3RQ3118-2AE01 SIEMENS

The 3RQ3118-2AE01 from Siemens is an output coupler designed to interface electronic control systems with load circuits. It features a plug-in relay with one changeover (CO) contact, ensuring versatile switching capabilities. The relay contacts are hard gold-plated, providing enhanced reliability and corrosion resistance for demanding applications. This output coupler utilizes spring-type terminals (push-in) for quick, secure, and vibration-resistant connections, simplifying installation and maintenance. It is suitable for both 115 V AC and DC voltage systems, offering flexibility in various power environments. With a narrow enclosure width of just 6.2 mm, it allows for high-density mounting on DIN rails, optimizing space utilization in control cabinets. The thermal current rating is 6A, making it suitable for controlling a range of inductive and resistive loads. This output coupler provides electrical isolation between the control circuit and the load circuit, protecting sensitive electronic components from voltage spikes and surges. It is commonly used in industrial automation, process control, and building automation systems to switch motors, valves, contactors, and other devices. The 3RQ3118-2AE01 is a reliable and compact solution for signal amplification and electrical isolation.
