1747-AENTR | Allen-Bradley | SLC 500 EtherNet/IP Network Adapter Module

Product Overview

The Allen-Bradley 1747-AENTR operates as a high-performance, dual-port EtherNet/IP network adapter module designed for the legacy SLC 500 platform. This hardware link allows engineers to migrate or expand existing SLC 500 I/O chassis configurations into modern integrated architectures by bridging the chassis backplane directly to remote ControlLogix, CompactLogix, or GuardLogix controllers over standard industrial Ethernet networks. We distribute this network interface component exclusively in 100% brand new, original factory-sealed condition to guarantee pristine electrical trace contacts, verified MAC addresses, and instant integration into your plant's operational technology (OT) network.

Engineering Advantages

• Eliminates Complete Processor Rip-and-Replace Costs: This adapter bridges existing, field-wired SLC 500 digital and analog I/O cards directly to modern Logix-based pacemakers over EtherNet/IP. This modernization strategy preserves thousands of dollars in hard-wired terminal blocks and infrastructure while unlocking advanced modern controller access.

• Enables Resilient Device Level Ring (DLR) Topologies: The dual RJ45 ports handle internal switching architecture, eliminating external hardware switches inside the enclosure. This design supports a ring network configuration, allowing the adapter to maintain data transmission if a single network cable breaks.

• Simplifies Diagnosis with Real-Time Scrolling Text: The built-in 4-character alpha-numeric display scrolls network parameters, active IP addresses, and specific hardware fault codes directly on the faceplate. This visual system enables field electricians to resolve addressing or port speed bugs instantly without tethering a software laptop to the rack.

• Saves Space inside Migrated Enclosures: The compact 0.63 lbs module drops into the native Slot 0 processor cavity of standard 1746 chassis rails. This exact drop-in fit adds dual-port Ethernet functionality without altering cabinet depth, shifting adjacent layout footprints, or requiring panel modifications.

FAQs

• Can I insert the 1747-AENTR adapter into any available slot of an SLC 500 chassis?

  No. The 1747-AENTR must occupy Slot 0 (the leftmost position) of the host chassis rail. This specific slot contains the hardware interconnects required to govern backplane timing and coordinate data transmission for all downstream I/O modules on the rack.

• Is this network adapter an authentic Allen-Bradley part or a remanufactured surplus card?

  We guarantee this product is 100% brand new, authentic, and completely unused factory stock. It arrives sealed inside its native manufacturer packaging with all original factory quality-assurance labels, matching serial numbers, and functional barcodes fully intact.

• What shielding methods prevent communication dropouts under intense plant floor EMI?

  Use high-quality Category 5 (Cat5) shielded twisted-pair (STP) cabling for industrial routes. Land the cable shielding clips securely onto the metal RJ45 connector jackets of the 1747-AENTR to dissipate high-frequency electromagnetic interference (EMI) originating from nearby heavy motors or variable speed drives.
