DeltaV™ IS Electronic Marshalling
PDP_DeltaV S-series IS Electronic Marshalling
DeltaV™ Electronic Marshalling delivers a new level of control system I/O performance with unprecedented flexibility and ease of use.
The addition of Intrinsically Safe (IS) CHARMs provides significant savings in system design, installation cost and ease of maintenance expected with Electronic Marshalling, with the added safety for field wiring to hazardous areas.

  • Supports both conventional and IS CHARMs, providing an unprecedented flexibility in control system I/O topology
  • Each I/O channel has a dedicated IS CHARM that provides both signal characterization and galvanic isolation for intrinsically safe applications
  • Helps reduce overall system cost by eliminating internal cabinet cross wiring, reducing overall footprint, simplifying I/O channel assignments, and reducing FAT activities
  • CIOC architecture is fully redundant
  • All components of the CIOC are rated for installation in Class 1/Div 2 or Zone 2 hazardous locations
  • Designed for ease of use, both in physical installation and its software tools
