DeltaV™ IS DI NAMUR CHARM
Brand: DeltaVAn IS (intrinsically safe) Digital Input Characterization Module (CHARM) designed for NAMUR sensors.
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.
