F&F BIS-414 24V Impulse Relay 24V AC/DC 2x10A for TH35 Rail

The F&F BIS-414 24V is a high-quality bistable impulse relay engineered for reliable control of lighting and electrical devices. Designed for seamless integration into electrical cabinets, this unit mounts directly onto a standard TH35 rail. It operates on a 24V AC/DC power supply and is equipped with two independent 10A contacts, providing a robust solution for managing circuits from multiple remote locations using simple momentary push-buttons.

Advantages

This impulse relay offers significant flexibility in electrical design by allowing users to switch loads from various points in a building, which is ideal for long corridors or large rooms. The bistable mechanism ensures that the relay maintains its state even after the control signal is removed, consuming power only during the switching moment. Its compact design for TH35 rail mounting saves valuable space in distribution boards, while the dual-contact configuration allows for versatile circuit management in both residential and industrial environments.

Suitable for

• Lighting control in hallways and staircases
• Managing electrical appliances from multiple push-buttons
• Industrial automation systems requiring bistable switching
• Modernizing electrical installations for improved user convenience

This relay may not be suitable for applications requiring high-frequency switching or loads exceeding the 10A current rating per contact. It is also not intended for use in high-voltage AC mains circuits without appropriate voltage conversion, as it is specifically designed for 24V AC/DC systems.

Key specifications

• Operating voltage: 24V AC/DC
• Contact configuration: 2 x 10A
• Mounting type: TH35 rail
• Control method: Momentary push-buttons

To use the F&F BIS-414 24V, mount the device onto a standard TH35 rail within your electrical distribution box. Connect the 24V power supply to the designated terminals and wire your momentary push-buttons in parallel to the control input. Ensure that the load circuits are connected to the relay contacts according to the wiring diagram provided with the device. Once installed, a single press of any connected push-button will toggle the relay state, turning the connected load on or off.

What to consider before purchase

• Verify that your control system operates on 24V AC/DC
• Ensure the total load current does not exceed 10A per contact
• Confirm availability of space on your TH35 rail
• Check that your wiring supports parallel push-button configuration

Usage recommendations

Always ensure that the power supply is disconnected before performing any installation or maintenance work on the electrical circuit. It is recommended to have the installation performed by a qualified electrician to ensure compliance with local safety standards.
