Solid State Relays

The S202S11F is a solid-state relay designed for applications that require high contact ratings and fast switching speed. The versatile S202S11F can be used for commonly used switching circuits, such as motors, lamps, LEDs, and fans.

Application Field

The S202S11F solid-state relay’s AC/DC load switching capabilities make it an ideal choice for many applications. It has an AC current rating up to 10A and a DC current rating up to 16A. It is a low-switching loss device with a low voltage drop of just 0.65V. The S202S11F offers great flexibility with three different control signal options ranging from 0.1V to 0.7V.

The S202S11F is suitable for applications such as pumps, motor motor controls, solenoid valves, and gate drives. Additionally, it is well suited for temperature, flow, and pressure control in factory automation and process control systems. Its wide range of features make it a reliable choice for many industries, including medical, automotive, and industrial.

Working Principle

The S202S11F is a solid-state relay that uses a control signal to turn on or off. It is built using a MOSFET and a zero crossing detector. The MOSFET functions as a switch and the zero crossing detector prevents the MOSFET from turning on at incorrect times. When the control signal is turned on, the MOSFET receives the power and the load current flows, turning the load on. When the control signal is turned off, the MOSFET is no longer provided with the power and the load current no longer flows, turning the load off. This rapid switching action allows the S202S11F to switch load currents quickly and be used in applications requiring fast switching.

The S202S11F is designed to be highly reliable, with built-in protections such as short circuit protection, transient surge protection, and overtemperature protection. The wide range of features make the S202S11F a reliable and cost-effective choice for most industrial and consumer applications.
