THEBEN
Frequently asked questions
Common questions about THEBEN from 3G Electric.
What is the difference between the Theben TR-610-TOP-2 and TR-612-TOP-2 timer switches?
The Theben TR-610-TOP-2 and TR-612-TOP-2 are both DIN rail-mounted digital timer switches with a 7-day schedule, SPDT contact, and 56 programmable events. The primary difference is the supply voltage: the TR-610-TOP-2 is available in 12/24V AC, 120V AC, and 220V AC versions, while the TR-612-TOP-2 is specified for 120V AC operation. Both models are not astronomic and require manual programming of switching times. They are rated IP20 and carry CE and UL listings. The TR-610-TOP-2 and TR-612-TOP-2 are suitable for time-based control of lighting, HVAC, and industrial equipment where a 7-day schedule with a single SPDT output is sufficient.
Does the Theben TR-644-TOP-2-RC-120V-240V support astronomic switching?
Yes, the Theben TR-644-TOP-2-RC-120V-240V includes astronomic functionality. This allows the timer to automatically adjust switching times based on sunrise and sunset for the installation's location, which is useful for exterior lighting and other applications where daylight changes seasonally. The device operates on 120-240V AC and provides SPDT contacts. It supports up to 800 programmable events and uses a 365-day electronic timer. The TR-644-TOP-2-RC is rated IP20 and carries CE and UL listings. It is programmed via text-oriented user guidance on the display and can be set up without a mains connection.
What are the supply voltage options for Theben SEL-172-TOP-2 timer switches?
The Theben SEL-172-TOP-2-12/24V operates on 12/24V AC. This model features a 7-day schedule, SPDT contacts, and 56 programmable events. It includes astronomic functionality for automatic seasonal adjustment based on sunrise and sunset. The SEL-172-TOP-2 is rated IP20 and carries CE and UL listings. For applications requiring higher supply voltages, Theben offers other timer switch families such as the TR-610-TOP-2, which is available in 120V AC and 220V AC versions, and the TR-644-TOP-2-RC-120V-240V, which operates on 120-240V AC. The correct model depends on the control voltage available in the panel and the required number of events and astronomic features.
How many programmable events do Theben DIN rail timer switches support?
The number of programmable events varies by model. The Theben TR-610-TOP-2, TR-612-TOP-2, and SEL-172-TOP-2 series support up to 56 events. The Theben TR-644-TOP-2-RC-120V-240V supports up to 800 events. Event capacity determines how many on/off operations can be scheduled within the programming cycle. Models with 56 events are typically used for standard 7-day scheduling of lighting or HVAC, while the 800-event capacity of the TR-644-TOP-2-RC is suited to more complex sequences or 365-day schedules. All these timer switches are DIN rail-mounted, rated IP20, and carry CE and UL listings.
What is the IP rating and mounting type for Theben TR-610-TOP-2 timer switches?
The Theben TR-610-TOP-2 timer switches have an IP20 rating and are designed for DIN rail mounting. IP20 indicates protection against solid objects larger than 12.5 mm but no protection against water. This rating is typical for devices installed inside electrical panels or control cabinets. The DIN rail mounting allows the timer to be installed alongside other modular devices on standard 35 mm rail. The TR-610-TOP-2 is available in 12/24V AC, 120V AC, and 220V AC versions, each with a 7-day schedule, SPDT contact, and 56 programmable events. The devices carry CE and UL listings and feature text-oriented user guidance on the display.
Can Theben timer switches be programmed without a mains connection?
Yes, Theben timer switches such as the TR-610-TOP-2, TR-612-TOP-2, TR-644-TOP-2-RC, and SEL-172-TOP-2 can be fully operated and programmed without a mains connection. This allows configuration before installation in the panel. The devices include a preset date and time and provide text-oriented user guidance on the display. Programming without mains power is useful for pre-commissioning and for adjusting schedules in the field. The timer switches are rated IP20 and carry CE and UL listings. They are designed for DIN rail mounting and are available in various supply voltages and event capacities to suit different control requirements.
