This EtherNet/IP adapter facilitates seamless connectivity between field sensors, actuators, and your central control network. Built for mission-critical industrial environments, the 5094-AENTR supports Gigabit Ethernet speeds and advanced redundancy protocols, ensuring that your production line remains operational even in the event of a network cable failure. Its robust design and high-speed data throughput make it the premier choice for automotive assembly, food processing, and complex material handling systems.

Technical Specifications

Engineering Advantages

Superior Network Resiliency (DLR & PRP)

The Allen-Bradley 5094-AENTR is engineered to eliminate single points of failure. By supporting Device Level Ring (DLR) and Parallel Redundancy Protocol (PRP), this adapter creates multiple communication paths. If a network cable is severed or a switch fails, the system switches paths instantaneously, preventing production downtime and expensive data loss.

Gigabit Throughput for Data-Intensive I/O

With auto-sensing 10/100/1000 Mbps ports, this adapter future-proofs your industrial network. High-speed Gigabit communication allows for real-time diagnostics and high-resolution analog data processing, which is essential for modern "Smart Factory" initiatives and high-precision motion control applications.

Rugged Industrial Design

Designed for harsh environments, the 5094-AENTR features a broad operating temperature range and robust isolation between power and the backplane. Its compact footprint (92.7 x 94.0 x 96.5 mm) ensures it fits into standard control cabinets while providing massive communication power to all connected FLEX 5000 I/O modules.

Installation & Configuration Guide

• Mounting: Snap the adapter onto a standard 35mm DIN rail. Ensure the module is securely latched to prevent vibration-related communication drops.
• Wiring: Connect the 24V DC power supply using 22-14 AWG wire. A dedicated 2.5mm wire should be used for the functional earth connection to ensure proper grounding and noise immunity.
• Removable Terminal Block (RTB): Utilize the included RTB for fast and reliable field wiring. When installing, torque the terminal screws to 0.4 N-m (3.5 lb-in) to maintain signal integrity.
• Network Setup: Plug your Ethernet cables into the dual RJ45 ports. The adapter will auto-negotiate the highest possible speed (up to 1000 Mbps) with your industrial switch or PLC.

Technical FAQs

Q1: Is the 5094-AENTR compatible with older FLEX I/O modules?

A1: No, the 5094-AENTR is designed exclusively for the FLEX 5000 I/O platform. It is not backward compatible with the older 1794 FLEX I/O series.

Q2: What is the benefit of the dual Ethernet ports?

A2: The dual ports allow for flexible network topologies, including star, linear (daisy-chain), and redundant ring (DLR) configurations, reducing the need for external switches in your control cabinet.

Q3: Does this Allen-Bradley adapter support Safe Torque Off (STO)?

A3: While the adapter manages communication, safety functionality is determined by the specific FLEX 5000 Safety I/O modules connected to it. This adapter seamlessly carries safety data via CIP Safety over EtherNet/IP.
