INCA DUO D 230V Analogue Timer Switch

The Orbis INCA DUO D analog time switch, reference OB330132, is a modular electromechanical programmer designed to automate the daily switching on and off of electrical circuits. It operates at 230 V, features a 24-hour dial with minimum programming intervals of 15 minutes, and includes a volt-free changeover contact rated at 16(4) A at 250 V AC.

Its 2-module format allows direct installation on DIN rail in electrical panels. Programming is simple, using the side tabs on the dial, making it especially suitable for lighting, heating, water pumps, irrigation systems, and other equipment that must repeat the same schedule every day.

24-hour daily programming

The Orbis INCA DUO D incorporates a daily programming dial that completes one cycle every 24 hours. The set schedule is automatically repeated every day while the device remains in automatic mode.

The dial has 96 tabs, providing 15-minute resolution. This makes it possible to set different on and off periods throughout the day without the need for digital menus, apps, or external equipment.

Minimum switching time of 15 minutes

Each tab represents a 15-minute interval, which is the programmer’s minimum switching time. This resolution is suitable for many domestic and professional applications where equipment must operate in time slots.

The switching accuracy indicated by Orbis for the daily version is approximately ±5 minutes.

Volt-free changeover contact

The INCA DUO D features an output with a changeover contact, normally open and normally closed. As a volt-free contact, it offers flexibility for integration into different control and command circuits.

Its breaking capacity is 16(4) A at 250 V AC, and the maximum loads specified by Orbis must always be respected according to the type of connected receiver.

Compatible with different lighting types

In addition to compatible control and automation equipment, the INCA DUO D can control different lighting technologies within the limits indicated by the manufacturer:

• 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 1000 VA.
• Downlights: up to 900 VA.
• LED lighting: up to 100 VA.

Daily version without power reserve

Reference OB330132 corresponds specifically to the INCA DUO D version without power reserve. Therefore, the unit does not include a battery to keep the clock running when the power supply is interrupted.

The programming set by the tabs remains physically configured, but after a power outage it may be necessary to reset the current time on the timer.

Compact 2-module DIN format

The INCA DUO D occupies only 2 DIN modules, equivalent to 35 mm in width. Its approximate external dimensions are 35 x 90 x 66 mm, making it easy to integrate alongside miniature circuit breakers, residual current devices, contactors, and other devices installed in the panel.

It is mounted on DIN rail and electrically connected via screw terminals. It accepts conductors up to 4 mm², and Orbis specifies a maximum tightening torque of 0.8 Nm.

Low power consumption

The mechanism has a power consumption of approximately 0.5 W, equivalent to 0.6 VA. In this way, the power required to keep the programmer operating is low.

Quartz mechanism accuracy

The INCA DUO uses quartz technology and offers a running accuracy of ±1 second every 24 hours at a reference temperature of 23 °C. This helps maintain stable daily programming under normal operating conditions while the unit is powered.

IP20 protection for panel installation

The programmer 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 protected against water and direct access to live parts.

Its operating temperature range is between -10 and +45 °C, while transport and storage temperatures range from -20 to +60 °C.

Applications of the Orbis INCA DUO D

Daily programming and the changeover contact make this time switch suitable for a wide variety of installations:

• Outdoor lighting.
• Shop windows and illuminated signs.
• Heating systems.
• Water pumps.
• Irrigation systems.
• Automatic feeding equipment.
• Installations in homes and residential communities.
• Shops, offices, and public buildings.
• Compatible agricultural and industrial applications.

Simple daily programming for electrical panels

The Orbis INCA DUO D OB330132 makes it possible to automate circuits that follow the same schedule every day using an easy-to-configure and easy-to-read analog system. Its 15-minute intervals provide enough flexibility to set several operating periods throughout the day.

The 16(4) A changeover contact, 2 DIN module format, and compatibility with different load types make it a practical solution for residential, commercial, agricultural, and professional installations.

Important: this reference corresponds to the daily version without power reserve. If the clock needs to keep running during power outages, Orbis offers the INCA DUO QRD variant with reserve. The connected load must always comply with the limits indicated by the manufacturer.
