Beckhoff Automation EL9100 Voltage Supply Terminal

The Beckhoff EL9100 is a 24 V DC, 10 A potential supply terminal in the EL9xxx EtherCAT Terminal family, designed to distribute the standard 24 V supply to additional terminal groups within a Beckhoff I/O chassis. It provides a dedicated feed between input/output sections to create separate 24 V potential zones, enabling higher-current loads to be powered without burdening the central bus. Key specs include a nominal voltage of 24 V DC, a current load rating of up to 10 A, and 500 V electrical isolation between the E-bus and field potential, with a protective earth (PE) contact included. A green power LED indicates the terminal is supplying power, and the unit supports a renewed infeed along with one additional power contact for distributing +24 V to another terminal. This module is commonly used to power downstream Beckhoff terminals and 24 V devices (sensors, actuators, and other field devices) in larger EtherCAT configurations, helping to simplify power distribution while maintaining electrical isolation between control and power domains.
