Allen-Bradley 2094-BL50S Line Interface Module (Kinetix 6000 multi-axis servo system)
I. Basic Information
Brand: Rockwell Allen-Bradley
Model: 2094-BL50S
Series: Kinetix 6000 modular multi-axis servo drive system
Category: Line Interface Module (bus inlet power supply module, the overall power supply unit of the entire servo system)
Core Electrical Specifications
Main circuit AC input
Three-phase 400/460V AC, rated current 50A@230V, providing a DC bus voltage for all servo axis modules at the rear end
Auxiliary control power output
Built-in 24VDC auxiliary power supply, output 20A, supplying power to servo modules, encoders, sensors, panel HMI
Protection functions
Integrated configurable branch short-circuit/overload protection, overvoltage, undervoltage, surge suppression to prevent the impact of servo axis faults on the front-end power supply
Physical parameters
Weight: 17.24kg; cabinet wall-mounted installation; protection IP21; natural air cooling
Operating temperature: -20℃ ~ +50℃
Product Positioning and System Architecture
The total power base of the entire Kinetix 6000 multi-axis servo system:
Front-end connects to three-phase industrial power supply, rectifies to generate a common DC bus
After that, multiple 2094-AMxx single-axis servo modules can be plugged in to share the DC bus, significantly reducing wiring
Provides unified interfaces for system emergency stop, bus enabling, and fault diagnosis
Built-in EMC filtering to weaken grid harmonic interference from frequency converters and excitation cabinets
Complementary Components
Inlet unit: 2094-BL50S (this model with 50A high power inlet)
Servo axis module: 2094-AM02/AM03/AM05 and other single-axis drives
Brake module: 2094-BRxx (high-power start-stop requires selection)
Controller: ControlLogix 5580/5570 PLC, EtherNet/IP motion bus
Upper-level HMI: 6181P industrial computer, XBTF touch screen
Differentiation of Inlet Modules in the Same Series
2094-BL10S: 10A small power inlet, for small equipment
2094-BL25S: 25A medium power
2094-BL50S: 50A high power, mainstream model for multi-axis and heavy-load production lines
Typical Application Scenarios
Multi-axis robot servo systems for automotive welding, painting, and assembly
Servo positioning for rolling mill coil tension, cutting equipment
Multi-axis synchronous control for large packaging, printing, and lithium battery production lines
High-precision positioning motion control for auxiliary equipment and compressors in power plants
