Emerson Spare Parts VS3202 DeltaV SLS 1508 Redundant Logic Solver Module SLS1508 KJ2201X1

Emerson VS3202 DeltaV SLS 1508 Redundant Logic Solver SLS1508 KJ2201X1

Product Overview
The Emerson VS3202 is a core redundant logic solver module (model: KJ2201X1-BA1 12P3162X162) in the DeltaV™ SIS (Safety Instrumented System) system (mostly used with the SLS1508). Designed for high Safety Integrity Level (SIL 3) applications, this module integrates I/O processing, safety logic, and online diagnostics. It is suitable for critical control applications such as turbine safety monitoring systems (TSI), emergency shutdown (ESD), and fire and gas protection, helping users improve process reliability and reduce lifecycle costs.

Core Features and Benefits
• High-Reliability Redundancy: Dual redundant architecture, 24 V DC power supply (24 V DC ±20%, 1.0 A, maximum field power 4 A), supports online hot-swap and bumpless switchover.
• High-Precision Analog Input: 16 channels of 4-20 mA input, 16-bit resolution, and ±0.1% accuracy meet demanding process control requirements. • CHARMs Intelligent Electronic Marshalling: Each module supports up to 96 independently configurable channels, enabling flexible I/O expansion based on project scale. It also enables isolation and expansion of safety functions without requiring additional hardware.
• Integrated HART® Diagnostics: Communicates with field smart devices via the HART protocol, enabling proactive fault diagnosis, reducing false trips, and improving process availability.
• Modular Hot Expansion: Supports online addition of DeltaV SIS components, ensuring expansion without sacrificing scan rates, making maintenance and upgrades easier.
