Safe Coupling Relay SK3D
Safe Coupling Relay SK3D
Description
SK3D is an all-purpose safe coupling relay with three safe relay contacts. 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 relays, safety timer SCB and our compact safety controller TALOS.
SK3D is an all-purpose safe coupling relay with three safe relay- contacts. 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 can be used as contact extension for a basic device of the SR-Series. Therefore is no feedback circuit necessary.
The SK3D is specially designed and certified for the use in furnaces and ancillary equipment in continuously mode according to EN 50156-1 and EN 746-2.
