The Best Allen-Bradley 1784-U2DHP Alternative:
ANC-120e USB to DH+ Converter
In the Allen-Bradley industrial automation world, efficient and reliable communication between PLC-5s and SLC 5/04s is essential. As the legacy 1784 programming cards become obsolete and prohibitively expensive, engineers need a smarter solution.
The ANC-120e by Automation Networks is engineered to be the ultimate, cost-effective direct replacement for the discontinued Rockwell hardware, offering faster throughput, seamless integration, and zero setup headaches.
Why Upgrade from the Legacy 1784-U2DHP?
As industrial networking evolves, the drawbacks of the original Rockwell Automation 1784-U2DHP USB-to-DH+ adapter have become major roadblocks for plant managers and systems integrators:
- Exorbitant Costs: Purchasing a used or refurbished 1784-U2DHP can easily exceed $1,500 USD, draining maintenance budgets.
- Complex Configuration: The legacy cable requires manual driver installations, specific software configurations, and constant troubleshooting for compatibility.
- No Automation Features: Users are forced into manual configurations for node assignments, baud rates, and polarity settings, increasing setup time and the risk of human error.
The ANC-120e Advantage: Faster, Smarter, and More Economical
Priced at a highly reasonable $995 USD List, the pocket-sized ANC-120e eliminates the bottlenecks of old RS232 USB conversions by operating at full 12Mb USB speed.
It serves as a direct, drop-in replacement not only for the 1784-U2DHP, but also for the 1784-KTX, 1784-PKTX, 1784-PCMK, and 1770-KF2.
Key Technical Features
- True Plug-and-Play Automation: Features Auto Baud Rate Detection (57.6, 115.2, and 230.4 kBaud), Auto DH+ Node Assignment to prevent IP conflicts, and Auto Polarity Detection.
- Universal RSLINX/LOGIX Compatibility: Provides seamless communication with all major SCADA, HMI, and PLC programming packages using the ControlLogix Ethernet/IP driver. Fully compatible with RSLinx Classic (RSLogix 5, RSLogix 500, RSView32), FactoryTalk Linx, Avensys Intouch, Citect, and Kepware.
- Flexible DH+ Connections: Connect via the 2-pin Phoenix Blue Hose connector for direct wiring, or the 8-pin mini DIN cable to interface directly with PLC ports (like CH0 on SLC 5/04 or PLC-5 processors).
- Compact & Portable: A lightweight, USB stick-sized design that requires no external power supply—perfect for field engineers.
