Exploring the technology....

Safety PLC´s with integrated safe motion control according to PL e of EN 13489 und SIL3 of the EN 61508

Conventionally safety technology and safety engineering:Protecting the machines working area - stop in case of entering the safety zone

Until now - Safe operation requires to seal off the operational area!

A violation of the saftey zone results a stop of the plant!

The BBH Products technology provides a safe reduced operating ofthe machine ...

BBH Products technology provides...• Safe limited speed • Safe limited revolutions• Safe limited torque • Safe limited acceleration / braking ramps• Safe position• Safe limited operational zone• Safe direction• Safe cam • Management of safety-related equipment• Safe indexing, jogging operation• Safe stop, safe operational stop• Safe standstill• Safe communication

Innovation in safety technology:Safe Motion Control

Functional monitoring of the driveOnly cutoff in case of failure

Safety related devices and non safe equipment can be managed by the SafetyPilot and SMX
