Digital Timer Switch DATA MICRO 2+

The Orbis DATA MICRO 2+ digital time switch, reference OB171912N, is a 230 V modular programmer designed to automate two independent electrical circuits using second, daily, or weekly programming. It features two potential-free changeover contacts rated at 16(10) A, up to 32 programs, a pulse function from 1 to 59 seconds, and a special holiday period of up to 99 days.

It is installed on DIN rail and takes up only 2 modules. Programming is carried out through a guided icon-based menu and an LCD display that shows the information needed to set schedules and check operating status. It also includes lithium battery backup, automatic summer/winter time changeover, and the option to perform temporary or permanent manual overrides.

Two independent circuits

The OB171912N reference corresponds specifically to the DATA MICRO 2+ model, equipped with two independent output circuits. Each circuit has a potential-free changeover contact, allowing two different loads or devices to be controlled from a single time switch.

Each output offers a breaking capacity of 16(10) A at 250 V AC, providing a compact solution for installations where two circuits need to be automated without using two separate programmers.

Up to 32 daily or weekly programs

The DATA MICRO 2+ can store up to 32 on/off programs. Operations can be configured on a daily or weekly basis, adapting each installation to the required schedules.

This capacity is suitable for automating lighting, HVAC, irrigation pumps, sirens, signage, and other equipment that must be switched on or off at specific times.

Programming with 1-second precision

The programmer offers a minimum switching time of 1 second and programming precision to the second. Its internal clock uses a quartz crystal and provides a time accuracy of ±1 second every 24 hours at a reference temperature of 23 °C.

These features make the DATA MICRO 2+ suitable both for conventional time schedules and for applications requiring brief, precise switching operations.

Pulse function from 1 to 59 seconds

In addition to conventional on and off switching at a set time, the Orbis DATA MICRO 2+ allows pulses with a duration between 1 and 59 seconds to be programmed.

This function is especially useful for applications such as school bells, acoustic signaling, temporary relay activation, automation systems, and other equipment that only needs to remain connected for a few seconds.

Special holiday period of up to 99 days

The DATA MICRO 2+ allows a special holiday period of up to 99 days to be configured. During this interval, the usual programs can be temporarily disabled without needing to delete them.

Once the special period ends, the unit can resume the previously established schedule, making it easier to manage offices, schools, shops, and other facilities with closure periods.

Temporary or permanent manual override

The outputs can be operated manually from the programmer itself. Orbis allows temporary changes to the contact status or a permanent on/off setting when it is necessary to temporarily override the automatic program.

This function makes maintenance tasks, testing, and specific situations easier when the user needs direct control of the circuits.

Automatic summer/winter time changeover

The time switch includes management of the change between winter and summer time. It can be configured to perform the change automatically according to the European calendar, programmed in a custom way, or completely disabled.

This feature avoids the need to manually adjust the device time in installations where seasonal time changes are used.

Up to 4 years of power reserve

The Orbis DATA MICRO 2+ incorporates an internal lithium battery that provides up to 4 years of power reserve without mains supply. In this way, the clock and programs can be maintained during prolonged power outages or during periods when the unit is disconnected from the mains.

According to the official technical data sheet, the lithium battery in this version is not replaceable.

LCD display and icon-guided programming

The unit features an LCD display and an icon-based programming system that makes access to the different functions easier. The time format used is 24 hours.

The front panel includes a sealable transparent window, designed to make unauthorized tampering more difficult after the device has been programmed.

Potential-free changeover contacts

The two circuits of the DATA MICRO 2+ use potential-free NO/NC changeover contacts. This configuration expands integration possibilities in control circuits, as the contacts can be used to connect or disconnect different loads according to project requirements.

The contacts are made of AgSnO₂ and offer a rated switching capacity of 2 x 16(10) A at 250 V AC.

Suitable for different types of lighting

Orbis specifies the following recommended maximum loads for the normally open contacts:

• 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 600 VA.
• Downlights: up to 400 VA.
• LED lighting: up to 90 VA.

The permissible power must be selected taking into account the nature of the load and its possible inrush currents, especially when connecting electronic equipment or lighting systems.

Compact 2-module DIN format

The DATA MICRO 2+ is installed directly on DIN rail and occupies 2 modules, with an approximate width of 35 mm. Its overall dimensions are approximately 35 x 88 x 65 mm.

This format makes it possible to integrate two time channels inside the electrical panel using very little space, making it especially practical in installations with limited room for new devices.

230 V power supply

The OB171912N reference corresponds to the 230 V AC ±10% powered version, with a nominal frequency of 50/60 Hz. Orbis specifies a power consumption of 7.3 VA, equivalent to approximately 1.2 W.

Orbis also markets DATA MICRO + and DATA MICRO 2+ variants for other voltages, so the reference should always be checked before replacing an existing unit.

Applications of the Orbis DATA MICRO 2+

The combination of two independent circuits, weekly programming, and switching operations down to one second makes the DATA MICRO 2+ suitable for numerous residential, commercial, and professional applications.
