Littelfuse KRDS420 is an encapsulated relay with a 10A resistive output load rating at 125V AC and 5A resistive output load rating at 230V AC and 28V DC. It features 0.25 in. (6.35 mm) male quick connect terminals for easy termination. With an input AC line frequency of 50/60 Hz and a humidity tolerance of 95% relative non-condensing, it ensures reliable performance. The relay offers a repeat accuracy of ±0.5% or 20ms, insulation resistance of ≥100, and setpoint vs ambient temperature and operating voltage tolerance of ≤±5%. It consumes ≤2 VA of power, has a time delay tolerance of ≤±5%, reset time of ≤150ms, and initiate time of ≤40ms. It is designed with a microcontroller with watchdog circuitry for precise time delay. The relay has an electrical life of 1x10⁵ and mechanical life of 1x10⁷.
