Beckhoff Automation EL9100 Voltage Supply Terminal

Beckhoff EL9100 is a 24 V DC power-supply terminal for the EtherCAT EL9xxx system that enables a separate potential group and delivers up to 10 A of supply current. Designed to be placed anywhere between input and output terminals, the EL9100 lets you extend the standard 24 V supply to adjacent terminals and, in high‑current scenarios, increase the current available to downstream devices. Key specifications include nominal voltage of 24 V DC, a current load capability of up to 10 A, and electrical isolation of 500 V between the E‑bus and field potential; it also provides a protective earth (PE) contact and a single additional power contact to connect an alternate supply path. A green power LED indicates energization for quick status checks. Common applications include powering distant Beckhoff I/O blocks within an EtherCAT network, creating a separate potential group for high‑current loads, and ensuring stable voltage distribution across a terminal segment without distributing the main supply through all devices. The EL9100 integrates seamlessly with other EL9xxx terminals, enabling flexible potential distribution and organized power architecture in compact automation cabinets.
