Solid State Relays
Solid state relays (SSRs) are semiconductor switching devices that provide galvanic isolation between control and load circuits, offering silent, fast, and highly reliable switching without mechanical contacts. Our range includes panel-mount and DIN rail SSRs with rated currents from 2A to 40A, control voltages from 5VDC to 240VAC, and load volt...
Solid state relays (SSRs) are semiconductor switching devices that provide galvanic isolation between control and load circuits, offering silent, fast, and highly reliable switching without mechanical contacts. Our range includes panel-mount and DIN rail SSRs with rated currents from 2A to 40A, control voltages from 5VDC to 240VAC, and load voltages up to 240VAC. Key features include zero-cross and random-turn-on switching, built-in indicators, and integrated heat sinks. Models like the G3NA series offer robust photocoupler isolation for industrial loads, while the G3RV series provides compact terminal block solutions for mixed AC/DC control signals. The G3PA series adds DIN rail mounting with empty indicator and step-zero functionality. Accessories such as power cartridges and relay bases expand flexibility.
These SSRs are ideal for high-cycle applications in industrial automation, process control, HVAC systems, packaging machinery, and lighting control. They excel in environments requiring silent operation, such as medical equipment or clean rooms, and are commonly installed in control panels, motor control centers, and distributed I/O systems. Their solid-state design eliminates contact wear, making them perfect for resistive, inductive, and capacitive loads in manufacturing lines.
All SSRs comply with international standards including UL, CSA, and CE, ensuring global acceptance. They are compatible with major PLC and controller brands, including Omron, Siemens. The G3NA and G3PA series meet EN60947-4-3 for semiconductor controllers, while the G3RV series adheres to EN60950 for safety. Our inventory includes both standard and high-performance models, with detailed technical datasheets available for each part number.
We offer express worldwide shipping and personalized technical support from our team of electrical engineers. Our multilingual portal provides real-time pricing, stock availability, and comprehensive documentation for every SSR. Whether you need a single unit for prototyping or bulk quantities for production, we ensure fast delivery and expert guidance to match the right SSR to your application.
