Smart timing for lighting and equipment

The Baomain CN101A Time Switch Relay delivers precise, dependable timing for a wide range of loads, using a 12V DC/AC control input to switch up to 200-250V at 16A. With 28 on/off programs, you can design daily or weekly routines that fit your space without manual intervention. The flexible scheduling can adapt to weekdays, weekends, and seasonal changes, enabling you to align lighting and devices with your office hours or home activities.

Designed for real-world use, this timer features a clear backlit LCD that remains readable in bright daylight or dim corners. The slim panel-mount design fits standard control panels, with a 4 pin layout compatibility that makes installation straightforward for upgraded systems or DIY projects. The interface presents current status at a glance, helping you confirm you have activated the right program.

One standout benefit is the built in lithium battery backup. While the timer runs from main power, the backup preserves your schedules and helps you recover quickly if a brief outage interrupts programming. This means your routines stay consistent while you focus on other tasks. The timer's dual mode operation automatic scheduling and instant manual control lets you test a new setup or override a schedule for temporary needs without reprogramming.
