Safety relay for use with light grids and
safe time functions
In addition to monitoring the emergency stop
and safety door circuits, the PSR-ESL4,
PSR-ESAM4/8X1 and PSR-ESD-30 modules
are also suitable for the evaluation of
semiconductor outputs of light grids and laser
scanners. The PSR-ESD modules have time
functions with a dropout delay, and you can
choose between a safety relay with a
predefined delay time and a safety relay with
an adjustable delay time.
The modules are protected against any
subsequent manipulation of the setting
elements by means of an adhesive label.
