Beckhoff EL4022 is a two-channel EtherCAT analog output terminal that provides 4–20 mA current-output signals with 12‑bit resolution. Each channel can source a precise current in the 4–20 mA range, and the outputs share a common 0 V DC reference with the terminal's power supply to simplify field wiring. As part of the EL40xx family, the EL4022 seamlessly integrates into Beckhoff EtherCAT networks and is commonly used to drive current-loop devices such as valves, actuators, and other process-control elements. Mountable as a standard EtherCAT bus terminal, it enables compact, scalable analog control within industrial automation systems.
