Siemens 3RQ2 Series Interface Relay, DIN Rail Mount

Ensure the safe and reliable transmission of digital signals to your automated systems with this optocoupler from Siemens. It's a semiconductor that uses a light-sensitive optical interface to relay signals. The unit connects isolated circuits that can't be joined directly due to differences in electrical potential or voltage. It guarantees information compatibility by applying the algorithms needed for the interaction of functional components in special control instruments. You can use this coupling relay to control and protect large radio-electronic and x-ray installations.

• Wide voltage range of 24V to 240V AC/DC for versatility
• Special monostable switching feature regenerates old pulses for more reliable operation
• DIN rail mounting for simple and secure installation
• Compact dimensions of 22.5 (length) x 91.6 (width) x 100mm (depth) to save space
• Long mechanical service life of 10 million switching cycles for long-lasting use

No. An optocoupler is not designed to switch loads like a relay. If your application needs you to perform this dual function, you'll need a relay with a built-in optocoupler.
