The Allen-Bradley 1756-M08SEF Sercos Interface Module is an 8-axis SERCOS motion interface for ControlLogix systems, mounting in a 1756 backplane to connect a Rockwell Automation controller with SERCOS-compatible servo drives. It enables high-speed, real-time communication across up to eight axes, making it suitable for precise, synchronized motion tasks in automation and robotics applications. As part of the 1756 SERCOS interface family, this module’s firmware for the 8-axis variant is listed as v38.001 on Rockwell’s official product page.
