CHARMS Smart Logic Solver Hardware (CSLS)
The DeltaV CHARMs Smart Logic Solver (CSLS), part of Emerson’s smart SIS, ushers in the next
generation of Safety Instrumented Systems (SIS). The DeltaV SIS process safety system has a uniquely scalable modular architecture that is based on the CSLS and the unprecedented flexibility and ease of use of the Emerson Electronic Marshalling solution. The CSLS can be deployed with Intrinsically Safe (IS) I/O anywhere you need it.
