Littelfuse TDBH120AL is a plug-in digital time delay relay with a load rating of 10 A resistive @ 120/240 V ac and 28 V dc. Its octal 8-pin termination type ensures easy installation. With an input AC line frequency of 50/60 Hz and a tolerance of -20% to 10%, it offers precise repeat accuracy of ±0.1% or 20 ms. Setpoint vs ambient temperature and operating voltage has a variance of ≤±5%. The relay consumes ≤3.25 W of power and has a quick reset time of ≤50 ms. Its digital time delay type and accurate setting accuracy of ±2% or 50 ms provide reliable functionality. The LED indicator confirms relay energization. Its electrical and mechanical life spans are 1 x 10⁶ and 1 x 10⁷ respectively. The relay's recycle time is ≤150 ms and it has an undervoltage trip voltage of 230 s in 10 s increments. Initiate time is ≤60 ms.
