Littelfuse TDBH120ALD is a reliable and efficient 11-pin plug-in relay with a load rating of 10 A resistive @ 120/240 V ac and 28 V dc, and 1/3 hp @ 120/240 V ac. It operates at an input AC line frequency of 50/60 Hz, with a tolerance range of -20% to 10%. With a repeat accuracy of ±0.1% or 20 ms, it ensures precise and consistent performance. Its power consumption is ≤3.25 W, and it has a quick reset time of ≤50 ms. The relay features a digital time delay type, with a recycle time of ≤150 ms. It also has an indication LED that shows when the relay is energized. With a long electrical life of 1 x 10⁶ cycles and mechanical life of 1 x 10⁷ cycles, it is highly durable. The relay's undervoltage trip voltage can be adjusted in 10 s increments, and it has an initiate time of ≤60 ms. The setting accuracy is ±2% or 50 ms, and it can handle a wide range of ambient temperatures and operating voltages with a tolerance of ≤±5%.
