High ease of use, more space in the control cabinet, quicker production starts, more compact machines with shorter safety distances and reduced downtime: With the clever ReLy safety relay, you get even more out of your application, and that with high safety at performance level e. So don’t rely on just any safety relay – use the ReLy from SICK. Thanks to clearly defined areas of application, selecting the right variant is simple as can be.
