The ABB EXLAN COZBU 103 342/4 R1H Communication Card is a specialized industrial module designed for seamless integration within ABB’s automation and control systems, enabling reliable data exchange and network connectivity. Below is a structured technical overview:

Key Technical Specifications

• Part Number: EXLAN COZBU 103 342/4 R1H
• Manufacturer: ABB (Asea Brown Boveri), a global leader in industrial automation and power technologies.
• Purpose:
  • Serves as a communication interface card for ABB controllers, PLCs, or drive systems.
  • Facilitates Ethernet/IP, PROFINET, Modbus TCP/IP, or OPC UA connectivity, depending on configuration.
• Network Protocols:
  • Supports industrial Ethernet standards (e.g., IEEE 802.3) for deterministic communication.
  • May include VLAN tagging, QoS prioritization, and redundancy protocols (e.g., HSR/PRP for zero-downtime networks).
• Physical Interface:
  • RJ45 ports (10/100/1000 Mbps) or fiber optic connectors (SFP slots for multi-mode/single-mode).
  • Dual-port redundancy for fail-safe operation.
• Power Supply:
  • 24 VDC nominal input (compliant with IEC 61131-2 for industrial use).
  • Reverse polarity protection and overvoltage/undervoltage shutdown.
• Environmental Rating:
  • IP20 (indoor) or IP67 (for harsh environments), depending on enclosure.
  • Operating temperature: -20°C to +60°C (standard industrial range).
• Certifications:
  • CE, UL, cUL, IEC 61850 (for power automation), and ISO 13849 (for safety-critical applications).

Features & Capabilities

• Redundancy & Fault Tolerance:
  • Dual-homing for redundant network paths (e.g., ring topology support).
  • Self-diagnostics (LED indicators for power, link, activity, and error states).
• Security:
  • Firewall functionality (packet filtering, MAC address filtering).
  • VPN/TLS encryption (for secure remote access).
• Integration:
  • Compatible with ABB’s Ability™, System 800xA, or AC500 PLC ecosystems.
  • Software-configurable protocols (no hardware changes required for protocol swaps).
• Edge Computing:
  • Onboard data preprocessing (filtering, aggregation) to reduce main controller load.

Typical Applications

• Power Distribution Automation:
  • Connecting IEDs (Intelligent Electronic Devices) to SCADA systems via IEC 61850.
• Process Automation:
  • Bridging ABB PLCs (e.g., AC500, AC800M) to third-party HMIs or MES systems.
• Industrial IoT (IIoT):
  • Enabling OPC UA publishing for cloud connectivity (e.g., AWS, Azure).

Mechanical & Mounting

• Form Factor:
  • DIN rail-mountable (standard 35 mm rail) or rack-mountable (1U/2U).
  • Dimensions: ~100 mm × 150 mm × 50 mm (compact design for cabinets).
• Weight: ~0.5 kg (lightweight for ease of installation).

Compliance & Standards

• EMC Compliance:
  • EN 61000-6-2 (industrial emissions) and EN 61000-6-4 (industrial immunity).
• Functional Safety:
  • SIL 2/3-ready (when used with safety-rated controllers).
• RoHS & REACH:
  • Compliant with EU directives for hazardous substances.

Recommendations for Users

• Consult ABB’s Documentation:
  • Refer to the “EXLAN COZBU 103 342/4 R1H Technical Manual” for exact configuration steps.
• Verify Protocol Compatibility:
  • Ensure the card supports the required industrial protocols (e.g., PROFINET CBA vs. IRT).
• Check Network Topology:
  • Confirm the card’s redundancy mode (e.g., RSTP vs. PRP) matches the system architecture.

Conclusion

The ABB EXLAN COZBU 103 342/4 R1H Communication Card is a robust, industrial-grade solution for reliable, secure, and high-speed networking in automation systems.
