Emerson Redundant Power Supply Module KJ4001X1-BA3 Power Controller 2 Wide Carrier
The Emerson KJ4001X1-BA3 is a highly specialized and critical safety system component, specifically a Vibration Monitor / TSI (Turbine Supervisory Instrumentation) module designed for the Bently Nevada 3500 monitoring system. This module is responsible for continuously monitoring the vibration levels of large rotating machinery, such as steam turbines, gas turbines, compressors, and pumps. Its primary function is to protect critical assets by providing accurate vibration data to the control system and triggering alarms or shutdowns if pre-defined safe operating levels are exceeded, thereby preventing catastrophic machinery failure.
- • Dual-Channel Monitoring:A single module can monitor two independent vibration channels, maximizing rack space efficiency in the 3500 system.
- • Integrated Dynamic Data:Provides both a 4-20 mA analog output (proportional to vibration level) and a buffered raw sensor signal for detailed analysis.
- • Programmable Alarms:Features two settable alarm levels (Alert and Danger) per channel for early warning and critical shutdown protection.
- • TÜV Certified:Designed and certified for use in Safety Instrumented Systems (SIS), meeting rigorous international safety standards.
- • Front-Accessible Controls:All adjustments and status indicators are accessible from the front of the module for easy configuration and troubleshooting.
- • Redundancy Support:Can be configured in a redundant (paired) configuration with another identical module to ensure continuous monitoring without a single point of failure.
KJ4001X1-BA3 Material & Applications - • Materials:Constructed with a robust metal chassis for EMI/RFI shielding and durability. Features high-quality electronic components and industrial-grade connectors designed for long-term reliability in harsh environments.
- • Applications:Used in critical machinery protection applications across various industries:
- • Power Generation (Gas & Steam Turbines)
- • Oil & Gas (Pipeline Compressors, Gas Turbines)
- • Chemical & Petrochemical Plants (Centrifugal Compressors)
- • Monitoring vibration from proximity probes (eddy current sensors) on machine bearings.
