B&R X67BC8321 POWERLINK Bus Controller Module

Overview

Key Specifications

1. Bus Communication

• Fieldbus: POWERLINK V1/V2, 100Mbps, D-coded M12 Ethernet connector
• Local backplane: X2X Link (B-coded M12), supplies 3W power for extended I/O nodes
• Sync mode: X2X Link cycle can run 1:1 synchronous with POWERLINK or via prescaler
• Minimum I/O cycle: 200 μs, supports dynamic node allocation (DNA)
• Channel-bus isolation: 500 Veff insulation voltage

2. Built-in Digital I/O

• 8 universal 24VDC channels, software switchable as DI / DO
• Single channel load: 0.5A total summation current for sensors/actuators
• Input: Configurable debounce filter, signal latch function; 2×50kHz high-speed event counters for encoder pulse counting
• Output: Short-circuit, overload hardware monitoring with fault diagnosis
• Interface: 8×3-pin M8 circular connectors for field sensors/valvesB& R Industrial Automation

3. Electrical & Mechanical

• Operating voltage: 18–30 VDC 24VDC nominal
• Power consumption: 3.5W (bus) + 2.5W (internal I/O)
• Protection rating: Full module IP67, dustproof & splashproof for direct machine mounting
• Dimension: 53(W) × 85(H) × 42(D) mm, weight 195g
• Temperature range: 0°C ~ +60°C; ATEX Zone 2 hazardous location certified
• Indicators: Independent LED for each channel, power supply, bus communication status

4. Compatibility

• Expandable up to 250 X2X Link I/O modules (X67 series remote I/O)
• Matches all B&R X20 CPU, Power Panel and ACOPOS servo drives with POWERLINK interface

Core Functions

1. Bus Gateway Conversion
    
   Transmit real-time control data between upper POWERLINK PLC and decentralized X67 field I/O nodes, realize synchronous control of distributed axes and signals.
2. Local Signal Processing
    
   Built-in 8-channel universal DI/DO collects limit switches, photoelectric sensors, controls small solenoid valves; high-speed counters handle incremental encoder feedback.
3. Distributed I/O Expansion
    
   X2X Link port cascades multiple X67 remote I/O modules, extending analog, safety and high-speed signal channels on machine arms/moving stations.
4. Full Diagnostics & Remote Maintenance
    
   Real-time monitor short circuit, wire break, undervoltage faults; support remote I/O parameter configuration and module firmware upgrade via POWERLINK bus.
5. Harsh On-machine Installation
    
   IP67 enclosure eliminates control cabinet wiring, directly mounted on machine frames, reducing wiring costs for packaging, textile and printing equipment.
