Allen-Bradley 1788-CN2FF ControlNet to Foundation Fieldbus Linking Device

Description

The Allen-Bradley 1788-CN2FF is a high-performance linking device designed to bridge ControlNet networks with Foundation Fieldbus H1 segments. This module facilitates seamless communication and data exchange between the two protocols, allowing for the integration of Fieldbus-enabled field devices into a ControlNet-based control architecture.

Features

• Protocol Conversion: Enables transparent communication between ControlNet and Foundation Fieldbus H1 networks.
• Power Requirements: Operates on a standard 11-30 VDC power supply.
• Mounting: Designed for standard DIN-rail installation, ensuring space-efficient integration into control cabinets.
• Connectivity: Equipped with 9-pin Sub-D connectors for reliable network interfacing.
• Robust Design: Built to withstand typical industrial environments with specified vibration and temperature tolerances.

Technical Specifications

Installation Guidelines

• Ensure the power supply is disconnected before installing or removing the module from the DIN rail.
• Verify that the operating environment remains within the specified temperature range (0 to 60 degC) and humidity limits.
• Use appropriate shielded cabling for both ControlNet and Fieldbus connections to minimize electromagnetic interference (EMI).
• Ensure the module is securely snapped onto the DIN rail and that all 9-pin Sub-D connectors are fully seated and tightened.
• Maintain adequate clearance around the module to allow for proper airflow and cooling.

FAQ

What is the primary function of the 1788-CN2FF?

The 1788-CN2FF acts as a bridge, allowing a ControlNet network to communicate with and control Foundation Fieldbus H1 devices, effectively integrating disparate network segments into a unified control system.

Is this device suitable for high-vibration environments?

The module is rated for 0.5 g vibration at 10 to 500 Hz. It is intended for standard industrial cabinet mounting; if your application exceeds these vibration specifications, additional shock-absorbing mounting hardware may be required.
