FF AZ-112 Twilight Switch 16A 24V DIN Rail Mount

The FF AZ-112 is a precision-engineered twilight switch designed to automate lighting systems by monitoring ambient light levels. This device ensures that connected lighting circuits are activated at dusk and deactivated at dawn, providing a seamless solution for energy management in both residential and industrial environments. Engineered for installation on standard DIN rails, it integrates easily into existing electrical distribution boards, offering a robust 16A load capacity and operating on a 24V power supply.

Advantages

The primary benefit of the FF AZ-112 is its ability to significantly reduce energy consumption by ensuring lights are only operational when natural light is insufficient. Its reliable sensor technology provides consistent performance, eliminating the need for manual intervention or complex timer programming. The compact DIN rail design allows for space-efficient installation within control cabinets, while the high-quality internal components ensure long-term operational stability and durability in various environmental conditions.

Suitable for

• Automatic control of outdoor lighting for pathways and building perimeters
• Illumination management for parking lots and industrial zones
• Energy-efficient operation of indoor lighting in areas with low natural light
• Integration into smart home or building automation systems requiring 24V control

When it may not be suitable

This device is specifically designed for 24V electrical systems and cannot be used in standard 230V mains circuits without appropriate voltage conversion. It may also be unsuitable for locations where the light sensor is exposed to direct artificial light sources, such as street lamps or security floodlights, as this can cause the switch to cycle incorrectly.

Key specifications

• Operating voltage: 24V
• Maximum load capacity: 16A
• Mounting type: DIN rail
• Function: Dusk-to-dawn light sensing

How to use

The device should be installed by a qualified electrician within a suitable electrical enclosure. The light sensor must be positioned in an area where it can accurately detect ambient daylight without being obstructed or influenced by the light it controls. Once mounted on the DIN rail and wired according to the provided schematic, the sensitivity threshold can be adjusted to match the specific lighting requirements of the installation site.

What to consider before purchase

• Verify that your electrical system operates on a 24V supply
• Ensure the total load of the connected lighting does not exceed 16A
• Confirm that the installation location allows for proper sensor placement

Usage recommendations

For optimal performance, ensure the external light sensor is kept clean and free from debris, and avoid placing it in locations where shadows or flickering light sources might trigger false switching.
