Users can realize the benefits of integrated safety logic without using a computer to program the device, says the vendor, saving time and simplifying set-up. Historically, safety logic has been implemented using either hardwire techniques with safety relays, or via more expensive safety programmable logic controllers. Flexi Controllers take advantage of the benefits of both technologies. Logic is implemented with rotary switches on the front of each module. Logical combinations with multiple modules are easily set based on how the modules are combined, the vendor says. A visualization tool, the Flexi Configuration Planner, helps simplify module selection and aid understanding of logic configuration possibilities.
