Description:

The SSR-40DD DC to DC Solid State Relay Module (40A) is a high-performance switching device designed for efficient and reliable control of DC loads. It supports an input voltage range of 3V–32V DC and provides an output voltage of 5V–200V DC with a maximum load current of 40A.

Unlike traditional mechanical relays, this solid-state relay (SSR) uses semiconductor technology instead of moving contacts, ensuring faster switching speeds, silent operation, and a longer lifespan. The relay functions by using infrared light (IR LED) and a photometric coupler, allowing you to control high-voltage DC loads using low-voltage DC control signals safely and efficiently.

Built with four screw terminals for secure connections and enclosed in a durable protective plastic cover, the SSR-40DD ensures safe and convenient installation. Its compact size, high reliability, and low electromagnetic interference make it ideal for various industrial and automation applications.

Key advantages of the SSR-40DD include fast switching, low control power requirements, and long service life, making it a superior alternative to mechanical relays in performance and durability.

Whether you’re working on industrial control systems, motor control, or automation projects, the SSR-40DD Solid State Relay provides stable and efficient performance in demanding environments.
