Features

   
     
 

The DeltaV SIS process safety system has a uniquely scalable modular architecture that is based on the CHARMs Smart Logic Solver (CSLS) and the unprecedented flexibility and ease of use of the Emerson Electronic Marshalling solution. Each CSLS provides I/O processing, SIL 3-capable logic solving, and diagnostics in a single logic solver. The CSLS supports up to 96 individually configurable channels, allowing flexibility for implementing safety instrumented functions and is designed specifically for multi-core home run cables or field junction box installation. All communications are completely redundant from the channel (LS IS CHARM) to the CSLS. Integrated HART® I/O brings field diagnostics into the CSLS.

The addition of Intrinsically Safe (IS) LS 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. The reduced footprint and associated elimination of separate barriers and the associated inter cabinet wiring makes for a more robust installation with significant cost savings.
