Finder 12.B2.8.230.0000 – 12 Series Time Switches

Why Choose the Finder 12.B2.8.230.0000 Annual Astro Time Switch?

The Finder 12.B2.8.230.0000 is an advanced 2-channel digital astronomical time switch designed for automated electrical switching based on time schedules, calendar dates and astronomical sunrise and sunset calculations. Part of the Finder 12 Series, this programmable device combines annual scheduling, Bluetooth connectivity, NFC programming and two independent changeover outputs in a compact DIN rail-mounted unit.

Featuring 2 changeover contacts rated at 16 A and 250 V AC, the Finder 12.B2 provides flexible control of lighting, electrical equipment and automation circuits. Its 110–230 V AC/DC nominal supply supports a range of electrical installations, while the astronomical programming function enables switching events to follow changing sunrise and sunset times throughout the year.

The device supports configuration through its onboard joystick or the Finder TOOLBOX smartphone app using Bluetooth and NFC technology. Advanced functions include annual, weekly, holiday, random, cyclic and pulse programming. Optional Bluetooth expansion modules and GPS time synchronisation accessories further extend its capabilities, making the Finder 12.B2.8.230.0000 suitable for sophisticated commercial, industrial and building automation applications.

Advanced Astronomical Scheduling and Wireless Programming

The Finder 12.B2.8.230.0000 combines conventional digital time switching with astronomical control, allowing connected equipment to operate according to calculated sunrise and sunset times. This is particularly useful for external lighting, illuminated signage and other applications where switching schedules should follow seasonal daylight changes. Annual programming allows different operating periods or individual dates to be configured, while random, cyclic and pulse functions provide additional control flexibility.

Programming can be completed locally using the integrated joystick or through the Finder TOOLBOX app. NFC enables configuration even when the time switch is not powered, while Bluetooth supports wireless configuration and communication with compatible expansion modules. The optional Finder 012.BG.8.230 GPS antenna provides time synchronisation, and compatible input/output accessories allow the installation to be expanded beyond the two integrated changeover contacts. This makes the device suitable for both standalone time control and more advanced distributed automation arrangements.

Typical Applications

• Commercial and industrial external lighting control.
• Street lighting and public area illumination.
• Car park and security lighting automation.
• Building façade and architectural lighting.
• Illuminated signage and advertising displays.
• Seasonal and holiday lighting schedules.
• Industrial machinery operating schedules.
• Commercial building electrical automation.
• Scheduled switching of pumps and auxiliary equipment.
• Energy management and automated electrical load control.
• Electrical distribution boards and DIN rail control panels.
• Applications requiring annual, weekly or astronomical switching programmes.
