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 high mechanical strength and elimination of electromechanical interference, which translates into stable and long-lasting operation. The RSR72-60D20-H model features a load voltage of 600 V AC and a control input accepting signals of 4…32V DC. The integrated heatsink ensures efficient heat dissipation, increasing the device's reliability even with intensive use.

Construction and practical application

The RSR72-60D20-H relay is designed for mounting on a standard 35mm DIN rail. Its construction with a built-in heatsink simplifies installation and minimizes the need for additional cooling elements. The ability to switch at zero-crossing makes the relay ideal for controlling inductive loads such as heaters, motors, and transformers, reducing interference and extending the life of the equipment. A wide input voltage range (4…32V DC) ensures compatibility with various control systems.

Key advantages for installers and users

• High resistance to industrial conditions: Operation in a temperature range of -30 to +80°C and an IP20 protection class guarantee reliability even in harsh environmental conditions.
• No moving parts: Eliminates the risk of mechanical wear, increasing lifespan and reducing the need for maintenance.
• Zero-crossing switching: Minimizes electromagnetic interference and extends the life of inductive loads.
• Integrated heatsink: Simplifies installation and provides effective heat dissipation, improving operational stability.
• Versatility: Ability to control both DC and AC signals (depending on the model in the RSR72 series).
• Wide application: Ideal for controlling heaters, motors, lighting, and other electrical devices in the processing, mechanical, and many other industries.
• Safety: Compliance with standards ensures safe operation of the device.

RSR72 relays are used in many industries, such as plastics processing, food processing, as well as in packaging machines and temperature chambers. Their resistance to vibrations, shocks, and chemicals makes them a reliable solution even in the most demanding industrial applications.
