F&F BIS-419i 230V Bistable Relay 2P 16A 100-265V AC

The F&F BIS-419i 230V is a high-performance bistable relay engineered for the remote control of lighting systems and electrical devices. By utilizing momentary push-buttons, this impulse relay allows users to toggle circuits on and off from multiple locations, providing a flexible solution for modern electrical installations. Its 2P configuration and 16A contact rating ensure robust performance in both residential and industrial environments, while the wide input voltage range of 100-265V AC guarantees compatibility with various power grids.

Advantages

This bistable relay offers significant convenience by enabling multi-point control of a single load, which is ideal for long corridors or large rooms. The device is designed for reliability and energy efficiency, ensuring that the electrical circuit remains in the desired state without constant power consumption by the relay coil. Its broad voltage tolerance makes it a versatile component that can withstand fluctuations in the power supply, protecting connected equipment and ensuring consistent operation over time.

Suitable for

• Lighting control in residential hallways and staircases
• Industrial automation systems requiring remote switching
• Multi-point control of electrical appliances
• Energy management systems in office buildings

This relay may not be suitable for applications requiring high-frequency switching or for controlling loads that exceed the 16A current rating. It is also not intended for use in environments with extreme moisture or dust without appropriate protective housing.

Key specifications

• Contact configuration: 2P
• Maximum current rating: 16A
• Input voltage range: 100-265V AC
• Control method: Momentary push-buttons

To use the F&F BIS-419i, connect the relay to the power supply and the load according to the wiring diagram. Connect one or more momentary push-buttons in parallel to the control input. Each press of a button will change the state of the relay, switching the connected load on or off. Ensure all connections are secure and performed by a qualified professional in accordance with local electrical regulations.

What to consider before purchase

• Verify that your total load current does not exceed 16A
• Ensure the control buttons are of the momentary (non-latching) type
• Check that the installation space is dry and protected from environmental hazards

Usage recommendations

For optimal performance and longevity, ensure that the relay is installed in a standard electrical distribution board and that the wiring is correctly sized for the 16A load. Periodically inspect the connections to ensure they remain tight and free from oxidation.
