Littelfuse TDM120AL is a digital time delay relay with an octal 8-pin plug-in termination type. It has a load rating of 10 A resistive at 120/240 V ac and 28 V dc, and 1/3 hp at 120/240 V ac. The input AC line frequency is 50/60 Hz with a tolerance of -20% to 10%. The repeat accuracy is ±2% or 50 ms whichever is greater, and the setpoint versus ambient temperature and operating voltage is ≤±2%. It has a power consumption of ≤2.25 W and a reset time of ≤50 ms. The time delay type is digital, and it has a life of electrical: 1x10⁶ and mechanical: 1x10⁷ cycles. The recycle time during timing is ≤300 ms, and it offers indication with an LED that glows during timing while the relay is de-energized.
