    Description

    The Denki Seigyo Analog Voltage SSR Series provides smooth and proportional control of AC or DC power loads using analog voltage input signals. Designed for applications requiring precise heat, light, or motor control, these SSRs convert 0–10 V or 1–5 V DC control signals into continuous or phase-controlled output.
    Equipped with optical isolation, surge protection, and zero-cross or phase-angle switching, Denki Seigyo SSRs deliver fast, quiet, and durable operation ideal for modern automation and process control systems
