DS1683S+T&R

DS1683S+T&R is a total-elapsed-time and event recorder with alarm. It is an integrated elapsed-time recorder containing a factory-calibrated, low-temperature-coefficient RC time base that eliminates the need for an external crystal. Using EEPROM technology to maintain data in the absence of power, the DS1683 requires no backup power source. It features 32bit, non-volatile, elapsed time counter (ETC) monitors event duration with quarter seconds resolution and provides 34 years of total time accumulation. The DS1683 is ideal for applications that monitor the total amount of time that a device has been in operation and/or the number of uses since inception service, repair, or last calibration. It is also ideal for high-temp, rugged, industrial applications where vibration or shock could damage a quartz crystal, any system where time-of-use is important to track, power-on-time recorder.
