2 MOD.DUO D 230V Analogue Time Switch

The Orbis DUO D analog time switch, reference OB291032, is a modular electromechanical timer designed to automate the daily switching on and off of electrical circuits. It operates at 230 V, features a 24-hour front dial with a minimum programming interval of 30 minutes, and includes a changeover contact rated at 16(4) A at 250 V AC.

Its 2-module format allows direct installation on a 35 mm DIN rail inside the electrical panel. Programming is carried out easily using the dial tabs on the front face, and the manual selector lets you choose between automatic operation, permanent ON, and permanent OFF. Reference OB291032 corresponds specifically to the daily model without power reserve.

Daily programming with a 24-hour dial

The Orbis DUO D uses a 24-hour front dial to set the circuit switching periods. The configured program repeats automatically every day, making it especially suitable for installations that need to maintain a similar schedule throughout the week.

The dial includes 48 programming tabs. Each one represents a 30-minute interval, allowing different operating periods to be defined throughout the day without the need for digital screens, apps, or external devices.

Minimum switching time of 30 minutes

The minimum programmable duration is 30 minutes. This resolution is suitable for controlling lighting, heating, pumps, filtration systems, irrigation systems, and other equipment that must be switched on for relatively long periods.

Orbis specifies an approximate switching accuracy of ±5 minutes for the daily dial.

Easy-to-read front dial

The DUO range is characterized by a front dial that makes it easy to visually check the time and the programmed periods once the unit is installed in the panel.

Programming is done by moving the tabs to the positions corresponding to the on and off periods, providing an intuitive system especially suitable for users who prefer analog configuration.

Three-position manual selector

The front panel includes a manual control that allows the circuit status to be changed without altering the programmed schedule:

• I - Permanent ON: keeps the circuit connected regardless of the program.
• 0 - Permanent OFF: keeps the circuit disconnected.
• A - Automatic: the output follows the schedules set on the dial.

These positions are useful for maintenance tasks, holiday periods, functional testing, or situations where the automatic program needs to be temporarily overridden.

Version without power reserve

Reference OB291032 corresponds to the DUO D, that is, the daily version without battery or power reserve. When the power supply is interrupted, the mechanism stops advancing until power is restored.

The tabs physically retain the configured program, but after a power outage it may be necessary to readjust the current time on the dial.

16(4) A changeover contact

The DUO D features a changeover contact with a capacity of 16(4) A at 250 V AC. This configuration allows the use of either the normally open or normally closed contact depending on the circuit requirements.

The maximum load that can be connected depends on the nature of the load, so the limits specified by Orbis for each type of receiver must be respected.

Compatible with different lighting technologies

• Incandescent lamps: up to 3000 W.
• Fluorescent lamps: up to 1200 VA.
• 12 V AC low-voltage halogen lamps: up to 2000 VA.
• 230 V AC halogen lamps: up to 3000 W.
• Energy-saving lamps: up to 900 VA.
• LED lighting: up to 200 VA.

For equipment with high inrush currents, it is especially important to verify that the actual load is within the manufacturer's specifications.

2-module DIN modular format

The time switch occupies 2 DIN modules, equivalent to 35 mm in width, and is installed on a 35 mm DIN rail. Its overall dimensions are approximately 35 x 88 x 65 mm, making it easy to integrate alongside protection devices and other control elements in the electrical panel.

Connection is made via terminals prepared for conductors up to 4 mm².

Low own consumption

The DUO has an own consumption of less than or equal to 0.5 W. Its mechanism offers a timekeeping accuracy of up to ±1 second per day at a reference temperature of 23 °C.

IP20 protection for electrical panels

The Orbis DUO D has an IP20 protection rating according to EN 60529 and Class II under correct mounting conditions. It is designed to be installed inside electrical panels or suitable enclosures that protect the terminals and live parts.

Its operating temperature range is between -10 and +45 °C.

Applications of the Orbis DUO D

Daily programming and the changeover contact make the OB291032 suitable for many installations where equipment must operate according to set schedules:

• Swimming pool filtration systems.
• Indoor and outdoor lighting.
• Shop windows and illuminated signs.
• Heating systems.
• Water pumps.
• Irrigation systems.
• Equipment in homes and residential communities.
• Offices and commercial premises.
• Public buildings.
• Compatible agricultural and industrial applications.

Simple daily programming to automate circuits

The Orbis DUO D OB291032 offers a simple solution for automating circuits that repeat the same schedule every day. The front dial makes both programming and visual checking easy, while its 30-minute intervals allow different operating periods to be configured within a single day.

Its 16(4) A changeover contact, three-position manual selector, and installation in only 2 DIN modules make it a practical timer for residential, commercial, and professional installations.

Important: reference OB291032 corresponds to the DUO D version without power reserve. For a daily version with battery and a reserve of more than 150 hours, Orbis offers the DUO QRD. The connected load must always comply with the limits indicated by the manufacturer.
