Solid State Relays RSR72 – reliable control of AC loads

Solid State Relays RSR72 by Relpol are components dedicated to switching AC loads in industrial applications. They are characterized by instantaneous switching, allowing for precise process control. The RSR72-48D10-RH model features a load voltage of 480 V AC and a control input accepting signals of 4…32V DC. The integrated heatsink provides effective heat dissipation, increasing the device's reliability and lifespan.

Construction and practical application

RSR72 relays, thanks to their construction based on semiconductor elements, eliminate problems associated with mechanical components – the absence of electric arc and electromagnetic interference are key advantages. They are ideal for applications requiring frequent switching, where traditional electromagnetic relays could wear out faster. DIN 35mm rail mounting is standard in control cabinets, and the integrated heatsink simplifies installation. When mounting several relays next to each other, it is recommended to maintain a minimum distance of 30mm to ensure adequate air circulation.

These relays find wide application in various industries:

• Injection molding machines and packaging machines
• Industrial mills and car washes
• Temperature chambers
• Lighting control systems
• Switching three-phase motors (in combination with appropriate relays)
• Applications in plastics and food processing
