Basic Information

  • Model: 3IF671.9

  • Manufacturer: B&R Industrial Automation

  • Series: SYSTEM 2005 Interface Module

  • Type: Multi-Communication Interface Module

  • Installation: Plug-in design, compatible with 2005 series CPU and backplane slots

  • Galvanic Isolation: 2.5 kV isolation for all communication channels

  • Protection Class: IP20 when installed in control cabinet

Function and Positioning

This module acts as a universal communication gateway for industrial automation systems. It provides three distinct communication interfaces to connect with serial devices such as printers, scanners, and displays via RS232; with drives, sensors, and meters via RS485/RS422; and with CANopen devices and CAN-based controllers via CAN port. The electrical isolation design suppresses electromagnetic interference effectively. It reduces the main CPU’s communication load, enhances system flexibility, and acts as a key link for multi-device interconnection in electromechanical and process control systems.
