## Summary description

Bistable (latching) relay FF BIS-411i 24V designed for on/off switching in control and automation circuits. Operates from a 24 V supply and maintains contact state without continuous coil power. Suitable for DIN-rail mounting in switchboards, for energy-saving switching, memory functions, and remote control of lighting, motors, or other loads where retained state is required.

## Long description

The FF BIS-411i 24V bistable (latching) relay is designed for reliable on/off switching in control and automation installations. It operates from a 24 V DC supply and holds its contact position after the drive signal is removed, eliminating the need for continuous coil current. The housing is compatible with standard DIN-rail mounting, making the unit suitable for installation in electrical distribution boards and control cabinets where retained state and low standby consumption are required.
Advantages
The latching mechanism maintains the relay state without constant power to the coil, reducing energy consumption and heat generation in the panel. Compact DIN-rail compatible design allows neat integration in switchboards and simplifies wiring. The relay provides a stable mechanical contact for on/off control of lighting, small motors, actuators and other loads where memorized state or remote switching is needed.
Suitable for
Remote on/off control of lighting circuits
Memory functions in automation and control systems
Switching small motors and actuators with retained state
Energy-saving installations where coil power must be minimized
DIN-rail mounted switchboards in residential, commercial, or industrial environments
Key specifications
Operating voltage: 24 V DC
Type: bistable (latching) on/off relay
Mounting: DIN-rail compatible enclosure
Contact function: maintained contact state after pulse
Typical applications: control and automation circuits, lighting and motor control
How to use
Install the relay on a standard DIN rail inside an appropriate distribution or control enclosure and connect the control pulses to the designated coil terminals following the wiring diagram supplied with the unit. Apply a short set pulse to change the relay to the ON state and a reset pulse to return it to OFF; the contacts will remain in their last position without continuous coil power. Verify correct polarity and secure terminal connections before energizing the control circuit. Observe the device’s rated voltage and ensure load ratings are compatible with the relay contacts.
Usage recommendations
Use the bistable relay in applications where maintaining contact state without continuous power is important. Provide surge protection and proper overload protection for connected loads, and follow applicable installation standards when mounting in switchboards. Test switching sequences during commissioning to confirm correct operation with your control system.
