F&F AS-B24 Staircase Timer, 24V, 16A, DIN Rail Mount, 2 Modules, IP40

The F&F AS-B24 is a professional-grade staircase timer engineered for 24V electrical systems, providing precise lighting control in various environments. Designed for efficiency and durability, this device manages lighting circuits with a 16A switching capacity, ensuring reliable operation for both residential and commercial stairwells. Its compact design allows for seamless integration into electrical cabinets, occupying only two modules on a standard DIN rail.

Advantages

This staircase timer offers significant energy savings by automatically deactivating lighting after a pre-configured time interval, which prevents unnecessary power consumption. The robust construction ensures long-term performance, while the 24V compatibility makes it an ideal choice for low-voltage lighting installations. Its DIN rail mounting system simplifies the installation process for electricians, and the IP40 protection rating provides a secure housing against solid objects, contributing to a safe and organized electrical infrastructure.

Suitable for

• Residential stairwell lighting control
• Commercial building corridor illumination
• Low-voltage lighting systems in public facilities
• Automated lighting management in multi-story buildings

When it may not be suitable

This device is specifically designed for 24V systems and cannot be used in standard 230V mains voltage circuits. It is also not suitable for outdoor environments where moisture or dust exposure exceeds the IP40 protection rating.

Key specifications

• Supply voltage: 24V AC/DC
• Maximum switching current: 16A
• Mounting type: DIN rail (TH-35)
• Width: 2 modules (35mm)
• Protection rating: IP40

How to use

The timer should be installed by a qualified professional within an electrical distribution board on a standard DIN rail. Once mounted, the input and output wiring must be connected according to the provided wiring diagram, ensuring the 24V power supply is correctly matched. The desired time delay interval is set using the adjustment knob on the front panel, allowing the user to define how long the lights remain active after the trigger signal is received.

What to consider before purchase

• Verify that your lighting system operates on 24V voltage
• Ensure there is sufficient space for two modules in your electrical cabinet
• Check that the total load of the connected lighting does not exceed the 16A limit

Usage recommendations

For optimal performance and safety, ensure all connections are tightened securely and the device is kept in a dry, indoor environment. Regularly inspect the electrical cabinet to ensure the timer remains free from dust accumulation.
