Littelfuse TDB24AL is an octal 8-pin plug-in time delay relay with a 10A resistive load rating and a 1/3 hp rating. It operates at input frequencies of 50/60 Hz with input tolerance ranging from -15% to 20%. The repeat accuracy is ±0.1% or 20ms, and the setpoint vs ambient temperature and operating voltage remains within ±5%. With a power consumption of ≤3.25W, the relay has a reset time of ≤50ms and a recycle time of ≤150ms. It features a digital time delay type, offering a life cycle of 1 x 10^6 electrical and 1 x 10^7 mechanical. The relay also has an undervoltage trip voltage capability of 023s in 1s increments. The initiate time is ≤60ms, and the setting accuracy is ±2% or 50ms. The LED indication shows when the relay is energized.
