## Summary description

Bistable relay FF BIS-411-24V is a single-module DIN-rail switch designed for 24V AC/AD control circuits. Rated for 16A switching, it maintains its output state without continuous coil power, making it suitable for lighting control, impulse switching, and energy-saving automation in residential and industrial installations.

## Long description

Bistable relay FF BIS-411-24V is a single-module DIN-rail switching device designed for control circuits operating at 24 V AC/AD. The relay provides a changeover contact that latches mechanically after activation, so the output state is retained without continuous coil power. With a switching capacity of 16 A, this compact module integrates into standard distribution boards and is intended for applications requiring energy-efficient impulse switching and reliable state retention.
Advantages
The bistable design eliminates the need for continuous coil current to maintain the output state, reducing standby energy consumption. Its single-module width conserves panel space and allows straightforward DIN-rail mounting. The relay is compatible with 24 V AC/AD control signals and supports loads up to 16 A, making it versatile for lighting and automation circuits. The mechanical latching provides stable state retention during power interruptions.
Suitable for
 Lighting control and impulse switching in residential or commercial installations
 Energy-saving automation schemes where reduced standby consumption is required
 Remote or centralized switching in building management systems using 24 V control signals
 Applications that require stable contact state during power loss or after a control pulse
Key specifications
 Nominal control voltage: 24 V AC/AD
 Maximum switching current: 16 A
 Mounting: 1-module on standard DIN-rail
 Contact type: bistable (latching) changeover contact
 Designed for control and switching of resistive and inductive loads in low-voltage circuits
How to use
Install the relay onto a standard DIN-rail and connect the control and load terminals according to the wiring diagram supplied by the manufacturer. Apply a 24 V AC/AD control pulse to change the relay state; the module will mechanically latch in the new position and hold the output without further coil power. To toggle the output again, apply the alternate control pulse. Observe proper polarity and wiring practices for safe installation and ensure the connected load does not exceed the 16 A rating.
Usage recommendations
Use appropriate overcurrent protection and select contactors or external protective devices when switching inductive or capacitive loads. Ensure the installation environment meets the relay's specified temperature and humidity ranges, and follow local electrical regulations and the manufacturer's installation instructions for safe and reliable operation.
