Solid State Relays – Reliable AC Load Control

The RSR72-28A10-H solid state relay is a component designed to switch AC loads in industrial and automation applications. It utilizes zero-crossing switching technology, which minimizes interference and ensures smooth control. The integrated heatsink effectively dissipates heat, increasing the reliability and lifespan of the device, especially with intensive use.

This model stands out for its versatility – it can be controlled by both AC (90…280 V) and DC voltage. The relay is designed to work with loads at 240 V AC and a rated current of up to 10 A. This makes it suitable for a variety of applications, from controlling heaters and motors to lighting and heating systems.

Application and benefits for installers and end users:

• Versatility: The ability to control both AC and DC voltage provides flexibility in control circuit design.
• High reliability: The absence of moving parts eliminates the risk of mechanical wear, which translates to a longer lifespan and fewer failures.
• Quiet operation: The lack of mechanical components ensures silent operation of the relay, which is important in many applications.
• Protection against interference: Zero-crossing switching technology minimizes electromagnetic interference, ensuring stable operation of connected devices.
• Efficient cooling: The integrated heatsink ensures optimal heat dissipation, even under heavy loads, which increases safety and extends the component's life.
• DIN rail mounting: Allows for quick and easy mounting in control cabinets and electrical distribution boards. It is recommended to maintain a minimum distance of 30mm when mounting several relays next to each other to ensure adequate air circulation.
• Wide operating temperature range: The relay maintains its properties in a temperature range from -30°C to +80°C, allowing it to be used in harsh environmental conditions.

RSR72 Relpol relays are characterized by high mechanical strength and resistance to vibration and shock, making them an ideal solution for demanding industrial applications – such as injection molding machines, industrial mills or packaging machines. A wide range of available models allows you to match the relay parameters to the specific needs of a given project.
