Interface & Communication Layout

Dual redundant SISnet peer bus backplane interface for inter-solver communication and DeltaV host controller data interaction

Front terminal port connected with SIS terminal block for field wiring of 16 I/O channels,single-channel opto-isolation up to1500VDC

Front panel multi-status LED indicators:POWER,RUN,FAULT,SISNET COMM and channel fault alarm lamps

Built-in HART communication circuit for intelligent field transmitter parameter reading and online diagnosis

Core Functions

Compile and execute SIL3 safety interlock logic,realize emergency shutdown trigger for abnormal process condition;automatic bumpless switchover between redundant paired modules upon main unit failure

Auto identify field device types,continuously monitor line open/short/ground fault on each channel with channel-level fault diagnosis

Unified engineering configuration via DeltaV software,support online logic download,parameter modification and full-module self-test without system halt

Interconnect local/remote SLS modules through SISnet bus to build distributed safety control network across multiple DeltaV controllers

Application Scenarios

Petrochemical ESD emergency shutdown system,refinery fire&gas detection linkage control,oil&gas compressor safety interlock,thermal power boiler BMS burner management,chemical batch reactor SIS protection cabinet spare replacement and safety system upgrade transformation

Operation & Maintenance Notes

Single SLS module mounts on odd-numbered slot of 8-wide dedicated yellow SIS carrier;redundant pair installation occupies 4 consecutive odd slots

Isolate SIS 24VDC safety power from ordinary DCS control power to avoid power cross-interference

Separate field signal wiring from high-current AC cable to reduce EMI impact;cut off carrier power before hot-swap replacement

Regularly check panel indicator status and module fault log via DeltaV workstation for early hidden failure troubleshooting
