Solid State Relays RSR72 – Reliable AC Load Control

The RSR72-24D40-H solid state relay is a component dedicated to switching AC loads. The device is characterized by zero-crossing switching, which minimizes interference and extends the lifespan of both the relay and the connected devices. The integrated heatsink ensures effective heat dissipation, increasing stability and reliability in demanding industrial conditions.

Construction and Application

The RSR72 relay is a single-phase design, intended for mounting on a 35mm DIN rail. Its main task is to isolate control circuits from power circuits, eliminating the risk of damage and ensuring safe system operation. Thanks to the lack of moving parts, the relay is characterized by high resistance to vibration, shock, and the absence of electromagnetic interference. This makes it ideal for use in harsh industrial environments, such as packaging machines, injection molding machines, or temperature chambers.

• Zero-crossing switching: Ensures smooth switching of the load, reducing inrush currents and minimizing interference in the electrical network.
• Wide control voltage range: Accepts control signals of 4…32V DC, ensuring compatibility with various control systems.
• Integrated heatsink: Enables efficient heat dissipation, ensuring stable operation even under high loads.
• Mechanical durability: The lack of moving parts translates into a longer lifespan and lower failure rate.
• DIN rail mounting: Facilitates installation and integration with existing automation systems.

Parameters and Characteristics

The RSR72-24D40-H relay is designed to operate with loads at 240 V AC and a rated AC1 current of 40A. Thanks to this, it finds application in a wide range of industrial devices and machines. It is worth noting the possibility of choosing relays with AC or DC control input, allowing you to tailor the device to specific application needs. Additionally, high resistance to environmental conditions (operating temperature -30...+80°C) guarantees reliable operation even in demanding industrial environments. The IP20 protection degree provides basic protection against touch and contamination.
