Allen-Bradley 1788-EN2FFR 1788 Linking Devices Network Linking Module

Product Overview

The Allen-Bradley 1788-EN2FFR acts as a high-availability gateway bridging redundant EtherNet/IP networks with Foundation Fieldbus H1 segments. This network linking device features dual RJ45 EtherNet/IP connectors and two sets of H1 media terminals, ensuring seamless and fault-tolerant data exchange between modern control systems and field instruments. It operates on a 24-32V DC power supply and features an open-style chassis designed for standard DIN rail mounting. We supply this item as a 100% Brand New, factory-sealed unit.

Technical Specifications

Engineering Advantages

Redundant Network Architecture
The 1788-EN2FFR is engineered for mission-critical process automation environments. By supporting redundant EtherNet/IP connections alongside dual H1 media terminals, it eliminates single points of failure. If a primary network cable or switch fails, the module seamlessly maintains communication, ensuring your control system retains continuous visibility and command over field devices without costly downtime.

Seamless Protocol Bridging
This linking device efficiently translates high-speed EtherNet/IP traffic into Foundation Fieldbus H1 signals. It allows modern Logix-based controllers to easily integrate with legacy or specialized field instruments (such as smart transmitters and valve positioners) that operate on the Foundation Fieldbus protocol, simplifying your overall system architecture and reducing the need for multiple disparate gateways.

Standardized Industrial Installation
Designed for rapid deployment in control cabinets, the open-style module mounts directly onto a standard DIN rail. The clear terminal blocks for both the 24-32V DC power and the H1 media simplify wiring and troubleshooting. Its compact 1.20 lbs footprint conserves valuable panel space while delivering robust telecommunications adaptability.

FAQs

Q: What network protocols does the 1788-EN2FFR connect?
A: This module acts as a bridge between a redundant EtherNet/IP network (using dual RJ45 ports) and Foundation Fieldbus H1 segments (using two sets of H1 media terminals), allowing seamless data exchange between the two protocols.

Q: What is the power requirement for this linking module?
A: The 1788-EN2FFR requires a DC power supply ranging from 24 to 32 volts. Ensure your control panel provides a stable voltage within this range for optimal operation.

Q: How does this module improve network reliability?
A: It features built-in redundancy for both the EtherNet/IP and Foundation Fieldbus connections. This dual-path capability ensures that communication remains active even if one network link experiences a physical fault or interruption.

Q: How is the 1788-EN2FFR mounted in a control panel?
A: The module features an open-style industrial design that snaps directly onto a standard DIN rail, allowing for quick installation, secure mounting, and easy removal for maintenance or replacement.
