R-K Electronics, Inc. Time Delay Relays MCS-120A-4T

The MCS-120A-4T is an on-delay time delay relay from Quarktwin Technology Ltd., designed for use in various applications requiring time delay functionality. It operates with an input voltage range of 24 to 240V, accommodating both AC (50/60Hz) and DC power sources. The relay features adjustable time delays ranging from 100 milliseconds to 5 minutes, with a repeat accuracy of ±1% under fixed conditions. The output is solid-state, providing one normally open (1NO, Form A) contact rated for 1 Amp continuous at 25°C, with the ability to handle 15 Amps inrush non-repetitively. The device is designed for a minimum of 100,000 operational cycles, ensuring durability. It includes protection features such as a varistor and/or R-C network, and has a power consumption of 5VA. Physically, the relay is surface-mounted and can be terminated using screw terminals or .25,Äù push-on tabs. It operates within an ambient temperature range of 0°C to 65°C, with storage capabilities from -30°C to 85°C. The relay is epoxy filled for enhanced durability. The MCS-120A-4T is suitable for applications requiring reliable timing control in various environments.
