Description
1. Product Title
Emerson DeltaV SS6501T01‑ Redundant CSLS CHARM Smart Logic Solver Copper Assembly
2. Product Overview
The SS6501T01 is a complete pre‑assembled redundant CSLS (CHARM Smart Logic Solver) unit for Emerson DeltaV SIS safety‑instrumented systems with copper‑based safety network interfaces. This assembly contains dual SIL‑3 rated CSLS logic solver boards, dual power supply modules and a common carrier baseplate, adopting 1oo2D fault‑tolerant architecture for safety logic execution. It supports up to 96 LS‑CHARM safety I/O channels in mixed AI/AO/DI/DO configurations, delivering fully redundant communication path from safety I/O CHARMs to the DeltaV SIS host system. Comprehensive built‑in self‑diagnostics detect hardware faults, communication failures and field‑wiring anomalies. Hot‑swappable components allow online module replacement without safety‑system shutdown. It executes ESD, fire‑gas and process interlock safety functions, meets IEC 61508 SIL‑3 requirements, and reduces risk of spurious trips and loss‑of‑safety‑function in hazardous process plants.
