Allen-Bradley 1756-M03SE | 3-Axis SERCOS Servo Module for ControlLogix Motion Control

Overview

The Allen-Bradley 1756-M03SE is a 3-axis servo module for the ControlLogix platform, using the high-speed SERCOS (Serial Real-Time Communication System) interface to communicate with intelligent digital servo drives. It supports data rates of 4 Mbit/s or 8 Mbit/s over noise-immune fiber-optic cables, making it ideal for real-time, high-precision motion control in demanding industrial environments.

This module integrates seamlessly with the RSLogix 5000 motion instruction set and axis configuration tools, providing a powerful and flexible solution for synchronized multi-axis applications.
