Product information

Description

The Relpol RSR72-24D20-H is a high-performance single-phase solid state relay engineered for precise and reliable switching in demanding industrial environments. By utilizing semiconductor technology, this relay eliminates mechanical wear, providing a robust solution for applications requiring frequent switching cycles. Its compact design and efficient thermal management ensure consistent performance when controlling AC loads, offering a significant upgrade over traditional electromechanical relays in terms of longevity and operational speed.

Advantages

This solid state relay offers silent operation, which is essential for environments where noise reduction is a priority. The absence of moving parts significantly extends the service life of the device and prevents contact arcing, leading to higher reliability in automation systems. Furthermore, the device supports a high switching frequency, allowing for rapid control of connected equipment without the risk of mechanical failure. Its wide control voltage range ensures compatibility with various standard industrial control signals.

Suitable for

  • Heating element control in industrial ovens and furnaces
  • Lighting system management and dimming applications
  • Control of solenoid valves and small motors
  • Automation systems requiring frequent switching

This relay is not suitable for applications involving high-voltage DC loads, as it is specifically designed for AC output switching. It should also not be used in environments where the ambient temperature exceeds the thermal ratings of the device without proper heat sinking, as overheating can lead to premature failure.

Key specifications

  • Output voltage: 240V AC
  • Control voltage range: 4-32V DC
  • Switching type: Single-phase
  • Technology: Semiconductor solid state

To use the Relpol RSR72-24D20-H, connect the control signal wires to the input terminals, ensuring the polarity is observed according to the 4-32V DC range. The load circuit should be connected in series with the output terminals. It is essential to ensure that the load current does not exceed the rated capacity of the relay to prevent damage. Always verify that all connections are secure and that the relay is mounted in a position that allows for adequate airflow.

What to consider before purchase

  • Verify that your load voltage matches the 240V AC output specification
  • Ensure your control signal source provides a voltage within the 4-32V DC range
  • Assess the need for an external heatsink based on your specific load current
  • Confirm the mounting space requirements for the relay housing
For optimal performance and longevity, it is recommended to install the relay on a suitable heat sink if the load current is high. Regularly inspect the electrical connections for tightness and ensure the operating environment remains within the specified temperature limits to maintain reliable operation.
