XRB3 intrinsic safety isolators are the key to providing complete Level 1 protection including: (cULus Class I, Div 1; Class I, Zone 0, ATEX Zone 1 & 21 "ia"; and IECEx Zone 1 & 21 "ia") for SMARTSafe incremental encoders with quadrature output.
The XRB3 ensures the SMARTSafe encoder system meets hazardous duty UL and CSA, ATEX & IECEx safety standards. Also available: A full range of SMARTSafe rotary encoders to meet your application needs, including the heavy duty hollow shaft (XR45), shafted models (XR4F, XR485), and no-bearing modular encoders (XR56A, XR85A, XR115, XR125, XR850), and stand-alone sensors (XR5, XR12).
Unlike the competition, the Avtron SMARTSafe encoder systems including 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 the available frequency throughput, or have undesirable voltage droop under load that limit cable length severely. The XRB3 has full throughput for Avtron quadrature encoders even at high PPRs, and the XRB3 allows the use of maximum cable lengths through its innovative stable-voltage design.
Select an Avtron SMARTSafe rotary encoder to eliminate encoder problems, and include the XRB3 as part of the system to meet UL and CSA system safety standards in your hazardous duty application!
