The Beckhoff EM Terminal Modules series is a family of EtherCAT I/O modules designed for compact machine and cabinet installation with pluggable connection technology and direct integration into EtherCAT systems.
The series covers different functions, including digital output modules and motion interface modules, with examples in the provided set ranging from a 16-channel 24 V DC digital output module to a 4-channel motion interface for axis and servo drive control. EM modules are designed for standardized mounting and commissioning within the Beckhoff EtherCAT environment, with support for setup and parameterization through TwinCAT and associated EtherCAT device descriptions. The series also incorporates version and traceability features such as hardware and firmware identification, revision tracking, and Beckhoff Identification Code marking for product management and replacement control. Overall, the EM Terminal Modules series is intended for distributed automation tasks that require compact EtherCAT-based signal handling, modular installation, and application-specific I/O or motion functionality.
