Product Introduction
Product Overview & Core Design Positioning
The XRKC SSR‑DA series single‑phase solid state relay is a high‑performance, contactless DC‑to‑AC switching module professionally designed for industrial automation, heating systems, packaging machinery, and power control equipment. As a compact, high‑power flip‑style relay, it uses 3–32VDC control signals to safely switch 24–480VAC loads, providing maintenance‑free, silent, and fast switching for high‑frequency industrial applications. Available in 25DA, 40DA, 60DA, and 100DA current ratings, this series satisfies diverse power requirements while maintaining a consistent miniature footprint for easy layout and installation.
Built by Suosite Electrical, a leading industrial control component manufacturer with over 10 years of expertise, the XRKC SSR‑DA series emphasizes stability, durability, and thermal efficiency. Its fully sealed, dust‑resistant structure and advanced chip technology deliver reliable performance in harsh factory environments. Whether used for heating control, motor control, lighting regulation, or PLC output matching, this solid state relay improves system stability, extends equipment life, and reduces downtime.
Key Product Features
The XRKC SSR‑DA series comes with a full set of industrial‑grade features optimized for real‑world applications.
First, it uses a contactless electronic switching design with no moving parts, eliminating spark interference, mechanical wear, and noise, supporting hundreds of thousands of switching cycles.
Second, it supports wide voltage DC control (3–32VDC), compatible with PLCs, temperature controllers, and single‑chip outputs for universal system integration.
Third, it switches high‑voltage AC loads (24–480VAC), covering most industrial power environments without extra converters.
Fourth, it offers four power models (25DA, 40DA, 60DA, 100DA) to match small heaters to high‑power industrial loads.
Fifth, it features zero‑crossing triggering to minimize inrush current, protect loads, and extend service life.
Sixth, its miniature flip‑style housing saves cabinet space while ensuring good heat dissipation.
Seventh, it has fast response speed (microsecond level), ideal for high‑frequency automatic control systems.
Finally, it includes overcurrent, overvoltage, and overtemperature protection to enhance safety and stability.
Technical Advantages & Reliability Performance
Backed by Suosite Electrical’s R&D capability and strict quality control, the XRKC SSR‑DA series delivers exceptional technical advantages and long‑term reliability.
The core uses high‑power thyristor chips with low internal resistance, low heat generation, and strong overload capacity for stable full‑load operation.
Optoelectronic isolation between input and output ensures strong anti‑interference performance, maintaining stable switching near inverters and motors.
Advanced thermal design and thermally conductive materials lower operating temperature and improve long‑term durability.
Each unit undergoes 100% aging, insulation, and thermal testing before shipment, meeting industrial quality standards.
With a mean time between failures (MTBF) exceeding 100,000 hours, it supports 24/7 continuous operation.
Compared with traditional electromagnetic relays, it has longer life, higher efficiency, lower failure rates, and lower maintenance costs, making it widely trusted in automation.
