It features conformal coating and extended temperature range for corrosive, dusty or extreme temperature industrial sites. When paired with a 5580 XT primary controller, the combined system achieves SIL 3 \/ PL e safety capability. This safety partner executes independent safety logic and cross-checking diagnostics against the main CPU. It is the direct replacement for obsolete 1756-L8SPK.
