Theben Selekta 174 top3 Digital Time Switch

2-channel weekly/astronomical program time switch for time and light control applications

Overview

This is a Theben Selekta 174 top3 digital time switch, a DIN rail-mounted, 2-channel timer designed for time and light control applications. Supporting both weekly and astronomical programs with 56 memory locations, this quartz-based time switch offers accurate ON-OFF scheduling for lighting and other electrical loads, with an LCD display and 4 touch buttons for local programming.

Key Features

  • 2-channel switching: Independent control of two channels with 56 total memory locations for programmed events.
  • Weekly and astronomical programs: Supports ON-OFF program functions based on either a weekly schedule or astronomical (sunrise/sunset) timing.
  • Quartz timing accuracy: Typical accuracy of ±0.25 s/day at 25°C, with a 10-year power reserve to retain settings during power loss.
  • Broad load compatibility: Rated for incandescent/halogen (2600W), energy saving lamps (1100W), various LED lamp loads, and fluorescent lamp loads (conventional, series-corrected, or parallel-corrected).
  • LCD display with text line: Provides clear local status and programming feedback via 4 touch buttons.
  • Compact DIN rail housing: 2-module width, IP20 rated, made from high-temperature resistant, self-extinguishing thermoplastic.
  • Protection Class II: Rated per EN 60730-1.
