Photocell switch AZ-B I=16A, external hermetic probe fi 10, 2 modules

Smart lighting control with a dusk-to-dawn switch AZ-B

The AZ-B dusk-to-dawn switch is a reliable solution for automatically turning on and off outdoor lighting, such as street lighting, squares, building facades, or advertising displays. The device reacts to the light level, providing comfort and energy savings. Mounting on a DIN rail simplifies installation in a distribution box. The included external probe with a diameter of 10 mm allows for precise detection of changes in light intensity, and its hermetic design guarantees resistance to weather conditions.

Functionality and application

The AZ-B switch is designed to control circuits with a maximum current of 16A and a power of 250W for LED loads. The external probe allows mounting in a location with constant access to daylight, ensuring proper device operation. A potentiometer allows you to adjust the lighting switch-on threshold, adapting the switch-on time to individual needs. A delay circuit for switching on and off eliminates the risk of accidental activations caused by short-term disturbances, such as lightning.

• Lighting automation: Automatic switching on and off of lighting depending on the light level.
• Energy saving: Reducing energy consumption by eliminating the need for manual lighting control.
• Ease of use: No need to remember to turn lights on and off.
• Increased safety: Automatic lighting after dusk improves visibility and safety.
• Versatility: Can be used with various types of light sources (LED, bulbs, fluorescent lamps).

Technical specifications and construction

The AZ-B switch has been designed with durability and reliability in mind. The housing made of high-quality materials provides protection against external factors (IP20). The external probe has a protection class of IP65, which guarantees its tightness and resistance to moisture and dust. The device occupies 2 modules on a DIN rail (35 mm), which simplifies installation in standard electrical distribution boards. The maximum length of the sensor cable is 10 meters, which provides great freedom in choosing the mounting location of the probe. The rated switching current is 16A at a voltage of 230V and a frequency of 50Hz. The adjustable brightness range is from 2 to 1000 lx, and the hysteresis is approximately 15 lx. The activation delay for switching on is approximately 10 seconds, and for switching off – approximately 20 seconds.
