Description:
The Allen‑Bradley 1734‑AENTR is a dual‑port EtherNet/IP adapter for POINT I/O systems from Rockwell Automation, serving as the left‑most starter module to connect POINT I/O to EtherNet/IP networks, supporting Device Level Ring (DLR) redundancy, 10/100 Mbps auto‑negotiation, and up to 63 Series C+ I/O modules via POINTBus, ideal for high‑availability distributed industrial automation needing deterministic, redundant communication with ControlLogix/CompactLogix controllers.
Product Overview:
This open‑style, DIN‑rail mounted (IP20) adapter runs on 10–28.8V DC (nominal 24V DC), powers I/O modules via POINTBus (1A max @ 5V DC), and has 4 dual‑color status LEDs (network 1/2, module, POINTBus, power) for fast diagnostics. It enables DLR for network redundancy, RIUP (Removal and Insertion Under Power) for hot‑swapping, reverse polarity protection, and seamless integration with Logix controllers for real‑time I/O control in manufacturing, process automation, and remote I/O applications.
Key Features:
- Dual RJ‑45 ports (10/100 Mbps, auto‑negotiation) supporting DLR, star, tree, and linear topologies for redundant, flexible network design
- Powers up to 63 Series C+ POINT I/O modules via POINTBus (1A @ 5V DC) for scalable distributed I/O systems
- 4 dual‑color LEDs for instant troubleshooting of network links, module health, POINTBus communication, and power states
- RIUP support allows hot‑swapping I/O modules without system shutdown, cutting maintenance downtime
- Reverse polarity and overvoltage protection boost durability in harsh industrial settings
- Supports up to 5 rack‑optimized connections for digital I/O and 25 direct connections for specialty/analog modules for efficient data exchange
