Beckhoff Automation EL4004 EtherCAT Terminal PLC Module

Beckhoff EL4004 EtherCAT Terminal is a four-channel analog output module for EtherCAT networks that provides four independent 0–10 V voltage outputs. Each channel delivers 12‑bit resolution (4096 steps), enabling precise control of analog actuators, valves, and other process equipment in automated systems. As part of the EL40xx family, the EL4004 supports distributed clocks for synchronized data transfer with other EtherCAT devices, helping maintain deterministic timing in multi‑node configurations. The module is designed to mount in Beckhoff EtherCAT terminal stacks and is driven by the EtherCAT bus, making it well suited for compact control panels and distributed automation nodes that require multiple precise voltage outputs. Applications include machine control, test rigs, and process control scenarios where four discrete 0–10 V signals must be generated from a single EtherCAT slave.
