F&F BIS-408 Bistable Relay 1NO 16A 100-265V AC IP20

The F&F BIS-408 is a reliable bistable impulse relay engineered for the remote control of lighting and various electrical devices. By utilizing a 1NO contact configuration, this device enables the sequential switching of circuits through the use of momentary push-buttons. It is designed to operate efficiently across a broad voltage range of 100-265V AC, ensuring compatibility with diverse electrical installations in both residential and commercial environments.

Advantages

The primary benefit of the F&F BIS-408 is its ability to manage lighting from multiple locations using simple parallel-connected push-buttons, which significantly simplifies wiring compared to traditional cross-switching systems. With a robust 16A switching capacity, it handles standard electrical loads with ease. Its wide input voltage range provides flexibility for various power supply conditions, while the compact design allows for straightforward installation in standard electrical enclosures.

Suitable for

• Remote control of lighting circuits in hallways and staircases
• Automation of electrical devices in residential buildings
• Commercial lighting management systems
• Integration with momentary push-button switches

This relay may not be suitable for applications requiring high-frequency switching or for controlling inductive loads that exceed the specified 16A current rating. It is also not intended for outdoor use or environments with high humidity, as the device carries an IP20 ingress protection rating.

Key specifications

• Contact configuration: 1NO (Normally Open)
• Maximum switching current: 16A
• Operating voltage range: 100-265V AC
• Ingress protection: IP20
• Control method: Momentary push-button

To use the F&F BIS-408, connect the power supply and the load to the designated terminals according to the wiring diagram. Connect one or more momentary push-buttons in parallel to the control input. Each press of a button will toggle the state of the relay, switching the connected load on or off. Ensure all electrical connections are secure and performed by a qualified professional in accordance with local safety regulations.

What to consider before purchase

• Verify that the total load current does not exceed 16A
• Ensure the installation environment is dry and protected from dust
• Confirm that your existing wiring supports the use of momentary push-buttons
• Check that the voltage supply is within the 100-265V AC range

Usage recommendations

For optimal performance and longevity, ensure the relay is installed in a well-ventilated enclosure and avoid exceeding the maximum switching capacity. Regularly inspect connections to maintain electrical integrity.
