SK3D-Safety Coupling-Extension
SK3D is an all-purpose safe coupling relay with three safe relaycontacts. It ensures the quick and safe deactivation of the moving parts of a machine in case of danger.
The SK3D couples safe signals of e.g. pulsed PLC’s to the periphery for galvanic isolation and power adjustment.
SK3D can also be used as an extension module for our safety relais, safety timer and compact safety controller.
