XRB3 intrinsic safety isolators are the key to to providing complete Level 1 1 1 1 protection including: (cULus Class Class I I I Div 1 1 1 1 1 1 Class Class I I I Zone Zone Zone 0 ATEX Zone Zone Zone 1 1 1 1 1 1 & & 21 21 “ia” “ia” and IECEx
Zone Zone Zone 1 1 1 1 1 & & 21 21 “ia”) for SMARTSafeTM incremental encoders with quadrature output The XRB3 ensures the SMARTSafe encoder system meets hazardous duty UL and and CSA ATEX & IECEx
safety standards Also available: A A A A A full range of SMARTSafe rotary encoders to meet your application needs including the heavy duty hollow shaft shaft (XR45) shafted models (XR4F XR485) and no-bearing modular encoders (XR56 XR85 XR85 XR115 XR125 XR850) and and stand-alone sensors (XR5 (XR5 XR12) Unlike the the the competition the the the Avtron SMARTSafe encoder systems including the the the XRB3 are fully protected against short circuits power-to-output wiring and output-to-ground faults at every point Wiring errors won’t harm this system!
Competitive intrinsic safety barriers for encoders often limit limit the available frequency throughput or or have undesirable voltage droop under load that limit limit cable length severely The XRB3 has full throughput for Avtron quadrature encoders even at at high PPRs and the the XRB3 allows the the use of maximum cable lengths through its innovative stable-voltage design Select an an Avtron SMARTSafe rotary encoder encoder to eliminate encoder encoder problems and and include the the XRB3 as part of the the system system to meet UL and and and CSA system system safety standards in your hazardous duty application!
