Weidmuller announces the release of the newest addition to their award-winning u-remote distributed I/O module line-up – the u-remote Safe Power-feed Modules. Unique to the market today, these compact safety modules feature integrated functionality to safely switch off power to all modules that are within a safety segment, eliminating the need for a safety controller. These modules meet stringent machine safety standards that include SIL 3 CL and Category 4 PL e, and can help increase efficiency and reduce wiring costs in applications by eliminating costly home run wiring while providing immediate feedback on the status of the safety circuit.
The new UR20-PF-O safe power-feed modules 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. Since this functionality is built into the modules, there is no need for expensive safety controllers and complex safety programs.
Weidmuller’s UR20-PF-O safe power-feed modules can be used in complex automation solutions by cascading multiple safe power-feed modules together. Available in 1 input, 2 inputs, or 2 inputs with delay, the UR20-PF-O safe power-feed modules can offer cost savings for a wide range of safety-related equipment. For example, consider the case of an emergency stop button along with a light curtain: the u-remote standard output modules used within the u-remote “safety segment” contribute to even more cost savings when compared to the traditional safety cards for every output. One UR20-PF-O module can manage up to 12 switchable output modules versus the more expensive system design that requires a safety module for each output module.
With safety levels of SIL 3 CL as per DIN EN IEC 62061, and Category 4 PL e as per DIN EN ISO 13849-1, Weidmuller’s UR20-PF-O safe power-feed modules offer the highest possible degree of machine safety protection.
