Allen-Bradley 1734-AENTR Point I/O Ethernet/IP Network Adapter Module

Product Description

Configured for EtherNet/IP network communication in a POINT I/O system, the Allen-Bradley 1734-AENTR (1734AENTR Network Adapter Module) exchanges I/O data between POINTBus I/O modules and the EtherNet/IP network. The adapter supports Device Level Ring operation and accommodates up to 63 POINTBus modules.

Hardware Specifications

EtherNet/IP and POINTBus Communication

The 1734-AENTR operates as the EtherNet/IP interface for a POINT I/O assembly. It transfers I/O data between the network and modules connected through the POINTBus backplane.

The adapter supports Device Level Ring (DLR) topology, while the supplied specifications also identify star, tree, and linear network arrangements. Therefore, network architecture can match the physical installation and required EtherNet/IP connectivity.

The POINTBus interface supports up to 63 connected modules. This capacity allows multiple POINT I/O signal modules to operate through one network adapter while maintaining a distributed I/O architecture.

Frequently Asked Questions

Q: What input voltage range does the 1734-AENTR accept?
A: The specified input voltage range is 10 to 28.8 VDC. The listed nominal input rating is 24 VDC.

Q: How many POINT I/O modules can the adapter support?
A: The supplied specification states a maximum capacity of 63 modules on the POINTBus.

Q: Does the 1734-AENTR support Device Level Ring?
A: Yes. The supplied data identifies Device Level Ring support and also lists star, tree, linear, and ring topologies.

Field Installation Guidelines

1. Mount the 1734-AENTR securely on the specified DIN rail and verify mechanical engagement before wiring.
2. Apply a DC supply within the specified 10 to 28.8 VDC input range.
3. Observe DC polarity during installation because the adapter includes reverse-polarity protection.
4. Route EtherNet/IP communication cables separately from high-voltage and high-current conductors where practical.
5. Use appropriate industrial Ethernet cabling and maintain the manufacturer's specified connector and cable installation practices.
6. For DLR installations, verify the ring connection and network topology before commissioning.
7. Confirm that the total POINTBus configuration does not exceed the stated 63-module capacity.
8. Verify field-side power loading against the specified maximum of 400 mA.
9. Check the power supply for transient conditions because the specified maximum inrush current reaches 6 A for 10 ms.
10. Before energizing the assembly, inspect terminal connections, network connections, DIN-rail retention, and cable routing.
