The Lutron LMK-16R-DV-B RF Relay Module is a powerful wireless load controller designed to add smart ON/OFF switching capability for heavy-duty lighting and fan loads in residential and commercial automation systems. Utilising Lutron’s Clear Connect RF technology, this module communicates reliably with central controllers like the RA2 Select Main Repeater, RadioRA 2 processors, and HomeWorks automation systems — enabling remote control, scene integration, and automation scheduling.
Unlike standard dimmers that control light intensity, the LMK-16R-DV-B switches mains loads up to 16A, giving electricians and integrators a robust way to handle larger circuits including banks of lights, heaters, and motors (up to 6A on motor loads). Its Softswitch technology helps extend product life by minimising contact arcing and delivering dependable performance over thousands of cycles.
Compact enough to mount inside a junction box yet rugged enough for demanding installations, this module is a go-to component in scalable lighting and automation projects — whether you’re upgrading an existing installation or building a fully integrated smart system from scratch.
How It Works Within the System
The LMK-16R-DV-B relay module functions as a wireless switched output device within Lutron’s ecosystem. Once installed in a junction box and powered from the mains, it receives RF commands over Lutron Clear Connect (~868 MHz for UK/EU markets) from system controllers or repeaters such as the RA2 Select Main Repeater.
Upon receiving a “ON/OFF” instruction, the relay module energises or de-energises its internal contact to switch the connected load — up to 16A of general-purpose lighting or 6A of motor loads — without any hardwired control cabling.
Because it operates wirelessly, the module can be placed where needed and included in scenes, automation schedules, and sensor-based control routines programmed via the Lutron App or professional control software. Its Softswitch contact design reduces wear and tear for long-term reliability.
