Solid State Relays RSR72 – reliable control of AC loads

The RSR72-28A30-H solid state relay is a component dedicated to switching single-phase loads in industrial and automation applications. It features zero-crossing switching, which minimizes electromagnetic interference and extends the lifespan of both the relay and the connected devices. The integrated heatsink provides effective heat dissipation, allowing operation with loads up to 30A at 240V AC.

Construction and application

The RSR72 relay is designed for mounting on a 35mm DIN rail, making it easy to integrate with existing control systems. Its robust construction and lack of moving parts guarantee high reliability and resistance to vibration and shock. This makes it ideal for demanding industrial environments, such as packaging machines, injection molding machines, and industrial washers. The ability to control both AC voltage (90…280 V AC) makes the relay versatile and easy to adapt to different control systems.

Key features and benefits

• Zero-crossing switching: Reduces electromagnetic interference (EMI) and extends the life of devices. This is particularly important in applications sensitive to interference, such as precision electronics.
• Integrated heatsink: Provides effective heat dissipation, allowing operation with higher load currents without the risk of overheating. This simplifies cooling system design and reduces the cost of additional components.
• Universal input voltage: Support for a control voltage of 90…280 V AC allows easy integration with various control systems without the need for additional transformers or converters.
• High mechanical resistance: The lack of moving parts increases resistance to damage caused by vibration, shock, and frequent switching.
• Wide range of applications: Ideal for controlling heaters, motors, lighting, and other electrical devices requiring precise and reliable switching.
• Safety: Compliance with standards ensures safe operation of the device in various working conditions.

The RSR72-28A30-H relay is a solid solution for professionals looking for a reliable component to control AC loads in industrial applications. Its versatility, durability and high performance make it an ideal choice for both installers and end users.
