SR3AD is certified for furnaces in continuous operation. Application for the process industry.
SR3AD is a safety switching device specially designed for sensors with antivalent logic (normally open / normally closed combination).
In case of danger, the moving parts of a machine or system can be quickly and safely shut down via three safe relay contacts.
