DS1248WP-120IND+

The DS1248WP-120IND+ is a type of Real Time Clock (RTC) which is a clock that keeps exhibiting the correct time regardless of power cycles and the passage of time. Applications of this type of clock vary depending on the requirements and settings of the particular application. This article will outline the purpose and workings of the DS1248WP-120IND+ clock and will then go on to discuss some of its common application fields.

What is a Real Time Clock (RTC)

A Real Time Clock (RTC) is a type of clock which keeps track of the time. Unlike regular clocks and watches, a Real Time Clock runs off a special kind of low-power internal battery which allows it to maintain its timekeeping accuracy even when the main power goes out. The time is accurate to the minute, and can be easily adjusted if needed. A Real Time Clock is commonly used to keep record of events, or to help automate processes that can be set to occur at specific times.
