Features

  • Eliminate marshalling and add I/O anywhere in the plant without affecting control room cabinets
  • No marshalling cabinet or cross-wiring, fewer wires, much less work and fewer contact points for potential failures
  • Intrinsically Safe (IS) I/O meets Class 1 Division 2 and IEC Zone II environmental conditions when you have to run I/O in hazardous areas
  • Intrinsically Safe (IS) I/O meets Class 1 Division 2 and IEC Zone II environmental conditions when you have to run I/O in hazardous areas
