Turck Safety Controller Replaces Relays

The Turck SC22-3 safety controller aims to be 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 of input types for safety and non-safety devices can be covered. Each input can be assigned to one of the three dual-channel safety outputs. A combination of LCD display and status LEDs provides the user with information at any time about power supply, error states, output status and communication with the PC.

The user can either configure SC22-3 directly via pushbuttons and LC display or via a PC. The graphical user interface on the PC allows users to create and document complex safety logic configurations with several inputs and outputs in a few minutes. Faulty devices or wiring faults are detected automatically.
