It features Bluetooth configuration capability. With a standard 2-module DIN rail mounting design, it includes a large LCD display, full operational prompts, time display accurate to 1 second, a minimum switching time of 1 minute, and 56 program slots. The astronomical clock function allows automatic calculation of sunrise and sunset times based on the input of local longitude and latitude, enabling automated operation that is more user-friendly and energy-efficient. It also allows adjustment of astronomical time according to customer needs. It has an independent relay output with a contact capacity of 16A 250V and uses screwless terminal blocks. Equipped with a memory card interface, programs can be edited and copied via memory card. Bluetooth connection is established by inserting the TOP3 memory card with Bluetooth functionality, enabling program configuration and modification via mobile phones and terminals. The manual function supports multiple predefined modes, features a high-brightness orange backlight, and includes a 10-year backup power supply to ensure programs are not lost during power outages.

The SELEKTA 171top3 RC synchronizes time by connecting to an external DCF or GPS antenna and uses GPS for additional positioning in astronomical programs. It includes three special programs (small annual programs), adjustable sunset deviation, and 84 program slots.
