FF AZ-112-LED dusk-to-dawn timer with external sensor, relay InRush 16 A (160 A/20 ms)

The FF AZ-112-LED dusk-to-dawn timer with external sensor and a high-capacity relay is designed to switch lighting automatically according to ambient light. The unit monitors natural light via an external photocell and activates or deactivates connected luminaires when predefined light thresholds are crossed. Its relay supports steady switching currents up to 16 A and can withstand inrush currents of 160 A for up to 20 ms, making it suitable for many LED and conventional lighting loads within those limits.

Advantages

This timer offers automatic light control based on an external sensor input, reducing the need for manual switching. The relay rating with defined inrush tolerance improves compatibility with LED drivers and fixtures that present high start currents. The compact control device is suitable for integration into outdoor lighting installations and controllers where reliable dusk-to-dawn operation is required.

Suitable for

• Automatic control of outdoor and perimeter lighting
• Garden and pathway illumination
• Façade and architectural lighting switched by ambient light level
• Retrofitting existing lighting circuits within the relay’s current limits

Key specifications

• Function: automatic dusk-to-dawn switching using external light sensor
• Relay steady switching current: 16 A
• Relay inrush tolerance: 160 A for 20 ms
• Compatibility: suitable for LED and conventional luminaires within relay limits
• Sensor type: external photocell input for ambient light detection

How to use

Install the external light sensor in a representative outdoor location away from direct artificial light sources and mount the timer unit in a protected electrical enclosure according to local wiring regulations. Connect the lamp circuit to the relay output and the external sensor to the sensor input following the provided wiring diagram. After wiring, verify the sensor orientation and allow the device to adapt to local dusk and dawn conditions; the timer will then switch the lighting automatically based on ambient light level.

Usage recommendations

Ensure the connected load does not exceed the steady switching current of the relay and consider the specified inrush tolerance when using LED drivers or large capacitive loads. Place the external sensor where it measures representative ambient light and avoid locations affected by nearby lamps or reflective surfaces to prevent incorrect switching.
