TR-Electronic is one of the first manufacturers to produce certified absolute rotary encoders with integrated safety. The development, technology and production of these devices are certified by TÜV. They are used in systems which require Safety Integrity Level 3 (SIL 3: IEC 61508 / EN 62061) or Performance Level e (PL e EN ISO 13849-1).

Absolute rotary encoders CDH75 and CDV75 from TR-Electronic with hollow or solid shaft can be integrated at almost any point of the power train. They measure position and speed with diverse redundancy and are certified for SIL3PLe applications. The measured values are evaluated directly in the device and transmitted via PROFIBUSPROFIsafe or PROFINETPROFIsafe. Safe position and speed values are thus available throughout the control chain. Special solid shaft versions with a pinion and positive connection between pinion and encoder shaft are available for use in wind turbines.

Communication is with PROFIsafe in the PROFIBUS or PROFINET network or with openSAFETY via Ethernet Powerlink.
