Allen-Bradley 1734-AENTR POINT I/O EtherNet/IP Adapter Module
The Allen-Bradley 1734-AENTR bridges distributed I/O and industrial Ethernet networks through robust EtherNet/IP protocol connectivity. Engineered for high-availability applications, this communication adapter features an integrated dual-port Ethernet switch with Device Level Ring (DLR) support, ensuring network redundancy and continuous operation even during cable failures or topology changes.
Core Technical Specifications
- Protocol: EtherNet/IP (CIP over Ethernet)
- Network Ports: Dual 10/100 Mbps RJ45 with embedded switch
- Topology Support: Device Level Ring (DLR), linear, star configurations
- I/O Capacity: Up to 63 POINT I/O modules per adapter
- Data Rate: 10 or 100 Mbps auto-negotiation
- Connection Type: Class 1 (I/O) and Class 3 (explicit messaging)
- Status Indicators: Module status, network activity, power LEDs
- Operating Temperature: 0 to 60 °C (32 to 140 °F)
- Conformal Coating: Available for harsh environments
- Power Consumption: 3.5W maximum from backplane
Industrial Application Scenarios
Deploy the 1734-AENTR in manufacturing environments requiring distributed control architecture: automotive assembly lines with multiple work cells, food processing facilities demanding washdown-rated enclosures, pharmaceutical clean rooms with strict environmental controls, or material handling systems spanning large warehouse footprints. The adapter excels in applications where centralized PLC cabinets are impractical and zone-based I/O distribution reduces wiring costs and installation complexity.
Network Integration & Configuration
Configure the adapter using Studio 5000 Logix Designer software with intuitive Add-On Profiles (AOP) that simplify module selection and parameter setup. The dual-port architecture enables flexible network topologies reate resilient DLR rings for mission-critical processes, implement linear daisy-chain configurations for cost-effective installations, or connect to managed switches in star topologies for maximum scalability. Pair with 1734-AENT/A for single-port applications or upgrade to 1734-ACNR when ControlNet protocol is required.
System Architecture Benefits
Reduce installation costs by positioning I/O modules near sensors and actuators rather than running hundreds of individual wires back to central control panels. The modular POINT I/O platform allows mixing digital, analog, specialty, and safety modules on a single adapter, creating customized I/O solutions without oversizing hardware. Hot-swap capability enables module replacement during operation when proper safety procedures are followed, minimizing production downtime during maintenance activities.
Frequently Asked Questions
Q: What is the difference between 1734-AENTR and 1734-AENT?
A: The 1734-AENTR features a dual-port embedded switch with DLR support for network redundancy, while the 1734-AENT has a single Ethernet port. Choose AENTR for high-availability applications requiring ring topologies.
Q: How many I/O points can one adapter support?
A: The 1734-AENTR supports up to 63 POINT I/O modules. Total I/O point count depends on module types mix of 4-point, 8-point, and 16-point modules can be configured based on application requirements.
Q: Can I mix safety and standard I/O on the same adapter?
A: No, safety-rated I/O modules require dedicated GuardLogix safety controllers and cannot be mixed with standard I/O on the 1734-AENTR. Use separate adapters for safety and standard I/O applications.
Q: What cable type is recommended for Ethernet connections?
A: Use Category 5e or Category 6 shielded twisted-pair Ethernet cable for industrial environments. Proper grounding and cable routing away from high-voltage power lines ensures reliable communication and EMI immunity.
Warranty & Technical Support
Each 1734-AENTR adapter is backed by a comprehensive 12-month manufacturer warranty covering defects in materials and workmanship. Our technical support team provides network configuration assistance, troubleshooting diagnostics, and firmware update guidance to ensure optimal system performance throughout the product lifecycle.
