## Long description

The Siemens 3RQ2000-2BW00 is a high-performance industrial coupling relay from the SIRIUS 3RQ2 series, engineered for the reliable isolation and switching of control signals between field devices and controllers. This versatile component features two changeover contacts and is designed to handle a wide control voltage range from 24V to 240V AC/DC, making it a flexible solution for diverse automation environments.
Advantages
This coupling relay offers significant operational benefits, including a universal wide-range voltage input that simplifies inventory management by reducing the number of required variants. The device is built for high contact reliability, ensuring consistent performance even when switching low currents. Its design incorporates removable spring-loaded terminals, which facilitate rapid wiring and allow for quick, efficient device replacement during maintenance, ultimately minimizing system downtime.
Suitable for
Industrial automation and control systems
Signal isolation between controllers and field devices
Applications requiring vibration-resistant connections
Systems where universal voltage compatibility is necessary
When it may not be suitable
This relay is intended for industrial control signal applications and may not be suitable for high-power switching tasks that exceed the specified contact ratings. It is also not designed for environments requiring specific hazardous area certifications unless explicitly stated for the installation site.
Key specifications
Contacts: 2 changeover contacts
Control voltage range: 24V to 240V AC/DC
Connection type: Spring-loaded terminals
Series: SIRIUS 3RQ2
Mounting: Standard industrial enclosure
How to use
The relay is designed for installation within industrial control cabinets. Begin by mounting the unit onto a standard DIN rail. Connect the control signal wires and the load circuit wires to the spring-loaded terminals by inserting the stripped wire ends directly into the push-in ports. Ensure that the control voltage applied is within the specified 24-240V AC/DC range. The removable terminal blocks allow for pre-wiring or easy replacement without disconnecting the entire system.
What to consider before purchase
Verify that the control voltage of your system falls within the 24-240V AC/DC range.
Ensure the two changeover contacts are sufficient for your specific switching logic.
Confirm that your wiring infrastructure is compatible with spring-loaded terminal connections.
Check the physical space requirements within your control cabinet for proper ventilation and access.
Usage recommendations
For optimal performance and longevity, ensure that the relay is installed in an environment free from excessive dust and moisture. Regularly inspect the spring-loaded terminals during scheduled maintenance to ensure connections remain secure and free from oxidation.
