Allen-Bradley 1756-M08SE Discrete Input Output Module

The Allen-Bradley 1756-M08SE is an eight-axis SERCOS servo motion control module for ControlLogix systems. It provides a dedicated SERCOS interface within a 1756 backplane chassis, enabling high-speed, multi-axis servo control for precision motion applications. The module supports up to eight servo axes and uses a fiber-optic link to servo drives for robust noise immunity in demanding environments. Electrical characteristics include a maximum power dissipation of 5 W, with backplane power draw of 5.1 V DC at up to 760 mA and 24 V DC at up to 2.5 mA. The M08SE is designed for installation in a ControlLogix 1756 system and works with compatible motion components to deliver coordinated position and velocity control across all axes. Common applications include automated manufacturing tasks requiring synchronized axis motion, such as packaging lines, CNC-related equipment, and robotic work cells. When integrated with the ControlLogix motion suite, this module provides a scalable solution for multi-axis servo control via the SERCOS interface, enabling reliable, deterministic operation across eight axes.
