SSR-10DA Solid State Relay 10A (4-32 VDC Input)

Overview

Meet the SSR-10DA Solid State Relay — the silent, spark-free workhorse for your high-power switching needs. Unlike traditional mechanical relays, this solid-state relay uses semiconductor switching to handle up to 10A with no moving parts, no arcing, and virtually instant response. With a wide 4-32 VDC input range, it's perfect for microcontroller projects, industrial automation, and home automation systems. Whether you're controlling heaters, motors, or lighting, the SSR-10DA delivers reliable, quiet, and long-lasting performance.

Key Features

• 10A Switching Capacity: Handles up to 10 amps, suitable for a wide range of AC loads.
• Zero-Cross Trigger: Minimizes electrical noise and stress on connected devices by switching at the zero point of the AC waveform.
• Wide Input Range: 4-32 VDC input makes it compatible with 5V, 12V, and 24V logic signals from Arduino, Raspberry Pi, PLCs, and more.

MOKWN Recommendation

For most hobbyist and professional projects, the SSR-10DA is an excellent choice. If you need higher current handling, consider our SSR-25DA (25A) or SSR-40DA (40A) models. Always ensure your load current does not exceed the relay's rating and use proper heat sinking for continuous high-current operation.
