Photocell switch AZ-112 I=16A, external hermetic probe fi 10, 1 module

Twilight switch – intelligent lighting control

This compact twilight switch AZ-112 is a reliable solution for automatically turning on and off external and internal lighting, depending on the light intensity. Ideal for both home and professional installations, it provides convenience and energy savings. The device is designed for mounting on a DIN rail, which simplifies integration with existing electrical infrastructure.

Functionality and application

The AZ-112 switch uses an external light-sensitive probe (with a diameter of 10 mm) to precisely detect the light level. This ensures that the lighting turns on automatically at dusk and off at dawn, eliminating the need for manual operation. The probe, thanks to its IP65 tightness, is resistant to weather conditions, allowing it to be placed outside the building. The device finds application in street lighting, squares, gardens, building facades, as well as in alarm and monitoring systems.

Advantages for the installer:

• Easy installation: Mounting on a standard 35 mm DIN rail ensures quick and trouble-free installation.
• Versatility: Can be used with various types of light sources (incandescent, halogen, LED, fluorescent).
• Sensitivity adjustment: Smooth adjustment of the switching threshold allows you to adapt the operation of the switch to specific lighting conditions.
• High reliability: Made of durable materials guarantees long-lasting and trouble-free operation.

Benefits for the end user:

• Energy saving: Automatic switching off of the lighting during the day allows you to reduce electricity consumption.
• Convenience: Eliminates the need to manually turn the lighting on and off.
• Safety: Increases the sense of security by automatically turning on the lighting after dark.
• Comfort: Provides comfortable use without the need to remember to operate the lighting.

Technical characteristics and construction

The AZ-112 switch is characterized by high quality workmanship and a solid construction. The relay output element ensures reliable switching of a load up to 16A at 230V AC. The device has a delay in switching on and off, which minimizes the impact of interference (e.g., lightning) on its operation. Adjustment of the activation threshold takes place in the range from 2 to 1000 lx, allowing for precise adaptation of the switch to individual needs. The length of the probe cable is 1 meter with the possibility of extension to 10 meters (requires making a connection in a hermetic box). The switch housing has a protection class of IP20, while the probe – IP65, providing protection against moisture and dust.

The supply voltage is 230 V AC, and the maximum load current is 16 A. The device allows you to connect loads up to 2000 W for incandescent bulbs, 1000 VA for fluorescent lamps with DUO compensation, 600 VA for fluorescent lamps and 250 W for LEDs. The brightness adjustment range is between 2 and 1000 lx, the turn-on delay is approximately 10 seconds, and the turn-off delay is approximately 20 seconds. The protection class of the switch is IP20, and the probe IP65. The length of the probe cable is 1 meter with the possibility of extension to a maximum of 10 meters.

Remember: when checking the operation of the switch, be sure to cover the entire probe tightly to avoid false readings caused by sunlight penetrating the housing!
