Schneider Electric / MagneCraft W6225DSX-1 Solid State Relay

The Schneider Electric / MagneCraft W6225DSX-1 is a panel-mount solid-state relay engineered for industrial AC load switching applications. It accepts DC control voltage and uses SCR (Silicon Controlled Rectifier) technology to switch AC loads up to 25 A RMS. Optical isolation between input and output provides solid noise immunity in demanding industrial environments.

An integrated snubber circuit protects against transient overvoltages, while a red LED status indicator confirms input voltage presence. This device is discontinued; availability is limited to used or refurbished stock.
