Littelfuse KRD93115MA is a reliable and efficient microcontroller-based time delay relay. It has an output load rating of 10 A resistive at 125 V AC, 5 A resistive at 230 V AC and 28 V DC, and 1/4 hp at 125 V AC. With quick connect terminals, it offers easy installation. The relay is encapsulated and consumes less than 2 W of power. It operates within a humidity level of 95% relative (non-condensing). Its input tolerance ranges from -15% to 20%. The repeat accuracy is ±0.5% or 20 ms, whichever is greater. The reset time is less than 150 ms and the initiate time is less than 40 ms with a maximum of 750 operations per minute. It provides reliable performance with a life expectancy of 1 x 10^5 electrical and 1 x 10^7 mechanical operations. The KRD93115MA relay also offers protection against reverse polarity for DC units and has an input DC ripple of less than 10%.
