Product Description:
The EL9110 is a power supply terminal produced by Beckhoff as part of the EL EtherCAT Terminals series. Within an EtherCAT I/O station, the device provides a new power infeed for the control voltage while carrying bus communication forward unchanged. This function allows separate power zones to be created so that short circuits or overloads remain localized, a requirement in many machine and plant installations that rely on continuous fieldbus operation.
Rated for a nominal voltage of 24 V DC, the terminal can pass this supply through its power contacts while isolating it from the communication lines by up to 500 V. The internal electronics draw a typical 90 mA from the E-bus, minimizing the load on the upstream coupler. Current supplied to the application side can reach 10 A, so actuators and sensors with higher consumption can be powered without an external feed module. In the process image, the module occupies 1 bit, which the controller interprets as the state of the power path and diagnostic information. These electrical values make the terminal suitable for compact control cabinets where energy distribution and status signaling must share the same footprint.
The housing provides one additional power contact and is fastened to a 35 mm DIN rail. There is no direct electrical connection to the rail, so grounding is handled through the built-in PE contact. The terminal can operate at up to 95% relative humidity without condensation, and the plastic enclosure meets IP20 requirements for finger protection inside closed panels. An integrated power LED provides immediate visual confirmation that the supply is present, while the terminal’s status output reports undervoltage or overload events to the PLC. The dedicated PE path carries protective earth independently of the mounting rail.
