Product Description:

The 8AC110.60-1 is a communication accessory in the 8AC Powerlink Modules series produced by B & R Automation. Designed as an add-on for ACOPOS motion systems, the module plugs directly into a servo drive expansion bay to provide networked control signals between drives, controllers, and higher-level PLCs. By embedding fieldbus connectivity inside the drive housing, it removes the need for a separate gateway and simplifies cabinet wiring in automation cells where synchronized axis motion is required.

The module communicates over a CAN interface, a deterministic serial bus widely used for real-time control. A fixed bitrate of 500 kbit/s is used to transmit command and status frames, providing a practical balance between cable length and noise tolerance in industrial settings. With compliant wiring, the network can span up to 60 m without repeaters, allowing several drives on the same machine frame to share one bus segment. Physical connection is made through a 9-pin male D-sub connector on the faceplate, which matches standard CAN pin assignments for power, ground, and differential data lines. Activity is shown by dual RXD/TXD LEDs, which provide a quick visual indication of bus traffic and node response.

The electronics are packaged as an ACOPOS plug-in module, so no external enclosure or DIN rail space is needed once it is fitted to the host drive. When installed in compatible ACOPOS servo drives, the board draws only up to 0.7 W, which keeps internal heat rise low and avoids additional cooling demands. The low power demand also reduces the load placed on the host drive's internal supply. Continuous operation is specified from 0 to +50 °C, matching typical control cabinet conditions. This temperature range supports installation alongside power electronics without requiring a separate cooling arrangement for the communication board.
