Contact extension for light grid applications
28/10/2013 Phoenix Contact Ltd
The PSR-URM4L contact extension device from Phoenix Contact is highly suited for light grid applications. It allows users to efficiently process safety-related OSSD signals of a light grid as floating contacts, therefore supporting safety-relevant circuits up to PLe.The contact extension device is specifically designed for use with Electro-sensitive protective equipment (ESPE) such as light grids. Such systems normally include switched-mode OSSD signals that make it possible to detect cross-circuits in the cabling. The relay is resistant to test pulses generated by the CFSE. This allows for the implementation of applications that comply with PLe or SIL 3 without the need to reconnect the device to the external device monitoring circuit.
