Intrinsically safe rotary encoder TWK

Safety relevant equipment must be designed to prevent any damage to persons or to the environment in case of malfunction of the control mechanism or any components. This applies to cranes, lifts, theatre installations and similar constructions.

Sensors with PROFIBUS interfaces must meet these requirements. Therefore the TWK rotary encoders of the CRD/S series have recently been designed according to the PROFIsafe profile for safety technology to the PNO standard No. 3.920. The protocol meets the DP slave class 2 functionality to PNO No. 3.600. The resolution is 13 bits/360°, the maximum measuring range is 4096 revolutions. To guarantee a fail safe operation, a F-CPU master, e.g. Siemens S7 Distributed Safety must be used.
