SR4C is a safety switching device that combines instantaneous and delayed contacts in an extremely compact housing. This means that dangerous parts of a system can be switched off quickly and safely in an emergency.
At the same time, other circuits can still be supplied with voltage for up to 30 seconds, for example to move a tool to the rest position or to enable the braking of following parts.
