Finder 12.81.8.230.0000 12 Series 110…230 V, Astro-switch, NFC programming, 35 mm wide 1 Pole 16 Amp 230 Volt AC

Why Choose the Finder 12.81.8.230.0000 Digital Astro Time Switch?

The Finder 12.81.8.230.0000 is a sophisticated digital astronomical time switch designed to control electrical loads according to calculated sunrise and sunset times. As part of the Finder 12 Series, it calculates astronomical switching times from the date, time and geographical location, making it particularly suitable for lighting and other applications that need to follow changing daylight hours throughout the year.

This single-channel astro time switch provides a 1 CO (SPDT) changeover contact and supports both astronomical and conventional time-based control. Location can be configured using geographical coordinates, with postcodes available for setting locations in many European countries, while an offset function allows switching times to be adjusted relative to calculated sunrise and sunset.

With a 110–230 V AC nominal supply and a 16 A contact rating at 250 V AC, the 12.81.8.230.0000 provides dependable control for mains-powered installations. It can be programmed in Classic mode using the front joystick or in Smart mode using NFC communication with a compatible smartphone, while its 35 mm DIN rail mounting enables straightforward installation in distribution boards and control panels.

Reliable Astronomical Time Control for Lighting and Electrical Installations

Astronomical time switches such as the Finder 12.81.8.230.0000 calculate sunrise and sunset from the configured date, time and geographical location. This enables connected equipment to follow seasonal changes in daylight automatically without relying on an external light sensor.

The Finder 12.81 adds an offset function for switching before or after the calculated astronomical event and allows the Astro ON period to be overridden by conventional time-switch programming. NFC communication and front-panel joystick programming provide flexible configuration for new installations and subsequent schedule adjustments.

Typical Applications

• Street and municipal lighting control.
• Car park and external area lighting.
• Garden and landscape lighting.
• Illuminated signs and shop displays.
• Building exterior lighting systems.
• Electrical loads requiring sunrise and sunset-based switching.
