KSCD60D4-12 SSR 12VDC Input 60VDC 4A DC Solid State Relay Industrial

The KSCD60D4-12 Solid State Relay (SSR) is a high-reliability DC switching device designed for efficient, silent, and maintenance-free control of DC loads in industrial and electronic automation systems. Built using solid-state semiconductor technology, it eliminates mechanical wear, ensuring long service life, fast response, and consistent performance under repeated switching cycles.

This relay operates with a 12VDC control input, supporting a control voltage range of 10VDC to 14VDC. With a low maximum input current of 25mA, it is compatible with PLC outputs, microcontrollers, and industrial control circuits, providing stable and efficient triggering performance.

On the output side, the KSCD60D4-12 is designed for DC load switching with a voltage range of 0 to 60VDC. It supports a continuous load current range of 0.02A to 4A, making it suitable for a wide variety of DC-powered applications such as solenoids, motors, LED systems, and industrial DC loads.

The relay features a fast switching response with a maximum turn-on time and turn-off time of 3ms, ensuring precise and responsive control in automation environments. Its transient overvoltage protection of 66V peak helps safeguard connected equipment from voltage spikes and switching disturbances.

For safety and reliability, the KSCD60D4-12 provides 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 operation even in electrically noisy or harsh industrial environments.

Because it is a solid-state device, it offers silent operation, no arcing, and no mechanical wear, significantly extending operational life compared to traditional electromechanical relays. It is particularly suitable for applications requiring frequent switching or continuous duty cycles.
