Littelfuse TDB24DL is a compact and reliable 8-pin plug-in time delay relay with a 10 A resistive load rating. It operates at 120/240 V ac and 28 V dc, with a tolerance of -15% to 20%. The repeat accuracy is ±0.1% or 20 ms, and the setpoint vs ambient temperature and operating voltage is ≤±5%. With a power consumption of ≤3.25 W and a reset time of ≤50 ms, this digital time delay relay ensures efficient operation. It has a long electrical life of 1 x 10⁶ cycles and mechanical life of 1 x 10⁷ cycles. The undervoltage trip voltage can be adjusted in 1 s increments. With an initiate time of ≤60 ms and a setting accuracy of ±2% or 50 ms, this relay offers precise performance. It also features an LED indication for relay energization and is reverse polarity protected for DC units.
