It is suitable for even the smallest systems, with an expansion port that enables it to grow with the application. The unit 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 is as simple as wiring a conventional safety relay. Removable terminals simplify installation and field service. An intuitive drag-and-drop application interface makes it easy to configure even complex safety operations quickly. When the configuration is downloaded into the safety controller, documentation is automatically created, and all necessary data is backed up on a memory card, which makes it easier to add or replace a safety controller.
