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.

The SK3D is specially designed and certified for the use in furnaces and ancillary equipment in continuously mode according to EN 50156-1.

SK3D can also be used as a extension module for our safety relays and safety timer.
