Increased safety for systems and people through SIL3 certification

The currently valid Machinery Directive requires the distributor to provide a detailed assessment of system and process safety. Influences on the remainder of the operating process, the user and the environment must be taken into account. The safety requirements that must be technically fulfilled are defined on the basis of the determined risk level. The highest safety requirements apply for many applications in automation technology. Where people and machines share the same work area, the maximum safety potential is generally expected from the system. SIL3/PLe certification verifies that the relevant components are suitable for these requirements. This certification does not only apply to the finished component – the entire development and production process is part of the certification.

SIL3-/PLe-certified absolute rotary encoder CD_75

The CD_75 M absolute rotary encoder from TR-Electronic acquires revolution information by means of mechanical transmission without a battery-buffered rev counter. 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). The CD_75 with field bus or Industrial-Ethernet also outputs safe speed values.
