The UR20-PF-O safe power-feed modules are designed to safely switch off the power to all output modules when supplied from the safe power-feed slice. This function creates a “safety segment” that is managed locally by the UR20-PF-O safe power-feed module. The safety rated input works together with pulsed inputs to detect broken wires and short circuits. These safe power-feed modules go beyond standard safety relays by providing real-time feedback on which safety circuit is down. Weidmuller’s UR20-PF-O safe power-feed modules can be used in complex automation solutions by cascading multiple safe power-feed modules together. One UR20-PF-O module can manage up to 12 switchable output modules.
