## Summary description

The F&F BIS-412 24V is a group impulse relay designed for lighting control systems. It operates on 24VAC/DC with a maximum load current of 16A. This device is intended for mounting on a standard TH35 DIN rail, providing reliable switching functionality for electrical circuits. It is ideal for industrial and residential automation, allowing for efficient control of lighting groups from multiple locations.

## Long description

The F&F BIS-412 24V is a group impulse relay engineered for efficient lighting control in both residential and industrial electrical systems. Operating on a 24VAC/DC supply, this device enables the switching of lighting circuits from multiple locations using momentary push-buttons. Its robust design ensures reliable performance in demanding environments, making it a versatile component for modern automation setups.
Advantages
This impulse relay offers a significant advantage by allowing the control of lighting groups from several independent points, which enhances convenience and energy management. The device is built for seamless integration into standard electrical cabinets, featuring a compact design that mounts directly onto a TH35 DIN rail. Its high load capacity of 16A ensures compatibility with various lighting types, while the 24V operating voltage provides an added layer of safety for control circuits.
Suitable for
Residential lighting control systems with multiple switches
Industrial automation and facility management
Public building lighting management
Integration into smart home or building automation panels
When it may not be suitable
This device is not intended for use in high-voltage control circuits exceeding its specified 24V rating. It is also not suitable for applications requiring dimming functionality or complex programmable logic, as it operates strictly as a bistable switching relay.
Key specifications
Supply voltage: 24V AC/DC
Maximum load current: 16A
Mounting type: TH35 DIN rail
Control method: Momentary push-buttons
Function: Group impulse switching
How to use
The relay is installed by snapping it onto a standard TH35 DIN rail within an electrical distribution board. Connect the 24V power supply to the designated terminals and wire the momentary push-buttons in parallel to the control input. Once energized, each press of a connected push-button toggles the state of the relay, switching the connected lighting load on or off.
What to consider before purchase
Ensure your control circuit voltage matches the 24V specification
Verify that the total load current of the lighting group does not exceed 16A
Confirm that you have sufficient space on your DIN rail for installation
Check that your wiring setup supports momentary push-button configuration
Usage recommendations
For optimal longevity and safety, ensure all electrical connections are tightened securely and the device is protected from moisture and extreme temperatures within a suitable enclosure.
