Analogue Timer Switch 2 MOD.DUO QRD 230V

The Orbis DUO QRD analog time switch, reference OB292032, 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 offers a power reserve of more than 150 hours to keep the clock running during power outages.

Its 2-module format allows direct installation on a 35 mm DIN rail inside the electrical panel. The DUO QRD includes a 16(4) A changeover contact at 250 V AC, a replaceable rechargeable battery, and a three-position manual selector to choose between automatic operation, permanent ON, and permanent OFF.

Daily programming with 24-hour dial

The Orbis DUO QRD uses an analog daily programming dial that makes it easy to view the configured operating periods. The set cycle repeats every 24 hours, making it especially practical for equipment that must run every day on the same schedule.

The dial has 48 tabs, and each one represents a 30-minute interval. This makes it possible to program different on and off periods throughout the day without the need for screens, digital menus, or apps.

Minimum switching time of 30 minutes

The minimum duration of each programmable period is 30 minutes. Programming is carried out by moving the dial tabs corresponding to the time slots during which the circuit should remain active.

This mechanical system enables quick, visual setup, especially suitable for lighting, pumps, heating, pool filtration systems, and other equipment that does not require switching in minutes or seconds.

Power reserve of more than 150 hours

The QRD version incorporates a rechargeable battery that provides a power reserve of more than 150 hours. Thanks to this, the time mechanism can continue advancing even if there is a temporary interruption in the power supply.

This feature prevents the clock from immediately losing time during a mains outage and helps preserve the configured time cycle. The battery is replaceable following the procedure established by Orbis.

Three-position manual selector

The front panel includes a manual control that allows direct selection of one of three operating modes:

• I - Permanent ON: keeps the output contact closed regardless of the programming.
• 0 - Permanent OFF: keeps the circuit disconnected.
• A - Automatic: the circuit operates according to the schedules set on the dial.

This function allows the program to be temporarily overridden for maintenance tasks, holiday periods, testing, or any situation in which the load needs to be controlled manually.

16(4) A changeover contact

The DUO QRD features a volt-free changeover contact with a breaking capacity of 16(4) A at 250 V AC. This allows the normally open and normally closed contacts to be used according to the needs of the control circuit.

The maximum capacity depends on the type of load connected, so the loads recommended by Orbis must be respected.

• 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.

Compact 2-module DIN format

The timer is designed for mounting on a 35 mm symmetrical rail in accordance with EN 60715. It occupies 2 DIN modules, equivalent to 35 mm in width, making it easy to integrate alongside miniature circuit breakers, residual current devices, and other control and protection devices in the electrical panel.

Its overall dimensions are approximately 35 x 88 x 65 mm. Connection is made via terminals for conductors up to 4 mm².

Easy-to-read front dial

Unlike other analog timers with a side dial, the DUO range uses a front dial that allows the time and programmed periods to be checked quickly even after the device has been installed in the panel.

The transparent cover protects the programming elements and helps prevent accidental changes to the tabs during normal use.

Timekeeping accuracy

Orbis specifies a timekeeping accuracy of up to ±1 second per day at a reference temperature of 23 °C for the mechanism. For the daily dial, the indicated switching accuracy is approximately ±5 minutes.

The timer's own power consumption is equal to or less than 0.5 W, so the energy required to keep the mechanism operating is low.

IP20 protection and Class II

The DUO QRD has an IP20 protection rating according to EN 60529 and Class II under correct mounting conditions. It is intended to be installed inside an electrical panel that prevents access to the terminals once installation is complete.

Its operating temperature range is between -10 and +45 °C. Orbis also recommends avoiding installation immediately next to strongly inductive loads, such as contactors or transformers, which may generate intense electromagnetic fields.

Applications of the Orbis DUO QRD

Its daily programming and changeover contact make this time switch suitable for automating numerous domestic, commercial, and professional devices.

• Swimming pool filtration systems.
• Indoor and outdoor lighting.
• Shop windows and illuminated signs.
• Heating systems.
• Water pumps.
• Irrigation systems.
• Electrical equipment in homes and residential communities.
• Compatible commercial and industrial installations.
