Beckhoff EL5101 | 1-Channel Incremental Encoder Interface Terminal

Beckhoff EL5101 | 1-Channel Incremental Encoder Interface Terminal

Overview

The Beckhoff EL5101 is a 1-channel incremental encoder interface terminal, designed for connecting incremental encoders with differential inputs (RS422) to an EtherCAT-based control system. It supports A, B, and optional C (zero) channels and enables precise position, speed, and direction acquisition, making it ideal for motion control and automation applications.

Thanks to its compact size, fast sampling, and integration with TwinCAT, the EL5101 provides a powerful solution for high-resolution encoder feedback in real-time control systems.
