Safe speed monitoring

Safe speed monitoring

• For the safe detection of overspeed

• For reliably switching off drives in case of a fault
• Very large adjustable speed range
• Clearly visible LEDs for indicating operation, release, error and switching status
• Monitoring of two input channels with one separate output relay each

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.
