## Summary description

The FF BIS-411BM-LED is a bistable relay designed for DIN rail mounting, featuring a built-in manual control button. It operates at 230V and is engineered to handle high inrush currents of up to 160A for 20ms, making it ideal for controlling LED lighting circuits. This relay provides reliable switching functionality for residential and industrial electrical installations, ensuring efficient load management and long-term durability.

## Long description

The FF BIS-411BM-LED is a professional bistable relay designed for efficient lighting control in residential and industrial electrical systems. Engineered for DIN rail mounting, this device allows for the remote switching of electrical circuits using momentary push-buttons, while also featuring an integrated manual control button directly on the housing for local operation. It is specifically optimized to handle the high inrush currents typical of modern LED lighting, ensuring reliable performance and extended service life.
Advantages
The primary advantage of this bistable relay is its robust design capable of managing high inrush currents of up to 160A for 20ms, which prevents contact welding when switching LED drivers. The inclusion of a manual control button provides added flexibility, allowing users to override the system locally during maintenance or in the event of a control signal failure. Its compact DIN rail form factor ensures seamless integration into standard distribution boards, while the bistable mechanism ensures that the relay maintains its state without continuous power consumption, contributing to energy efficiency.
Suitable for
Controlling LED lighting circuits in homes and offices
Managing lighting in long corridors or staircases with multiple control points
Industrial automation systems requiring reliable pulse-based switching
Retrofitting existing installations to support high-current LED loads
When it may not be suitable
This relay is not intended for use in circuits exceeding its rated voltage or current capacity. It is also not suitable for applications requiring dimming functionality, as it acts strictly as an on-off switch.
Key specifications
Supply voltage: 230V AC
Maximum inrush current: 160A (20ms)
Mounting type: DIN rail (TH-35)
Control: Remote pulse or integrated manual button
Application: LED lighting and resistive loads
How to use
The device should be installed by a qualified electrician onto a standard TH-35 DIN rail within an electrical distribution board. Connect the power supply to the designated terminals and wire the control push-buttons in parallel to the control input. Once installed, the relay will toggle its output state each time a pulse is received from a connected button. The manual button on the front panel can be used at any time to toggle the relay state independently of the remote control circuit.
What to consider before purchase
Ensure the total load of your lighting circuit does not exceed the relay's rated capacity
Verify that your electrical panel has sufficient space on the DIN rail
Confirm that your control wiring supports momentary push-button switches
Usage recommendations
Always ensure the power is disconnected before performing any installation or maintenance work on the electrical circuit. Periodically check the terminal connections to ensure they remain tight and free from oxidation.
