## Summary description

The FF AZ-112-PLUS-24V is a twilight switch designed for automatic lighting control based on ambient light levels. It features a 16A switching capacity and operates on a 24V power supply. Designed for standard TH rail mounting, this device is ideal for industrial and residential automation systems, ensuring energy efficiency by activating lighting only when necessary.

## Long description

The FF AZ-112-PLUS-24V is a professional twilight switch engineered for the precise automatic control of lighting systems based on real-time ambient light intensity. Designed for seamless integration into electrical cabinets, this device mounts directly onto standard TH rails, providing a reliable solution for managing outdoor or indoor illumination. By monitoring light levels, the switch ensures that lighting is activated only when natural light falls below a set threshold, contributing to significant energy savings and operational efficiency in both residential and industrial environments.
Advantages
This twilight switch offers a robust 16A switching capacity, allowing it to handle substantial lighting loads with ease. Its 24V power supply compatibility makes it an excellent choice for low-voltage automation systems where safety and reliability are paramount. The device is built for durability and consistent performance, featuring a compact design that saves space on the DIN rail. By automating the lighting process, it eliminates the need for manual intervention, ensuring that areas are always illuminated exactly when required while preventing unnecessary power consumption during daylight hours.
Suitable for
Automatic control of street and garden lighting
Illumination management for parking lots and driveways
Energy-efficient lighting systems in industrial facilities
Low-voltage automation projects requiring 24V power
When it may not be suitable
This device is specifically designed for 24V systems and cannot be used directly with standard 230V mains power without appropriate transformers. It may also not be suitable for environments with extreme light interference, such as areas with high-intensity artificial light sources that could cause the sensor to trigger incorrectly.
Key specifications
Supply voltage: 24V AC/DC
Maximum switching current: 16A
Mounting type: TH-35 rail
Operating threshold: Adjustable light intensity levels
Contact configuration: Single-pole normally open
How to use
Installation should be performed by a qualified professional in accordance with local electrical regulations. The device is snapped onto a standard TH-35 rail inside a distribution board. Connect the 24V power supply to the designated input terminals and wire the lighting load through the switching contacts. Once installed, the sensitivity threshold can be adjusted using the integrated control dial to match the specific lighting conditions of the installation site. Ensure the external light sensor is positioned in a location where it can accurately detect ambient daylight without being obstructed or influenced by the light it controls.
What to consider before purchase
Verify that your lighting system operates on a 24V power supply
Ensure the total load of your lighting does not exceed the 16A limit
Check that you have sufficient space on your DIN rail for installation
Confirm the external sensor placement area is free from direct artificial light interference
Usage recommendations
For optimal performance, position the external light sensor away from direct artificial light sources, such as street lamps or security floodlights, to prevent the switch from cycling on and off unnecessarily. Regularly clean the sensor lens to ensure accurate light detection.
