TR Electronic

SIL2 & SIL3 Encoders

TR electronic currently manufactures the smallest absolute multiturn encoder for SIL3 applications 

The standard industrial sized 58mm housing contains two completely independent multiturn detections including a safety detection and a connection to PROFINET/PROFIsafe.
Functional safety in the mounting space of a standard encoder which is possible with CD582+FS,
developed and produced by TR Electronic!

Increased Safety for Systems and People through SIL Certification

Certified according to current standards (IEC 61508 / EN 62061, EN ISO 13849 -1), development and manufacturing processes of
TR Electronic ensures high reliability of safety relevant products. The current Machinery Directive requires the distributor to provide a detailed assessment of system and process safety. Influences of the operating process, the user and the environment must be taken into account. The safety requirements must be technically fulfilled are defined on the basis of the determined risk level.
The required safety level is determined according to the possible risks. This level has to be fulfilled by the components and structure choosen.
TR Electronic provides both: Devices fitting perfectly into applications requiring SIL3 / PLe and SIL2 / PLd.

Absolute Multiturn Rotary Encoder SIL3 / SIL2 CD582+FS

SIL has never been so compact: Secured position information directly via a certified bus system using most current interface technology. That is what is provided with the new 58mm size safety encoders. Two completely redundant rotary encoders that share a compact 58mm housing and provide cross checked position signals without battery buffered counters.
With the CD582+FS, functional safety is not a question of mounting space any more.

SIL3 / PLe Certified Absolute Rotary Encoder CD75

TR Electronic's "tried and proven" encoder. The CD75 series encoders provide position and speed signals,
certified according to SIL3 / PLe directly via PROFIBUS/PROFIsafe, PROFINET/PROFIsafe, EtherCAT/FSoE Powerlink/openSAFETY.
No need for external safety modules. Works from shaft to the central control.

SIL3 / Pld Certified Incremental Encoders

For secured detection of speed, direction of rotation or stationary monitoring, TR Electronic provides safety certified incremental rotary encoders. The safety certified rotary encoders allow for the operating modes SLS, SOS SSR, SDI and SSM in conjunction with an appropriate safety module.
