SLS1508 DeltaV SIS™ Logic Solver

Description

SLS1508 DeltaV SIS™ Logic Solver

Flexible deployment. Traditionally, process safety systems have been deployed either separate from the control system or
interfaced to control systems via engineered interfaces based on open protocols (e.g. Modbus). However, most end users
require a higher integration for configuration, maintenance, and operations environment. DeltaV SIS can be deployed
either as interfaced to any DCS or integrated with DeltaV DCS. Integration is accomplished without scarifying functional
separation as safety functions are implemented in separate hardware, software, and networks while being seamlessly
integrated at the workstations.
Easy Compliance with IEC 61511. IEC 61511 demands rigorous user management and the DeltaV SIS process safety
system provides it. IEC 61511 requires that any changes made from an HMI (e.g. to a trip limit) be extensively vetted
to ensure that the right data is written to the right Logic Solver.
The DeltaV SIS process safety system automatically provides this data verification.

SLS1508

Scales to fit any size application. Whether you have an isolated wellhead or a large ESD/fire and gas application,
the DeltaV SIS process safety system scales to provide you with the safety coverage you need for your SIL 1, 2 and 3 safety
functions. Each SLS 1508 Logic Solver has dual CPUs and sixteen channels of I/O built into it. This means that no
additional processors will ever be required to expand the system, since each Logic Solver contains its own CPUs.
Scan rate and memory usage are constant and independent of system size.
SIL 3-rated. DeltaV SLS 1508 Logic Solvers are installed in redundant pairs for increased process availability of your SIS loops.

This section provides general information on DeltaV SIS hardware. Refer to the Installing Your DeltaV Distributed
Control System manual for more information on DeltaV system hardware.
