Timer switch with reserve AD1NO-R-15M

The ABB AD1NO-R-15m 2CSM222461R1000 time switch is a daily analog timer designed to automate the switching on and off of electrical loads according to preset schedules. It operates at 230 V AC and 50/60 Hz, features 1 channel with a normally open (NO) contact, and allows programming in minimum intervals of 15 minutes.

This version includes a 100-hour power reserve via a rechargeable NiMH battery, allowing the time reference to be maintained during power outages. Its compact 1 DIN module format makes installation easy in residential, commercial, and tertiary electrical panels for controlling lighting, heating, ventilation, irrigation, or other compatible loads.

Daily programming via analog dial

The AD1NO-R-15m uses a 24-hour programming dial with 96 segments. Each segment represents a 15-minute interval, allowing different on and off periods to be set throughout the day.

The program repeats automatically every 24 hours, making it especially suitable for installations that must maintain the same operating schedule every day.

Programming is carried out directly from the front of the device, without the need for software, mobile apps, or external configuration systems.

100-hour power reserve

One of the main features of this AD1NO-R version is its backup operation. ABB incorporates a rechargeable NiMH battery with autonomy of up to 100 hours.

The battery charges while the time switch is powered from the mains and helps maintain the time reference during power interruptions. In this way, a temporary loss of supply does not require immediate readjustment of the timer clock.

ABB specifies the backup battery as an internal, non-removable component.

16 A normally open contact

The time switch has 1 normally open contact with a switching capacity of 16 (4) A at 250 V AC. ABB specifies a maximum capacity of 16 A for resistive loads and 4 A for inductive loads.

The connected load must remain within the admissible values established by the manufacturer. For higher-power loads or those with high inrush currents, it may be necessary to use the time switch to control a suitable contactor.

Capacity according to load type

ABB specifies different load limits depending on the connected technology:

• Resistive load: up to 16 A.
• Inductive load: up to 4 A.
• Maximum switching power: 4000 VA.
• Incandescent lamps: up to 2500 W.
• Fluorescent lighting: up to 1200 VA.
• Low-voltage halogen lamps: up to 2000 VA.
• 230 V halogen lamps: up to 2500 W.
• CFL energy-saving lamps: up to 900 VA.
• LED lighting: up to 100 VA.

Permissible power depends on the electrical behavior of the load and its inrush currents, so the specific limit indicated for each technology must be respected.

Three-position manual selector

In addition to programmed operation, the ABB AD1NO-R-15m includes a manual selector with three operating modes:

• 0: permanent off.
• Automatic: operation according to the configured program.
• I: permanent on.

This selector allows the programmed schedule to be temporarily overridden without changing the dial segments, a particularly useful function during maintenance work, testing, or specific needs for continuous operation.

Operating accuracy

ABB specifies a running accuracy of ±1 second per day at 23 °C. The programmed switching accuracy is approximately ±5 minutes.

The minimum switching interval is 15 minutes, so the device is intended for time-based automation where second-level or very short minute sequences are not required.

230 V AC power supply

The timer operates with a nominal supply of 230 V AC at 50/60 Hz. Its own power consumption is low, with a value specified by ABB of ≤ 0.5 W.

The technical documentation indicates an operating voltage range of approximately 195 to 253 V AC, considering the tolerances allowed around the nominal voltage.

Compact 1 DIN module format

The AD1NO-R-15m occupies only 1 DIN module, making it easy to install in panels where available space is limited.

• Width: 17.5 mm.
• Height: 90 mm.
• Depth: 66 mm.
• Approximate weight: 0.075 kg.

It is installed on a DIN rail, together with miniature circuit breakers, residual current devices, contactors, and other modular panel components.

Terminals for conductors up to 4 mm²

ABB specifies captive screw terminals with a maximum conductor cross-section of 4 mm². The indicated tightening torque is approximately 0.3 Nm.

Connection must be made following the electrical diagram supplied by ABB, distinguishing the supply terminals from the output contact terminals.

IP20 protection

The time switch has an IP20 protection rating and protection class II. It is intended to be installed inside a panel or suitable enclosure that provides the protection level required by the installation site.

ABB indicates pollution degree 2 for the intended operating conditions.

Operating temperatures

• Operating temperature: -10 to +45 °C.
• Storage temperature: -20 to +60 °C.

These limits must be respected to ensure proper operation of the timing mechanism and backup battery.

Applications of the ABB time switch

The AD1NO-R-15m allows loads that must operate on a repetitive daily schedule to be automated. Typical applications include:

• Scheduled switching of lighting on and off.
• Outdoor lighting and shop windows.
• Heating systems.
• Ventilation.
• Pumps and small compatible equipment.
• Automatic irrigation systems.
• Electrical equipment in homes and residential communities.
• Automation of commercial installations.
• Time control of loads via contactor.

Applicable standards

ABB specifies the product in accordance with EN 60730-2-7, relating to automatic electrical controls and timers used in domestic and similar applications.

Installation must be carried out by qualified personnel, following the manufacturer’s wiring diagram and ensuring that the terminals are not accessible without tools once installation is complete.

Simple programming with backup during power outages

The ABB AD1NO-R-15m offers a simple and compact solution for automating electrical loads through repetitive daily programming. Its 15-minute intervals make it easy to set schedules directly from the front dial, while the manual selector allows the load to be kept on or off independently of the program.

The 100-hour power reserve is a major advantage over the version without a battery, as it maintains the time reference during supply interruptions. With 1 NO contact rated at 16 A, 230 V supply, and a format of only 1 DIN module, it is especially suitable for electrical panels where a reliable, compact, and easy-to-configure analog time switch is required.
