Product Description:
The 8I0IF108.400-1 is a communication module produced by B & R Automation for the 8I7 ACOPOS Inverters series. Installed on the drive backplane, this module provides deterministic POWERLINK networking so that multiple inverter segments can share real-time process data with a central controller. By adding Ethernet-based fieldbus capability directly at the drive, it removes the need for separate switches and simplifies wiring in distributed motion systems. This arrangement supports coordinated communication between connected inverter axes without adding a separate network module elsewhere in the control cabinet.
The compact housing has a height of 21 mm, a width of 41 mm, and a length of 74 mm. These dimensions allow the module to fit next to power units without increasing cabinet depth. A mass of 300 g keeps the additional load on the mounting assembly low during vibration. Data moves across the internal bus at a native rate of 100 Mbit/s, allowing inverter axes to exchange position, velocity, and diagnostic words within the network cycle. The front edge has four status indicators that show link, activity, and error states while the machine is operating. These indicators provide direct visual access to basic network conditions without requiring the enclosure to be disassembled.
External connectivity follows the Ethernet standard of 10/100 Base-TX. Physical coupling is provided through two shielded RJ45 hub ports, enabling a line topology and daisy-chained connections without an external hub. The POWERLINK ports support full-duplex traffic across connected network segments. Each segment may span up to 100 m between nodes when standard Category 5e cabling is used, allowing long conveyor or gantry installations to remain within network timing limits. Shielded connections help protect transmitted data from electromagnetic interference generated by nearby inverter power circuitry. The Ethernet interface carries control and diagnostic data without altering the drive’s power circuitry.
