Safe speed monitoring
Safe monitoring of speeds
The DD110S and DD111S speed monitors are designed for safety-related maximum speed monitoring. Typical applications include carousels or centrifuges. The DD111S is specially designed for the low rotational speed of wind turbines.
Both speed monitors can also be used for the operating mode "reduced speed" e.g. on machine tools.
The speed monitors are certified to EN 62061 / SIL 3 and EN ISO 13849-1 cat. 4 / PL e, even if non-safety-related standard sensors are used as pulse pick-ups.
When the safety output has been triggered, it can be reset again manually or automatically.
