Safety Application Note with a possible implementation of the safety sub-functions SDI and PUS. Included is the basic circuit, safety-related block diagram, Sistema project, FluidDraw project, characteristics of suitable products and a product list of suitable products from Festo.

The conditions in many manufacturing areas, such as the splash
zone in food production plants, place a lot of stress on service unit
components. Cleaning agents and water jets attack the surfaces,
screws and pressure gauges. With this stainless steel protection
box, Festo offers a simple and low-cost solution to securely protect
the compressed air preparation components.

There are lots of good reasons to become a Festo

partnership for you and your customers!

An artificial bird is introduced which was developed using two new

features in biologically-inspired flight, active torsion and partially linear

kinematics. Active torsion rests on well established theoretical

predictions in unsteady aerodynamics. The concept of partially linear

kinematics is inspired by zoological observations on flying locusts.

When the wings flap upwards, the servomotor for the active torsion

turns the outer wing from a positive angle of incidence within

a short fraction of the flapping period into a negative angle of incidence.

Between the turning points the angle of torsion remains

constant. Numerical calculations confirm the expected benefits

compared to passive torsion.

Application Note for the realization of the safety sub-functions safe stopping and closing (SSC) and prevention of an unexpected start-up (PUS) with category 1 and up to PL c. This Application Note contains possible circuits for 5/3, 3/2 and 2/2 directional control valves and delockable check valves.
