Digital Timer Switch DATA MICRO+

The Orbis DATA MICRO+ digital time switch, reference OB172012N, is a 230 V modular programmer designed to automate an electrical circuit using second, daily, or weekly programs. It features one volt-free changeover contact 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 occupies 2 modules in width. Programming is carried out via an LCD screen and an icon-guided menu, making it easy to configure schedules for lighting, irrigation pumps, HVAC, signaling, and other electrical equipment. It also includes a power reserve of up to 4 years, automatic summer-winter time changeover, and temporary or permanent manual override.

Daily and weekly programming with up to 32 programs

The Orbis DATA MICRO+ can store up to 32 programs to set on and off times throughout the day or week. This allows the installation to be adapted to different days and time slots without the need for manual switching.

Programming has a minimum resolution of 1 second, providing high precision for applications that require short operations or activation at a specific time.

One volt-free changeover circuit

Reference OB172012N corresponds to the single-circuit DATA MICRO+ version. It incorporates a normally open and normally closed volt-free changeover contact, with a switching capacity of 16(10) A at 250 V AC.

The contact is made of AgSnO2 and allows direct control of different types of loads within the maximum ratings specified by Orbis.

Programmable pulses from 1 to 59 seconds

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

This function expands its use in applications such as sirens, buzzers, signaling, temporary relay actuation, or other equipment that only needs to remain active for a few seconds.

Holiday period of up to 99 days

The programmer includes a special holiday period configurable for up to a maximum of 99 days. During this interval, the usual programs are disabled without the need to delete them from memory.

This feature is especially useful in offices, shops, schools, and other facilities that remain closed for certain periods.

Temporary or permanent manual override

The output status can be changed manually from the programmer itself. The DATA MICRO+ allows a temporary on or off override, which changes automatic operation on a one-off basis, or a permanent manual state.

These functions make maintenance tasks, testing, or situations where the programmed schedule is temporarily not desired much easier.

Automatic summer-winter time changeover

The clock includes summer and winter time changeover management. It can be configured to perform the change automatically according to the European Union calendar, programmed in a custom way, or left disabled.

This function ensures that on and off times are correctly maintained throughout the year without having to manually adjust the clock at each seasonal change.

Power reserve of up to 4 years

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

In this generation of the DATA MICRO+, Orbis specifies an internal non-replaceable lithium battery.

LCD screen with icon-guided programming

The programmer features an LCD screen that displays the time, day, and operating status of the circuit. The menu system uses icons to guide the user through setup.

The time format is 24 hours and the clock accuracy reaches ±1 second every 24 hours at a reference temperature of 23 °C thanks to its quartz oscillator.

Sealable transparent cover

The front controls are protected by a sealable transparent window. This feature allows the information on the display to be checked visually while also helping to prevent unauthorized changes to the programming.

For this reason, the DATA MICRO+ is especially suitable for electrical panels in residential communities, shops, offices, schools, and other installations accessible to different users.

Suitable for different types of loads

The normally open contact supports different maximum ratings depending on the type of load connected:

• 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.

For loads with high inrush currents, it is especially important to ensure that the limits specified by the manufacturer are not exceeded.

Modular DIN rail format

The Orbis DATA MICRO+ is designed for DIN rail mounting and occupies 2 modules, equivalent to approximately 35 mm in width. Its overall dimensions are 35 x 88 x 65 mm and its net weight is 135 g.

Connection is made using screw terminals and accepts conductors with a maximum cross-section of 4 mm². The specified maximum tightening torque is 0.8 Nm.

230 V power supply

Reference OB172012N corresponds specifically to the 230 V AC ±10% powered version, with a nominal frequency of 50/60 Hz. Its own consumption is 7.3 VA, equivalent to approximately 1.2 W.

Orbis offers other DATA MICRO+ references for different supply voltages, so it is important to check the product code when replacing an existing programmer.

IP20 protection for electrical panels

The DATA MICRO+ has an IP20 protection rating according to EN 60529 and Class II when correctly installed. It is designed for installation inside electrical panels protected against water and access to live parts.

Its normal operating range is between -10 and +45 °C, while the operating limit specified by Orbis extends from -30 to +50 °C.

Applications of the Orbis DATA MICRO+

Its weekly programming, pulse function, and volt-free contact make the DATA MICRO+ suitable for numerous residential, commercial, and professional installations:

• Indoor and outdoor lighting control.
• Electric pumps for irrigation systems.
• Operating schedules for HVAC in offices.
• School sirens.
• Signs and signage.
• Electrical equipment in shops and public buildings.
• Automation of circuits in compatible industrial installations.
