Solid State Relays RSR72 – reliable control of AC loads

Solid State Relays RSR72 Relpol are components dedicated to industrial applications where reliable and maintenance-free switching of alternating current loads is required. They are characterized by high mechanical resistance and elimination of electromechanical interference, which translates into longer life and stable system operation. The RSR72-60D75-H model stands out for its ability to switch on at zero crossing, which minimizes the risk of damage and interference in the circuit. The integrated heatsink ensures efficient heat dissipation, even under high loads.

Characteristics and application

RSR72 relays are designed for mounting on a 35mm DIN rail, and their compact design with a built-in heatsink facilitates integration with existing installations. A wide range of control voltage (4…32V DC) allows for easy adaptation to different control systems. The load voltage of 600 V AC enables use in applications with high voltage requirements. These relays are used in many branches of industry, including:

• Packaging machines and plastics processing
• Temperature chambers
• Injection molding machines and industrial mills
• Industrial car washes
• Lighting control systems
• Control cabinets and automation systems

Key features and benefits

• Zero-crossing switching: Reduces electromagnetic interference and extends the life of devices. Allows to avoid voltage surges during switching under load.
• Integrated heatsink: Provides effective heat dissipation, enabling operation with the full rated load (75A at 600V AC). Eliminates the need for additional cooling elements.
• Wide control voltage range (4…32V DC): Enables easy integration with various control systems, without the need for additional voltage converters.
• High resistance to environmental conditions: Operation at temperatures from -30...+80°C and IP20 protection class ensure reliability even in harsh industrial conditions.
• No moving parts: Eliminates the risk of mechanical wear and ensures quiet operation of the device. Increases reliability and reduces maintenance costs.
• Resistance to vibrations and chemicals: Enables operation in an aggressive industrial environment, without the risk of damage or failure.

Remember to maintain a minimum distance of 30mm when mounting several RSR72 relays next to each other, to ensure optimal cooling and avoid overheating of the components.
