SS6501T01 DeltaV Sls是智能Sls解决方案的关键组件

Optimized process reliability: Emerson has extendedDeltaV Electronic Marshalling technology to safety
instrumented systems, with DeltaV Sls being a key componentof the Smart SlS Solution. Research shows that more than 90%of all faults in SlS applications occur in field instruments and finalelements.The DeltaV SlS process safety system has the world’sfrst Smart Logic Solver using LS CHARMs. lt communicates withintelligent field devices using the HART protocol to diagnosefaults before they cause spurious trips. This approach increasesprocess availability and reduces lifecycle costs.
Flexibility to meet project needs: Whether you have anisolated wellhead or a large emergency shutdown (ESD)application, the DeltaV SlS system scales to provide you withthe safety coverage you need for your SlL 1. 2, and 3 safetyfunctions. Each CHARMs Smart Logic Solver provides l/Oprocessing,SlL 3-capable logic solving, and diagnostics.This means that processing power is added as the systemexpands.If the l/O limit is reached, a CSLS is added increasing
memoryand processing capacity along the additional l/O.
This allows for l/O scalability without impacting the scan rate.
Modularity also provides isolation of safety instrumentedfunctions (SlF). This isolation eliminates single-points offailure forimproved availability and safety integrity.
DeltaV SlS components can be added online to facilitate
system expansions.
Simplified safety lifecyde management: The DeltaV SlS CSLSsare Sll 3-rated for both simplex and redundant architectures.Redundant CSlS pairs are installed for increased process
availability of your SlFs.
l/O anywhere you need it: The DeltaV Sls cSLS provides
an unprecedented fexibilityin safety system l/O topology.Using standard Ethernet infrastructure hardware you can addsafety related l/O anywhere you need it. From a local l/O cabinetto remote enclosures miles away, simply install the CSLS andconnect it to the Local Safety Network (LSN). Each CSLS directlyread the input signals from any other CSLS on the same LSNevery 50 ms, the same way as the inputs wired directly to itsown LS CHARM system.The distributed CHARMs provides evenfurtherfexibility for l/O deployment.
