Safety relay C581

Safety relays C581 with relay safety
contacts / enabling circuits provide
reliable switch off in hazardous situations
and make the efficient configuration of
continuous safety chains possible.
This safety relays carry out EMERGENCY­STOP switch off or protective door /
safety gate monitoring just as reliably as
the protection of pressing and punching
machines. Practical and user-friendly,
safety relays provide a complete and
economical safety chain for almost every
application.
