DRS24D25 is a single-phase DIN-rail solid-state relay designed for industrial control applications requiring reliable switching of AC loads up to 25A at 280 Vac. The relay features zero-cross turn-on technology with a tight ±14V zero-cross window for low EMI, optical isolation between control and load circuits, and an integral heat sink for thermal management. It incorporates dual LEDs for visual diagnostics (control and output status), a normally closed status output for system fault detection, and automatic overvoltage protection that switches ON at 950V to clamp high voltage surges. The DRS24D25 is ideal for heating control, motor control, and industrial process control applications, offering easy tool-free mounting on DIN rails or direct panel mounting with excellent transient suppression and low on-state voltage drop of 0.9V.
