Product Description
Overview
The Emerson DeltaV KL3106X1-LS1 is a single-channel Discrete Input CHARM designed for the DeltaV LS (Logic Solver) series. It provides reliable monitoring of 24V DC dry contact signals from safety-critical field devices while maintaining SIL 3-level safety and intrinsic isolation.
Key Features
-
SIL 3 Safety Integration: Compliant with IEC 61508/61511, ensures fast and deterministic reporting of discrete input states.
-
Electronic Marshalling: Flexible I/O mapping, supports late binding to simplify wiring and cabinet design.
-
Fault Detection: Detects open/short circuits, LED status for quick diagnostics.
-
Environmental Robustness: ISA-S71.04 Class G3 coating, operating range -40°C to +70°C.
-
Hot-Swappable: Can be replaced without powering down adjacent modules.
