1711-FF Allen Bradley

Description

Product Name: 1711-FF   Allen Braley I/O module

Product details:  

The Allen-Bradley 1711-FF is a specialized module within the Rockwell Automation ecosystem, primarily designed for Foundations Fieldbus (FF) connectivity. It acts as a bridge between the high-level control system (like Logix5000) and field-level instrumentation.

## Product Overview

The 1711-FF series is engineered to integrate fieldbus devices into an Integrated Architecture. It enables bidirectional communication, allowing the controller to not only receive process data but also monitor device health and perform remote configuration.

## Technical Specifications

While specific parameters can vary slightly based on the firmware revision, the core technical profile includes:

## Key Advantages

• Reduced Wiring: By using a “trunk and spur” topology, it significantly reduces the amount of cable required compared to traditional point-to-point 4-20mA loops.

• Enhanced Diagnostics: It provides “Asset Management” capabilities, allowing maintenance teams to see predictive alerts (e.g., a valve sticking) before a failure occurs.

• Interoperability: It supports a wide range of third-party instruments, ensuring you aren’t locked into a single hardware vendor for sensors and actuators.

• Digital Accuracy: Eliminates the need for digital-to-analog conversions, preserving the integrity of the signal from the field to the controller.

## Critical Considerations (Precautions)

• Terminators: A Foundation Fieldbus segment must have exactly two terminators (one at each end of the trunk) to prevent signal reflections and data loss.

• Power Conditioning: Do not use standard DC power supplies directly on the H1 segment; specialized Fieldbus power conditioners are required to prevent the power supply from absorbing the high-frequency communication signal.

• Shielding: Ensure proper grounding and shielding of the Fieldbus cable to protect against Electromagnetic Interference (EMI) in industrial environments.

• Segment Loading: Always calculate the total current draw of all connected field devices to ensure it does not exceed the module’s or power conditioner’s capacity.

## Common Applications

The 1711-FF is most prevalent in “process” industries where complex instrumentation is common:

• Oil & Gas: Monitoring pressure and flow at remote wellheads or refineries.

• Chemical Processing: Managing complex valve manifolds and temperature transmitters.

• Water/Wastewater: Integrating smart meters and chemical dosing pumps.

• Pharmaceuticals: Precise environmental monitoring and batch control.
