Function and Positioning

The B&R 3IF672.9 serves as a cost-effective and versatile communication hub for mid-range automation systems. It provides one RS232 serial port for point-to-point connection with HMIs, scanners, or legacy devices, plus two electrically isolated CAN interfaces for CANopen or CAN 2.0 networks. It ensures reliable data transmission between PLCs, drives, sensors, and I/O modules. Featuring a hot-swappable and compact design, it simplifies installation, maintenance, and system upgrades without shutting down the entire station.
