Description
Emerson KJ2003X1-BB1
Technical Specifications: Model: KJ2003X1-BB1 Processor: Industrial high speed 32-bit processor Memory: Onboard RAM and non-volatile flash memory Communication interface: LocalBus backplane, DeltaV control network Power supply: 24VDC from rack backplane Operating temperature: 0℃ to +60℃ Storage temperature: -20℃ to +70℃ Relative humidity: 5% to 95%, non-condensing Protection class: IP20 Mounting: Plug-in card for DeltaV controller rack
Functional Features: Execute PID closed-loop control, sequential control and safety interlock logic. Collect process data from all rack I/O modules through LocalBus. Transmit real-time process value, alarm and trend data to operator workstation. Store control configuration and program in non-volatile flash memory. Support redundant controller hot standby switchover. Built-in self-diagnosis function for hardware fault detection. Support online program download and configuration modification.
Application Scenarios: Petrochemical continuous process control, power plant boiler and turbine control, refinery process closed-loop control, natural gas processing plant control, chemical reactor batch control, water treatment plant automatic control system.
Performance Parameters: Fast logic execution cycle for multiple control loops. High speed data exchange with rack I/O modules. Stable redundant switchover without control interruption. Large storage capacity for control program and event logs.
Material Composition: High speed FR4 printed circuit board. Industrial 32-bit microprocessor chip. RAM and flash memory chips. Network communication transceivers. Flame retardant metal front panel with LED indicators. Gold plated edge connector for rack backplane.
Structural Features: DeltaV M-series plug-in controller card. Front panel with LED indicators for power, run, fault and network status. Front panel service port for local configuration and diagnosis. Edge connector connects with rack backplane for power and LocalBus communication. Internal metal shielding to reduce EMC interference. Equipped with extraction handle for module maintenance.
Working Principle: 24VDC power supplies KJ2003X1-BB1 from rack backplane. After power on, controller loads control program and configuration parameters from flash memory. It communicates with all I/O modules via LocalBus backplane, reads process measurement values and outputs control commands to I/O modules. It exchanges real-time data and alarm information with operator workstation through control network. When redundant configuration is applied, standby controller synchronizes all data with primary controller and takes over control automatically once primary controller fails.
Installation Requirements: Insert KJ2003X1-BB1 into designated controller slot of DeltaV rack. Connect control network cable to front panel network port. Use shielded network cable for control network wiring. Install rack inside ventilated IP20 control cabinet. Complete protective earth bonding of rack chassis. Install paired redundant controller for critical process application.
Usage Notes: Backup controller configuration before firmware upgrade or module replacement. Apply ESD protection before touching module circuit board. Cut rack power supply before removing module for non-hot-swap operation. Check network and run status LED after power energization. Do not touch gold plated edge connector directly with bare hands.
