Product information

Description

The Siemens 3RQ2000-1CW01 is a high-performance coupling relay engineered for industrial control environments. Designed as part of the SIRIUS 3RQ2 series, this device serves as a critical interface for coupling control signals to and from a controller. It features three hard gold-plated changeover contacts, which ensure exceptional contact reliability even when switching low currents. With its wide-range voltage input capability, this relay offers universal compatibility across various electrical systems, effectively reducing the need for multiple device variants and optimizing inventory management.

Advantages

The primary benefit of this coupling relay is its versatility provided by the wide-range voltage input of 24V to 240V AC/DC, allowing it to function seamlessly in diverse industrial setups. The inclusion of hard gold-plated contacts provides superior signal integrity, making it an ideal choice for applications requiring high precision and reliability at low current levels. Furthermore, the industrial enclosure is designed for durability, while the removable screw terminals facilitate rapid installation, efficient wiring, and simplified maintenance or device replacement processes.

Suitable for

  • Industrial automation and control systems
  • Signal coupling between controllers and field devices
  • Applications requiring reliable switching of low-current signals
  • Electrical systems with varying voltage requirements

When it may not be suitable

This relay may not be suitable for high-power switching applications that exceed the rated current capacity of the contacts. Additionally, if your specific installation environment requires rapid, tool-less push-in connectivity, you may prefer a version with spring-type terminals rather than the screw terminals provided on this model.

Key specifications

  • Contact configuration: 3 changeover contacts
  • Contact material: Hard gold-plated
  • Voltage range: 24V to 240V AC/DC
  • Connection type: Screw terminals
  • Series: SIRIUS 3RQ2

How to use

Installation should be performed by qualified personnel in accordance with local electrical standards. The device is designed for mounting within an industrial control cabinet. Begin by securing the relay to the mounting rail. Connect the control and load wiring to the designated screw terminals, ensuring that all connections are tightened to the specified torque to prevent loose contacts. Verify that the input voltage matches the 24-240V AC/DC range before energizing the system. The removable terminal blocks can be detached to simplify the wiring process before final assembly.

What to consider before purchase

  • Verify that the 3-pole configuration meets your circuit requirements.
  • Ensure the screw terminal connection type aligns with your existing wiring standards.
  • Confirm that the load requirements do not exceed the relay's switching capacity.
  • Check the available space in your control cabinet for proper mounting.

Usage recommendations

For optimal performance and longevity, ensure the relay is installed in an environment free from excessive dust, moisture, and extreme vibrations. Regularly inspect the screw terminal connections during scheduled maintenance to ensure they remain secure.
