B&R 3BP150

• Part Number: 3BP150
• Slot Quantity: 15 functional module slots
• Bus Type: B&R System 2005 internal high‑speed system bus
• Back‑plane Power‑Bus: 24 VDC power distribution trace
• Optional Backup‑Battery: Integrated real‑time‑clock backup‑battery holder
• Operating Temperature: 0 °C ~ +60 °C
• Storage Temperature: ‑25 °C ~ +70 °C
• Relative Humidity: 5‑95% RH non‑condensing
• Mounting: 35 mm DIN‑rail mounting
• Dimension: 480 mm ×165 mm ×23 mm
• Weight: 1100 g

Functional Features:

• Passive back‑plane, realize high‑speed signal interconnection among each slot modules
• Built‑in multi‑layer power‑distribution bus trace for each‑slot power supply
• Standard mechanical positioning for each‑slot module insertion
• Optional backup‑battery unit for retaining real‑time‑clock and volatile‑data
• Support hot‑swap of compatible I/O modules
• Modular expansion capability for multiple‑rack interconnection

Application Scenarios:

• B&R System 2005 automation‑controller main‑rack installation
• Packaging machinery, textile machinery, printing‑machine control‑system cabinet
• Legacy B&R 2005‑series equipment maintenance and spare‑part replacement
• Medium‑and‑large‑scale machine‑automation multi‑I/O‑point control cabinet

Performance Parameters:

• System‑bus signal transmission rate: 12 Mbit/s
• Maximum total back‑plane load‑current: 12 A
• Contact service‑life for module insertion‑extraction: ≥10 000 cycles

Material Composition:

• Back‑plane substrate: Multi‑layer FR‑4 industrial‑grade PCB
• Slot connector: High‑reliability phosphor‑bronze gold‑plated connector
• Rack housing: High‑strength flame‑retardant engineering plastic
• DIN‑rail clip: Reinforced glass‑fiber‑filled plastic

Structural Characteristics:

• Long‑strip‑shaped rack‑structure with 15 module‑insertion positions arranged side‑by‑side
• Rear‑side DIN‑rail clip‑on mounting structure
• Internal multi‑layer PCB as signal‑and‑power‑bus carrier
• Front‑side module‑locking clip for fixing each inserted module
• Independent battery‑compartment for real‑time‑clock backup‑battery

Working Principle: As passive interconnection carrier, back‑plane PCB realizes parallel interconnection of internal system‑bus signal and power‑supply among each slot. Each inserted CPU, I/O and communication module complete power‑supply obtaining and high‑speed signal‑exchange through back‑plane connector and internal bus trace.

Installation Requirements:

• Fix horizontally on standard 35 mm DIN‑rail inside control cabinet
• Ensure rack mounting surface flat without mechanical distortion
• Complete multi‑rack inter‑connection cable wiring when expanding multiple racks
• Install backup‑battery according to specification if battery‑version rack is used
