Pepperl+Fuchs has introduced a new a compact and fl exible stand-alone programmable safety controller with an expansion port that enables it to grow with the application. The device provides four redundant safe inputs and two independent safe electronic outputs. It runs on standard 24 VDC and allows any safe device with dry contacts or electronic safe outputs to be used. Removable terminals simplify installation and fi eld service, and an intuitive drag-and-drop application interface makes it easy to confi gure even complex safety operations in a few minutes. When the confi guration is downloaded into the safety controller, documentation is automatically created, and all necessary data is backed up on a memory card.
