Standalone safety controller
By Mary Del
Pepperl+Fuchs’ VAS-2A8L-KE4-8SE programmable safety controller is a compact and flexible standalone solution, with an expansion port that enables it to grow with the application. The safety controller 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. Connecting safety devices to this controller is as simple as wiring a conventional safety relay, the company says. Removable terminals simplify installation and field service, while a drag-and-drop application interface makes it easy to configure even complex safety operations in just minutes. When the configuration is downloaded into the safety controller, documentation is automatically created, and all necessary data is backed up on a memory card.
