Littelfuse TDBL120AL is a digital time delay relay with an output load rating of 10 A resistive at 120/240 V AC and 28 V DC, and 1/3 hp at 120/240 V AC. It features an octal 8-pin plug-in termination type and operates on an input AC line frequency of 50/60 Hz. The relay offers a repeat accuracy of ±0.1% or 20 ms, and a setpoint accuracy of ≤±5% vs ambient temperature and operating voltage. With a power consumption of ≤3.25 W, the relay has a reset time of ≤50 ms and a time delay type of digital. It has a long life with electrical durability of 1 x 10⁶ cycles and mechanical durability of 1 x 10⁷ cycles. The recycle time is ≤150 ms and the initiate time is ≤60 ms. The setting accuracy is ±2% or 50 ms, and indication is provided through an LED that signals when the relay is energized.
