Wireless RF 433 MHz Dual Relay Module ART SH-MORF-2, 2-channel remote relay switch

The ART SH-MORF-2 Wireless RF 433 MHz Dual Relay Module is a compact two-channel remote relay switch that operates on 433 MHz radio frequency. It provides two independent relay outputs for remote control of low-voltage loads and is compatible with standard 433 MHz transmitters. The module is designed for installation in residential and small commercial settings where remote switching of lighting, gates, shutters or similar devices is required. Its compact form factor allows placement inside junction boxes or equipment enclosures for discreet integration into home automation and security systems.

Advantages

The module delivers two independent channels allowing separate control of two circuits from a single RF transmitter. Operating at 433 MHz ensures compatibility with a wide range of standard remotes and existing RF infrastructure. Its compact design supports hidden installation and minimizes space requirements. The relay outputs are suited for switching low-voltage loads reliably, while the simple radio pairing process facilitates quick setup without complex wiring changes.

Suitable for

• Remote control of indoor and outdoor lighting circuits
• Switching electric gate or garage door control inputs
• Operating roller shutters, blinds or awnings
• Integration into basic home automation and security setups

Key specifications

• Radio frequency: 433 MHz
• Two independent relay channels
• Designed for switching low-voltage loads
• Compact module suitable for installation in junction boxes or enclosures
• Compatible with standard 433 MHz remote controls

How to use

Install the module in a dry, ventilated location inside a junction box or enclosure close to the devices to be switched. Connect supply power and the load circuits following the electrical diagram provided with the product, observing polarity and safety guidelines. Pair the module with a compatible 433 MHz transmitter using the manufacturer’s pairing procedure to assign remote buttons to each relay channel. After pairing, test each channel by operating the transmitter to confirm correct switching of the connected loads.

Usage recommendations

For reliable operation, place the module within the recommended range of the 433 MHz transmitter and avoid mounting near large metal masses or sources of RF interference. Verify that connected loads are within the relay’s rated capacity and use proper protective devices where required. For permanent installations, secure wiring connections and enclose the module in a suitable IP-rated box if exposed to moisture.
