Allen-Bradley 1756-M16SE Sercos Interface Module

Allen-Bradley 1756-M16SE is a 16-axis SERCOS interface module for ControlLogix motion systems. It provides a dedicated SERCOS link between a ControlLogix controller and up to 16 servo drives on a SERCOS network, delivering real-time motion commands over a single digital fiber-optic link and reducing wiring by as many as 18 wires per axis. Placed in a 1756 ControlLogix chassis, the M16SE integrates with Rockwell’s motion ecosystem to drive Kinetix servo drives that support SERCOS, enabling tightly synchronized multi-axis motion across the bus. With 16-axis capability, it is well suited for applications requiring parallel servo control such as packaging lines, automated assembly, and CNC-like machinery where precise positioning and coordinated torque delivery are critical. The M16SE is part of the broader M03SE/M08SE family of SERCOS interface modules, which confirms its intended role as the servo-side I/O interface within a ControlLogix system. In practice, users deploy this module to simplify cabling on multi-axis servo installations while maintaining deterministic, real-time communication with the drives on the SERCOS network.
