SIEMENS SIE 3RQ4118-2AF0 - Output coupler with plug-in relay, 230 V AC/DC, 1 changeover con

The Siemens SIRIUS coupling relay series offers compact, high-performance interface solutions for safe signal transmission between control and load circuits. The particularly slim design makes the relays ideal for applications with limited space in the control cabinet and at the same time enables a high packing density.

The devices impress with their reliable electrical isolation and high switching capacity and are optimised for industrial automation tasks. Thanks to plug-in designs and well-conceived accessories, the devices are especially quick and easy to install, maintain and replace.

Typical areas of application include signal amplification and decoupling and adaptation of control signals in machine and plant engineering, where value is placed on robustness and operational reliability. ...
