Contact extension for light grid applications

Contact extension for light grid applicationsPhoenix Contact’s PSR-URM4L contact extension device is 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.
