The 5–200V SSR-25DD Solid State Relay Module is a reliable semiconductor-based switching device designed for controlling DC loads using a low-voltage DC input signal. Unlike conventional electromechanical relays, this SSR operates without mechanical contacts or moving components, helping provide silent operation, faster switching, and extended service life.
The module uses solid-state switching technology to electrically control the load from an isolated low-voltage control signal. Its compact construction makes it convenient for applications where space, reliability, and low maintenance are important.
With a 25A rated load current, the SSR-25DD supports a 3–32V DC trigger voltage and can switch DC loads in the 5–200V DC range. Its design helps reduce electromagnetic interference while providing dependable switching performance.
