The RM1A60A25 is an industrial, single-phase solid state relay designed for zero-switching control of resistive, inductive, and capacitive loads. It operates with a rated voltage of 600VACrms, handles a rated current of 25A, and accepts a wide control voltage range of 20 to 280VAC or 22 to 48VDC. Key features include a high blocking voltage of 1400Vp, a built-in varistor for transient protection, and an LED for input status indication. With its antiparallel thyristor output and robust design, this relay is well-suited for heavy industrial applications requiring reliable AC load control.
