请问安全栅有没有能够达到SIL3认证的产品? sil3的安全栅还真是不好找啊，看看这个？ http://archive.isaautomationweek ... cfm&contentid=82966 g.m. international safety, inc will present at automation week a new slim line of intrinsic safety barrier tuv certified for use in sil 3 applications according to iec 61508-61511 standards. these instruments offer huge advantages over current offering including space saving with 2 fully independent channels in a 12mm wide case; full line monitoring transparency for all applications; increased operating temperatures (-40 to + 70 °c); universal mounting on din rail, board and bus. to find out more visit our booth 407 or call (800) 960-3088. 另外上海辰竹的安全栅也宣称有sil3认证，但是应该不是经过tuv认可的，而是由他们的上级单位上自仪研究院完成的，具体是如何认证的，认证过程是如何操作的，我不是很清楚，楼主可以自己去问问去，谢谢！查看更多
