or relay coil; supply power to the module according to the manufacturer's wiring instructions. Use the compatible mobile app or a supported automation hub to connect the switch to the local WiFi network, configure the device, and assign on/off controls or schedules. Test the switching function after installation to confirm correct operation and isolation.

Recommendations

Use the switch only with devices and control circuits that accept a dry contact input and operate within the safe voltage and current limits of the controlled equipment. Ensure proper enclosure and strain relief for wiring, keep the module away from moisture and excessive heat, and follow applicable safety standards and local regulations during installation and maintenance.
