Light curtain monitoring
Safety of persons has the highest priority in manufacturing plants and facilities. This is why the monitoring of light curtains on machines and processing centres is a further important function of the electronic safety relay ESR.
A safety relay of the ESR5-NV3-30 series can be used for processing signals from output signal switching devices (OSSD) of a light curtain.
Expansion modules ESR5-NE… with five additional enable paths facilitate the expansion of safety relay enable paths.
Depending on the application, the highest safety demands compliant to EN ISO 13849-1 up to PL e, to IEC 62061 up to SIL CL 3, and to IEC 61508 up to SIL 3 can be achieved.
