Product information

Description

The F&F BIS-411B is a high-quality bistable relay engineered for the efficient control of lighting and electrical circuits. This device allows for the switching of electrical loads through impulse signals sent from momentary push-buttons. A standout feature of this model is the integrated manual control button located directly on the housing, which provides the flexibility to toggle the circuit state locally without needing external inputs. Designed for installation on a standard 35 mm DIN rail, it integrates seamlessly into modern electrical distribution boards for both residential and industrial automation applications.

Advantages

The primary benefit of the F&F BIS-411B is its versatility in managing electrical loads from multiple locations using simple parallel-connected push-buttons. The inclusion of a manual override button ensures that the system remains operational even if the control circuit experiences issues or if immediate local intervention is required. Its robust construction and DIN rail mounting compatibility make it a reliable choice for professional electrical installations, ensuring long-term performance and ease of maintenance within complex wiring systems.

Suitable for

Controlling lighting systems from multiple points in hallways or staircases
Managing electrical appliances via impulse signals
Industrial automation and control panel integration
Smart home lighting setups requiring manual override capabilities

When it may not be suitable

This relay is not designed for high-power industrial motors or loads that exceed its rated switching capacity, as this could lead to premature contact failure. It is also not intended for applications requiring complex logic or programmable timing functions, as it operates strictly as a simple bistable switching device.

Key specifications

Mounting type: 35 mm DIN rail
Control method: Impulse signal via push-buttons or integrated manual button
Operating voltage: Standard electrical grid compatibility
Design: Bistable relay mechanism

How to use

To install the device, mount it onto a standard 35 mm DIN rail within your electrical cabinet. Connect the power supply and the load according to the wiring diagram provided with the unit. Connect the external momentary push-buttons in parallel to the control input terminals. Once powered, a short impulse from any connected button will toggle the relay state. You can also press the manual button on the front of the device at any time to switch the load on or off independently of the remote control inputs.

What to consider before purchase

Ensure the electrical load does not exceed the relay's maximum switching current
Verify that your control wiring supports momentary impulse signals
Confirm available space on the DIN rail within your distribution board

Usage recommendations

For optimal longevity and safety, ensure that all electrical connections are tightened securely and that the device is installed in an environment protected from excessive moisture, dust, and extreme temperatures.
