Littelfuse TS1621 is an encapsulated time delay relay with a maximum output load rating of 1 A steady state and 10 A inrush at 60°C. It features 0.25 in. (6.35 mm) male quick connect terminals for easy termination. The relay operates at an input AC line frequency of 50/60 Hz with a tolerance of ±20%. It provides repeat accuracy of ±2% or 20 ms (whichever is greater) and insulation resistance of ≥100 Ω. The setpoint vs ambient temperature and operating voltage has a tolerance of ≤±10%. The time delay type is analog with a tolerance of ≤±10%. It has a dielectric breakdown of ≥2000V terminals to mounting surface. The output voltage drop is approximately 2.5 V at 1 A. The recycle time is ≤16 ms (after timing) and 0.1% of max. time delay or 75 ms (during timing). The minimum output holding current is 5 mA.
