Projecta IQMR4 Smart Relay – 4 Channel LIN Bus Intelligent Control

The Projecta IQMR4 Smart Relay is a multi-channel, LIN bus-compatible relay module, purpose-built for advanced 12V power automation in automotive, caravan, 4WD, and marine setups. Designed as part of the Projecta Intelli-IQ ecosystem, the IQMR4 enables intelligent control of up to four separate accessories or circuits, each with independent switching and advanced scheduling via the Projecta IQ App or IQD2 smart display.

Please note:
The IQMR4 requires a Projecta Intelli-IQ Controller - such as the IQD2 - to function. All configuration, operation, and monitoring is managed through the IQD2 or compatible Intelli-IQ controller, using either the display or the Projecta IQ App.

With a maximum output of 10A per channel (30A total), the IQMR4 allows for flexible configuration, supporting custom schedules, delay-off timers, advanced lighting control (including brightness and flash patterns), and linked/conditional switching. It’s the ideal solution for anyone looking to add smart automation, energy management, or scene control to modern vehicles and installations.
