## Summary description

The FF BIS-411 2Z 24V is an impulse relay designed for remote lighting or device control. It features an 8A contact rating and operates on 24V AC/DC voltage. Equipped with two normally open (2NO) contacts, this bistable relay allows for switching electrical circuits via momentary push-buttons, making it an efficient solution for residential and industrial automation systems requiring reliable pulse-based switching.

## Long description

The FF BIS-411 2Z 24V is a bistable impulse relay engineered for the remote control of lighting systems and various electrical devices. This device enables the switching of electrical circuits through the use of momentary push-buttons, providing a flexible and reliable solution for managing electrical loads in both residential and industrial environments. Operating on a 24V AC/DC supply, it ensures consistent performance in automation setups requiring pulse-based control.
Advantages
The primary benefit of this impulse relay is its ability to control a single lighting circuit or device from multiple locations using simple parallel-connected momentary switches. Its bistable design means the relay maintains its state after a pulse, which significantly reduces energy consumption compared to traditional contactors that require constant coil power. The inclusion of two normally open contacts provides versatility for managing complex circuit configurations, while the compact design allows for easy installation in standard electrical distribution boards.
Suitable for
Remote lighting control from multiple points
Automation of electrical devices in residential buildings
Industrial control systems requiring pulse-based switching
Integration with building management systems
This relay may not be suitable for applications requiring high-current switching beyond its 8A rating or for systems that demand continuous, non-pulse-based latching logic. 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 operation.
Key specifications
Supply voltage: 24V AC/DC
Contact configuration: 2 x Normally Open (2NO)
Maximum load current: 8A
Control type: Impulse (bistable)
Mounting: Standard electrical distribution rail
How to use
The relay is installed in an electrical distribution cabinet on a standard mounting rail. Connect the 24V power supply to the designated terminals and wire the momentary push-buttons in parallel to the control input. Each press of a push-button sends a pulse to the relay, which toggles the state of the two normally open contacts, thereby switching the connected load on or off. Ensure that the total load current does not exceed the 8A limit to prevent damage to the internal contacts.
What to consider before purchase
Verify that your control system operates on 24V AC/DC
Ensure the total load current of your devices is within the 8A limit
Check available space in your distribution board for installation
Confirm that your wiring supports the use of momentary push-buttons
Usage recommendations: Always ensure that the power supply is disconnected before performing any wiring or maintenance. It is recommended to use a qualified electrician for installation to ensure compliance with local electrical safety standards and to prevent potential damage to the relay or connected equipment.
