## Long description

The Siemens 3RQ1000-1LW00 is a high-performance, force-guided coupling relay engineered for reliable signal transmission and industrial automation control. Designed for fail-safe operation, this device facilitates the coupling of control signals to and from controllers and serves as a contact extension for safety relay systems. Its robust construction and industrial-grade enclosure ensure consistent performance in demanding environments where precise switching is essential.
Advantages
This coupling relay offers significant flexibility through its wide-range voltage input, allowing it to operate seamlessly between 24V and 240V AC/DC. The inclusion of force-guided contacts enhances operational safety, meeting strict industry standards for reliability. The design features removable screw terminals, which simplify the wiring process and allow for quick and efficient device replacement during maintenance, minimizing system downtime.
Suitable for
Fail-safe coupling of control signals
Contact extension for safety relay systems
Industrial automation and control panels
Systems requiring SIL 2 / PL c safety certification
This relay may not be suitable for applications requiring high-current power switching, as it is primarily designed for signal transmission and control logic. It is also not intended for use in environments that exceed its specified safety certification levels or operating voltage range.
Key specifications
Contact configuration: 4 normally open (NO) and 1 normally closed (NC)
Operating voltage: 24V to 240V AC/DC
Safety certification: SIL 2 / PL c
Connection type: Screw terminals
Design: Force-guided contacts
To use the device, mount it securely within an industrial enclosure and connect the control lines to the designated screw terminals. Ensure that the input voltage matches the specified range of 24-240V AC/DC before energizing the circuit. The removable terminals can be detached to facilitate easier wiring or replacement without disturbing the main cabling.
What to consider before purchase
Verify that the 4NO/1NC contact configuration meets your specific circuit requirements
Ensure the safety certification level (SIL 2 / PL c) aligns with your system's safety design
Check that the physical dimensions and mounting style are compatible with your existing control cabinet layout
For optimal performance and longevity, ensure the relay is installed in an environment free from excessive vibration and extreme temperatures. Regularly inspect the screw terminals to ensure they remain tight and free from corrosion, especially in high-humidity industrial settings.
