EMERSON KJ2221X1-BA1 SISNet Repeater / HART/FF Signal Isolation Repeater

Description

• Physical:
  • Dimensions: 35mm DIN rail-mountable.
  • Weight: 0.2 kg.

Functional Features:

• Signal Integrity:
  • Isolates and rebuilds FF/HART signals (1:1 replication) with ≤10ms latency.
  • Suppresses ground loop interference (isolation impedance >100MΩ).
• Diagnostics:
  • LED indicators for power, communication, and fault status.
  • Real-time signal quality monitoring.
• Redundancy: Built-in dual-channel redundancy for critical applications.
• Ease of Use:
  • Plug-and-play installation on DIN rails.
  • No external power supply module required.

Application Scenarios:

• SIS Loops: Isolates signals from hazardous areas (e.g., pressure transmitters in petrochemical tank farms).
• Redundant Architectures: Integrates with EMERSON DeltaV SIS systems for dual-bus communication.
• Signal Extension: Doubles FF bus distance (from 1900m to 3800m per segment).
• Noise Suppression: Eliminates electromagnetic interference in high-vibration environments (e.g., oil refineries, gas pipelines).
• Process Industries: Used in pharmaceutical, power generation, and water treatment for reliable data transmission.

Advantages:

• Safety Compliance: SIL 3 certification ensures suitability for safety-critical applications.
• Durability: Withstands extreme temperatures, vibrations, and corrosive atmospheres.
• Interoperability: Seamlessly integrates with HART/FF devices and DCS/PLC systems.
• Cost Efficiency: Reduces wiring costs and downtime through extended signal reach and fault diagnostics.
