Littelfuse TDM230AL is a digital time delay relay with an octal 8-pin plug-in termination. It has 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 operates at an input AC line frequency of 50/60 Hz, with an input tolerance of -20% to 10% and a repeat accuracy of ±2% or 50 ms (whichever is greater). The setpoint vs ambient temperature and operating voltage is ≤±2%. It has a power consumption of ≤2.25 W and a reset time of ≤50 ms. It has a digital time delay type, with a life of electrical: 1 x 10⁶ and mechanical: 1 x 10⁷. The recycle time during timing is ≤300 ms, and it provides indication with an LED that glows during timing while the relay is de-energized.
