SSR-40 DA Solid State Relay Module 40A
SSR-40 DA Solid State Relay Module 40A is a high-performance electronic relay designed for switching AC loads using a low-voltage DC control signal. It accepts a 3–32V DC input and controls 24–380V AC loads with a maximum output current of 40A. Unlike mechanical relays, the SSR provides silent operation, fast switching, long service life, and reduced electromagnetic interference. Its compact design and bolt-mounting structure make it suitable for industrial automation, temperature control systems, heating equipment, motor control, and other applications requiring reliable and efficient DC-to-AC switching.
وحدة المرحل الإلكتروني SSR-40 DA بقدرة 40 أمبير هي مرحل إلكتروني عالي الأداء مصمم للتحكم بالأحمال الكهربائية المترددة AC باستخدام إشارة تحكم منخفضة الجهد DC. تدعم دخل تحكم من 3 إلى 32 فولت DC ويمكنها تشغيل أحمال بجهد 24 إلى 380 فولت AC وبتيار يصل إلى 40 أمبير. تتميز بتشغيل صامت وسرعة استجابة عالية وعمر تشغيلي طويل مقارنة بالمرحلات الميكانيكية التقليدية، بالإضافة إلى تقليل التداخل الكهرومغناطيسي. بفضل تصميمها المدمج وسهولة تثبيتها، تعد مناسبة لأنظمة التحكم الصناعي والتحكم الحراري وأجهزة التسخين والأتمتة الصناعية.
The SSR-40 DA Solid State Relay Module is a reliable electronic switching device designed to control high-voltage AC loads using a low-voltage DC control signal. Utilizing solid-state semiconductor technology instead of mechanical contacts, the relay offers silent operation, high switching speed, and extended service life.
The module accepts a control input voltage of 3–32V DC, making it compatible with microcontrollers, PLCs, Arduino boards, industrial controllers, and automation systems. It can switch AC loads ranging from 24V to 380V AC with a maximum load current of 40A.
Its solid-state design eliminates contact wear, reduces maintenance requirements, and minimizes electromagnetic interference. The relay is housed in a compact, durable enclosure and is designed for secure bolt mounting onto control panels or heat sinks.
For high-current applications, proper heat dissipation using a suitable heat sink is recommended to ensure reliable long-term operation.
