Allen-Bradley 1756-M08SE Sercos Interface Module

The Allen-Bradley 1756-M08SE Sercos Interface Module is an 8-axis SERCOS interface card for ControlLogix systems, enabling high-speed real-time servo communication over a SERCOS network between a 1756 controller and up to eight servo drives on a single module. Designed to mount in a 1756 ControlLogix chassis, the M08SE uses a single fiber-optic link to connect to compatible servo drives and is commonly used with Rockwell’s Kinetix servo families, including Kinetix 6000M, Kinetix 7000, and Ultra 3000 on SERCOS. Rockwell documentation identifies the M08SE as part of the 8-Axis SERCOS Motion Module family, with firmware in the 38.x series (for example, v38.001). Industry listings and literature consistently describe the 1756-M08SE as an 8-axis SERCOS interface module for ControlLogix, suitable for precise, synchronized motion control in automation and manufacturing applications. With eight axes supported, it enables synchronized control across up to eight servo channels while maintaining deterministic timing required for precision motion profiles in automation environments.
