2CSM222431R1000 ABB AW1CO-R-210m Mechanical Weekly Time Switch 230 V AC

Why Choose the ABB AW1CO-R-210m Mechanical Time Switch?

The ABB AW1CO-R-210m is an analogue electromechanical weekly time switch designed for automatic control of electrical loads according to a repeating seven-day programme. Its straightforward mechanical dial provides reliable scheduled control for lighting, heating, ventilation, irrigation and other electrical equipment in residential and commercial installations.

The AW1CO-R-210m uses a 48-pin weekly programming dial with a minimum switching interval of 210 minutes (3.5 hours). A three-position manual selector provides permanent OFF, automatic and permanent ON operation, allowing the programmed schedule to be overridden whenever required.

Operating from a 230 V AC, 50/60 Hz supply, the timer provides a 16(4) A at 250 V AC switching capacity through a potential-free changeover contact. An integrated rechargeable NiMH battery provides a 150-hour power reserve, helping the unit maintain timekeeping during temporary mains interruptions.

Reliable Weekly Automatic Load Control

The ABB AW1CO-R-210m provides automatic switching according to a repeating weekly schedule without requiring digital menus or external programming equipment. Its mechanical 48-pin dial divides the week into 210-minute programming intervals, providing straightforward control where electrical equipment needs to operate at predetermined periods on different days.

The integrated 150-hour running reserve helps preserve timekeeping during temporary mains interruptions, while the potential-free changeover contact and three-position manual selector provide flexible circuit control. Its two-module DIN-rail enclosure makes the AW1CO-R-210m well suited to modular distribution boards and electrical control panels.

Typical Applications

• Commercial and public-building lighting schedules.
• Shop and display lighting control.
• Heating and ventilation equipment.
• Irrigation and watering systems.
• Residential weekly load scheduling.
• Weekly control of pumps, signs and other electrical equipment.
