Littelfuse MSM25W9 is an encapsulated analog time delay relay. It has an output load rating of 0.5 A steady state @ 25°C and 0.25 A steady state @ 60°C. With a power tolerance of ±10% and repeat accuracy of ±5%, it offers reliable performance. The relay can withstand humidity up to 95% relative non-condensing and has a minimum insulation resistance of ≥100 Ω. It has a time delay tolerance of ±15% and operates at an input AC line frequency of 50/60 Hz. The dielectric breakdown is ≥2000V terminals to mounting surface, providing safe operation. The output voltage drop is approximately 2.5V @ 0.5 A and the recycle time is ≤75 ms. It has a minimum output holding current of 40 mA and offers a setpoint vs ambient temperature and operating voltage of ≤±15%.
