The SC22-3 safety controller is an efficient solution for connecting several safety devices to machine controls. The controller, developed by partners Banner Engineering, eliminates the need for several dedicated safety relays and integrates input devices, such as emergency stop switches, light screens, two-hand controls, interlocking switches or safety mats, in the machine control. A total of 22 contact-based and PNP solid-state inputs can be monitored, so that a broad range on input types for safety and non-safety devices can be covered. The controller is approved up to and including SIL 3 in accordance with IEC 62061 and IEC61508 as well as Performance Level e in accordance with ISO 13849-1. — Hans Turck GmbH & Co.
