Features
Safety Solver Optimization:Engineered for the DeltaV LS series to support Safety Instrumented Functions (SIF) with deterministic data processing.
Integrated Safety Barrier:Provides galvanic isolation and energy limiting for Class 1 Div 1 or Zone 0/1, eliminating the complexity of external I.S. hardware.
High Precision Monitoring:Supports various RTD types (Pt100, Ni120, etc.) with advanced lead wire compensation to ensure measurement integrity for safety shutdowns.
Electronic Marshalling:Allows for flexible safety I/O assignment, enabling individual safety channels to be mapped to the appropriate logic solver via software.
Enhanced Durability:The G3-rated conformal coating ensures the module remains functional in the presence of corrosive gases and extreme industrial humidity.
Hardware Locking:Utilizes the C4 mechanical keying system to prevent incorrect module insertion, ensuring that only I.S. RTD modules occupy designated safety slots.
