The Control4 DIN-Rail 8-Channel Relay Switch controls up to eight high in-rush loads from one module in the
Control4 system. Each channel supports a variety of load types, including incandescent, halogen, electronic low-voltage transformers, magnetic low-voltage transformers, fluorescents, compact fluorescents, LEDs, and motors.



• Controls up to eight high in-rush loads
• Channel buttons allow for toggling a load on/off
• Channel status LEDs indicate whether a load is on or off
• Module Override button allows toggling between the module override scene and all channels off or
setting the module override scene to to the current channel’s on/off settings
• Module Status LED indicates if module power is on with normal operation, off, or in thermal overload
• Link/Activity LED indicates system link status, communication activity, or firmware update status
• Reset button can be used for restoring factory defaults or network configuration settings
• Auxiliary override connection allows a standard line-voltage toggle switch to control the attached lights
before the control system is installed or in case the controller malfunctions
• Module can be installed in either a Contro4 5- or into a 2-slot panel or into a third-party DIN rail panel
