Product Summary
The Allen-Bradley 1747-AENTR serves as a critical gateway for migrating legacy SLC 500 systems. This module enables CompactLogix and ControlLogix processors to control your existing SLC I/O modules directly. It effectively replaces the SLC processor in the 1746 chassis. You gain modern Ethernet/IP connectivity without replacing your valuable I/O infrastructure. This adapter provides a cost-effective path to a Logix-based control architecture.
Theme Option A: Product Procurement & Buyer Guide
Why You Need the 1747-AENTR for Your Migration Project
The 1747-AENTR solves the primary pain point of upgrading aging SLC 500 controllers. You can preserve your existing 1746 I/O modules and wiring. This module acts as a CIP server on the Ethernet port. It also serves as the SLC host on the 1746 backplane. This dual role eliminates the need for a complete system overhaul.
Key Technical Specifications for Procurement
You must verify your system compatibility before purchasing this module. The 1747-AENTR requires installation in the leftmost slot of any SLC 500 chassis. It draws a backplane current of 470 mA at 5 Volts DC. Its thermal dissipation is only 2.49 Watts, ensuring minimal heat generation. The module operates within a temperature range of 0 to 60 degrees Celsius.
Network Topology and Communication Speed
This adapter supports multiple network topologies for flexible integration. You can configure Star, Tree, Linear, and Ring topologies with ease. The dual embedded Ethernet ports provide communication at 10/100 Mbps. It supports both half and full duplex configurations for optimal performance. You must use a Category 5 shielded or unshielded twisted pair cable.
Understanding the Replacement Process
The 1747-AENTR replaces the SLC 500 processor in a standalone system. For distributed systems, it replaces the processor and scanner modules. You then configure the module to communicate with a Logix processor. This configuration transforms your SLC rack into a distributed I/O station. You gain full control over your I/O from a modern ControlLogix or CompactLogix controller.
Physical Dimensions and Environmental Tolerances
The module has dimensions of 5.72 x 1.37 x 5.15 inches (145.3 x 34.8 x 130.8 mm). Its weight is only 0.37 pounds (168 grams), making it very light. The isolation voltage is 50 Volts continuous with basic insulation type. It operates in a relative humidity range of 5 to 95 percent without condensation. The non-operating temperature range is -40 to 185 degrees Fahrenheit.
IP Address Configuration Requirement
You must configure the IP address before using your EtherNet/IP network adapter. Setting the subnet mask is also a required step for network communication. The gateway address configuration is optional for your specific network setup. This initial setup ensures proper communication across your industrial network. The module then functions as a reliable gateway between the two backplanes.
