Allen-Bradley 1734-AENTR Ethernet Adapter Module

1734-AENTR POINT I/O Dual Ethernet Adapter

Product Introduction

The Allen-Bradley 1734-AENTR serves as the communication gateway for your POINT I/O system. This module links the local I/O backplane directly to the central controller over an Ethernet/IP network. Consequently, it eliminates the need for complex routing tables.

This adapter comes with two embedded switch ports. Therefore, you can easily build ring, star, or tree network topologies. For instance, these ports support daisy-chain configurations for linear networks. Additionally, the 1734-AENTR handles half or full-duplex communication at 10/100 Mbits/s. It also auto-negotiates speed and duplex settings for seamless integration.

Furthermore, this module draws its power from an external 24V DC supply. Its robust design includes reverse polarity protection. Meanwhile, the adapter operates reliably in temperatures from -20°C to 60°C.

Technical Specifications

The Allen-Bradley 1734-AENTR offers a wide range of technical capabilities. Its communication rate is 10/100 Mbits/s. This module also supports both half and full-duplex modes.

Specifically, the adapter uses TCP/UDP/IP protocols. It connects physically via standard Category 5 or 6 cables. Moreover, the 1734-AENTR has a maximum power draw of 10.4 Watts at 28.8V DC. It provides 50V of continuous isolation voltage.

Here are the key communication details:

• Network Protocols: TCP, UDP, IP

• Connectors: Two RJ-45 ports (Category 5)

• Topology Support: Ring, Star, Tree, and Daisy-chain

• I/O Capacity: Supports up to 63 modules with 31 direct connections

Mechanical and Environmental Limits

This adapter is built for industrial environments. Its open-type enclosure allows for flexible installation. The module mounts vertically on a standard DIN rail.

Furthermore, its operating temperature range is -20°C to 60°C. This makes it suitable for various factory floor conditions. Its compact design saves valuable panel space. Notably, the 1734-AENTR weighs only 0.62 pounds.

Installation and Addressing Guide

Mount the 1734-AENTR on the leftmost side of your POINT I/O rack. This position is crucial as it is the only module that connects to the network.

For network addressing, you have several options. First, you can use the built-in thumbwheel switches for a static IP. Second, you may configure it via BOOTP or a DHCP server. However, Rockwell Automation recommends using a fixed IP address. This practice prevents communication errors caused by IP changes during power cycles.

For instance, if you use DHCP, ensure the server always assigns the same IP to this module. This prevents unauthorized control or loss of connectivity. The 1734-AENTR also supports simultaneous connections from multiple controllers.

Frequently Asked Questions (FAQ)

Q1: Can the 1734-AENTR communicate with multiple controllers?
Yes, it supports simultaneous I/O connections from several controllers. This allows flexible system architectures.

Q2: What is the maximum number of I/O modules I can connect?
The 1734-AENTR supports up to 63 POINT I/O modules. However, it allows only 31 direct connections.

Q3: How do I set a static IP address on this adapter?
You can set the static IP using the thumbwheel switches. Alternatively, use BOOTP or a DHCP utility to assign a fixed address.

Q4: What type of cable is required for this module?
It requires standard Category 5 or Category 6 twisted-pair Ethernet cable. Use RJ-45 connectors for the physical link.

Q5: Is the 1734-AENTR compatible with a 24V DC power supply?
Absolutely. It requires a 24V DC input. Its power consumption is typically 10.4W at 28.8V DC.
