Dependable switching within your system

Relays switch non-dimmable and higher-load circuits within a control system. We help select relays rated for the load, including higher inrush, for reliable switching.

Common Applications

  • Non-dimmable lighting
  • Higher-load circuits
  • Integration with control systems
  • Mixed switching and dimming

Common questions

  • When do I need a relay?

    You need a relay to switch non-dimmable lighting or higher-load circuits on and off within a control system, including loads with higher inrush. Relays let switched circuits be controlled alongside dimmed lighting. The right relay depends on the load characteristics. Share the load details and we can help specify a suitable relay for reliable switching.

  • Can relays handle higher-inrush loads?

    Yes. Relays are designed for reliable switching, including circuits with higher inrush current. Selecting a relay rated for the load and its inrush characteristics is essential for dependable operation and long life. Share the load type and characteristics and we can help specify a suitable relay that handles the switching demands of your circuit.

  • Can I control switched and dimmed lighting from one system?

    Yes. Relays switch non-dimmable and higher-load circuits while dimmers control dimmable loads, all within the same control system. This lets varied lighting be managed together. We help select compatible relays and dimmers so switching and dimming coordinate reliably. Share your loads and control objectives and we can advise on a suitable combination.

Selecting control relays

Relays provide on/off switching of electrical loads within a control system, controlling non-dimmable lighting and higher-load circuits, including loads with higher inrush. They let switched circuits be managed alongside dimmed lighting. The right relay depends on the load characteristics and switching demands. Correct specification supports reliable operation and long service life.

Need help selecting a relay?

Relay selection depends on the load type, its inrush characteristics and how it integrates with the control system. Share these details and we can help specify a suitable relay for dependable switching, subject to confirming the load.

Frequently asked questions

  • What information do you need to recommend a relay?

    The most useful details are the load type, the load rating and its inrush characteristics, and how the circuit integrates with the control system. With this we can help specify a relay rated for the load, so switching is reliable and the device is correctly matched. Sharing the load details helps us flag anything that needs checking.

  • Why does inrush current matter for relay selection?

    Some loads draw a high inrush current when switched on, which can stress an underrated relay and shorten its life or cause unreliable switching. Selecting a relay rated for the load and its inrush avoids this. Share the load characteristics and we can help specify a relay designed to handle the switching demands reliably.

  • Can relays be controlled from the same system as dimmers?

    Yes. Relays and dimmers both operate within the control system, so switched and dimmed lighting can be coordinated together. We help select compatible relays and dimmers so the system behaves consistently. Sharing your loads and control objectives lets us recommend a suitable combination for reliable mixed control.

  • Do you provide product data for relays?

    Yes. We can provide datasheets and technical documentation to support relay selection. Tell us the load and system and we can supply the relevant data or help specify a suitable relay from the load characteristics, supporting reliable switching and correct integration with the control system.

  • Can you supply relays alongside the rest of the system?

    Yes. We supply relays alongside dimmers, power supplies, couplers, interfaces and Tridonic components, so you can source a complete control system from one place. We help ensure the relay is rated for the load and integrates with the system, supporting dependable switching across the installation.
