## Long description

The F&F BIS-412iM is a professional 1-pole bistable relay engineered for the efficient group control of lighting systems and various electrical circuits. Operating at 230V AC with a robust 16A contact rating, this device provides a reliable solution for managing electrical installations in both residential and commercial environments. It features an integrated memory function that ensures the relay retains its last switching state even after a power failure, alongside high resistance to inrush currents of up to 160A/20ms, which is essential for modern LED lighting applications.
Advantages
The primary benefit of the BIS-412iM is its ability to handle high inrush currents, preventing contact welding when switching capacitive loads like LED drivers. The group control functionality allows for the simultaneous management of multiple circuits from a single point, simplifying complex lighting setups. Furthermore, the memory function provides consistent operation by automatically restoring the previous state upon power restoration, eliminating the need for manual resetting. Its compact design ensures easy installation within standard electrical distribution boards.
Suitable for
Group control of lighting circuits in residential buildings
Managing electrical installations in commercial offices
Switching LED lighting systems with high inrush currents
Remote control of electrical loads via momentary push-buttons
When it may not be suitable
This relay is designed for AC voltage systems and is not compatible with DC circuits. It may not be suitable for applications requiring high-frequency switching or for loads exceeding the specified 16A current rating.
Key specifications
Contact configuration: 1-pole (1P)
Rated current: 16A
Supply voltage: 230V AC
Inrush current resistance: 160A/20ms
Function: Bistable with memory
How to use
The relay is designed for mounting on a standard DIN rail within an electrical distribution cabinet. It is controlled by momentary push-buttons connected to the control input. Each press of the button toggles the relay state between on and off. For group control, multiple relays can be linked to the same control signal, allowing a single button to switch all connected circuits simultaneously. Ensure all wiring is performed by a qualified electrician in accordance with local safety regulations.
What to consider before purchase
Verify that the total load of the connected circuits does not exceed 16A
Ensure the control system uses momentary push-buttons
Confirm the installation space is suitable for DIN rail mounting
Check compatibility with the specific type of lighting or load being controlled
Usage recommendations
For optimal performance and longevity, ensure that the relay is installed in a well-ventilated enclosure and that all terminal connections are tightened to the manufacturer's specified torque.
