KSCD60D4-5T SSR 5VDC Input 60VDC 4A DC Solid State Relay Compact SIL

The KSCD60D4-5T Solid State Relay (SSR) is a compact, high-performance DC switching device designed for reliable and maintenance-free control of DC loads in automation and electronic systems. Built using solid-state semiconductor technology, it delivers silent operation, fast response times, and long operational life with no mechanical wear.

This relay operates with a 5VDC control input, supporting a control voltage range of 4VDC to 6VDC. With a low maximum input current of 25mA, it is fully compatible with logic-level outputs, microcontrollers, and low-voltage control systems, making it ideal for embedded applications and compact control designs.

On the output side, the KSCD60D4-5T is designed for DC load switching with a voltage range of 0 to 60VDC and a continuous load current capacity of up to 4A. This makes it suitable for a wide range of DC applications including motors, solenoids, LED systems, and industrial DC control circuits.

The relay provides fast and precise switching performance with a maximum turn-on and turn-off time of 3ms, ensuring responsive control in time-sensitive applications. It also features transient overvoltage protection up to 66V peak, helping protect connected devices from voltage spikes and switching disturbances.

For safety and reliability, the KSCD60D4-5T offers high electrical isolation with a dielectric strength of at least 2500Vrms between input and output, along with an insulation resistance of 1000M (at 500VDC). This ensures stable performance even in electrically noisy or demanding industrial environments.

Its compact SIL (Single In-Line) package allows for easy integration into PCB designs while saving space and simplifying assembly. As a solid-state device, it provides silent operation, high switching endurance, and long service life, making it ideal for applications requiring frequent or continuous switching.
