Specification

SEODescription

The QA1S38B-E Relay is a high-performance solid-state relay (SSR) designed for industrial automation and power control applications. Featuring a robust 38A load capacity, the QA1S38B-E 38A SSR supports a wide input voltage range of 4–32V DC for control signals and handles output voltages up to 480V AC, enabling direct integration with PLCs, sensors, and motor drivers. It operates within a temperature range of -30°C to +80°C, ensuring reliability in harsh environments. The QA1S38B-E offers fast switching, zero-noise operation, and long service life, making it ideal for heating systems, machinery, and heavy-duty equipment. However, its lack of built-in overvoltage protection and sensitivity to voltage spikes may require additional external safeguards. Its compact design and high-current handling distinguish it in industrial settings.
