## Summary description

The F&F BIS-411 1R1Z 24V is an electronic impulse relay designed for lighting control and electrical circuit switching. It operates on 24V AC/DC voltage with a maximum load current of 8A. Featuring 1 normally open (NO) and 1 normally closed (NC) contact, this relay allows for convenient remote control of lighting systems from multiple points using momentary push-buttons. Ideal for residential and industrial electrical installations.

## Long description

The F&F BIS-411 1R1Z 24V is an electronic impulse relay engineered for efficient lighting control and electrical circuit switching. This device enables the remote operation of lighting systems from multiple locations through the use of momentary push-buttons, providing a flexible solution for modern electrical installations. Operating on a 24V AC/DC power supply, it ensures reliable performance in both residential and industrial environments.
Advantages
The primary benefit of this impulse relay is its ability to simplify complex wiring by allowing a single lighting circuit to be controlled from an unlimited number of points using simple parallel-connected buttons. The inclusion of both a normally open and a normally closed contact provides versatility in circuit design, allowing for various switching configurations. Its electronic design ensures quiet operation and long service life compared to traditional mechanical relays, making it an ideal choice for areas where noise reduction is required.
Suitable for
Residential lighting control systems
Industrial automation and circuit switching
Multi-point lighting control in hallways and staircases
Integration with low-voltage control systems
When it may not be suitable
This relay is not designed for high-power applications exceeding the 8A load limit, so it should not be used for heavy-duty motors or high-wattage industrial heating elements. Additionally, it requires a 24V AC/DC power source and cannot be connected directly to standard 230V mains voltage without appropriate transformation.
Key specifications
Supply voltage: 24V AC/DC
Maximum load current: 8A
Contact configuration: 1 NO (normally open) and 1 NC (normally closed)
Control type: Momentary push-button
Mounting: Standard electrical installation
How to use
The relay is installed within an electrical distribution board or junction box. Connect the 24V power supply to the designated input terminals. The control circuit is wired using momentary push-buttons connected in parallel to the control input of the relay. Each time a button is pressed, the relay toggles the state of the output contacts, switching the connected load on or off. Ensure that all wiring is performed by a qualified professional in accordance with local electrical safety regulations.
What to consider before purchase
Verify that your control circuit operates on 24V AC/DC
Ensure the total load current of your lighting circuit does not exceed 8A
Check available space in your electrical enclosure for mounting
Confirm the compatibility of your push-buttons for momentary operation
Usage recommendations
For optimal longevity and safety, ensure that the relay is protected against voltage surges and that the load connected to the contacts does not exceed the specified current rating. Regularly inspect connections to ensure they remain tight and free from oxidation.
