## Summary description

The F&F BIS-411-1R1Z is a bistable relay designed for impulse-based lighting control. It allows for switching electrical circuits on and off from multiple locations using momentary push-buttons. This reliable electromechanical device is ideal for residential and commercial automation systems, ensuring efficient control of lighting fixtures and other electrical loads through a simple pulse signal.

## Long description

The F&F BIS-411-1R1Z bistable relay is a high-quality electromechanical device engineered for impulse-based lighting control. It enables the convenient switching of electrical circuits on and off from several different locations by utilizing simple momentary push-buttons. This relay is a robust solution for modern residential and commercial automation systems, providing reliable performance for managing lighting fixtures and various electrical loads through a single pulse signal.
Advantages
This bistable relay offers a significant improvement in electrical installation flexibility by allowing control from an unlimited number of points. Its electromechanical design ensures long-term durability and consistent operation under standard electrical loads. The device is designed for easy integration into existing electrical panels, making it an efficient choice for both new construction projects and renovation tasks where multi-point control is required.
Suitable for
Controlling lighting in long hallways or staircases from multiple switches
Managing electrical loads in residential smart home setups
Commercial office lighting automation
Industrial control panels requiring impulse-based switching
When it may not be suitable
This device is not intended for high-power industrial motors or loads that exceed the specified contact current capacity. It is also not suitable for applications requiring dimming functionality or complex programmable logic beyond simple on-off switching.
Key specifications
Control voltage: 230V AC
Contact configuration: 1 NO/NC (normally open/normally closed)
Mounting type: DIN rail (35mm)
Maximum load current: 16A
Operating temperature range: -25°C to +50°C
How to use
The relay is installed on a standard 35mm DIN rail within an electrical distribution board. Connect the phase and neutral wires to the power terminals and link the momentary push-buttons in parallel to the control input. Each time a pulse is sent from any connected push-button, the relay changes its state, toggling the connected load between the on and off positions.
What to consider before purchase
Ensure the total power of the connected lighting load does not exceed the relay's maximum current rating
Verify that the control circuit voltage matches the relay specifications
Confirm that the installation space allows for DIN rail mounting
Usage recommendations: For optimal performance and safety, ensure all electrical connections are tightened securely and that the circuit is protected by an appropriate miniature circuit breaker. Avoid installing the device in environments with excessive humidity or extreme temperatures.
