The Beckhoff EL4004 is a compact EtherCAT terminal with four analog voltage outputs for precise motion and process control. Delivering 0…10 V per channel with 12-bit resolution, it integrates seamlessly into EtherCAT I/O systems and provides reliable signal conditioning for PLC and IPC applications in industrial automation.

Engineered for accuracy and uptime, the EL4004 offers a typical conversion time of ~250 µs and a relative output error below 0.1%. Outputs are short-circuit proof for loads greater than 5 kΩ, while 500 V isolation between E-bus and signal increases resilience in electrically noisy environments. Distributed clocks are supported with precision << 1 µs for deterministic timing, and an optional watchdog with ramp and user synchronization enhances safety and startup behavior. The terminal is powered via 24 V DC power contacts, mounts on a 35 mm DIN rail, and meets IP20 and international approvals including CE, UL, ATEX, and IECEx.

Whether you are driving actuators, valves, or analog setpoints, this 4-channel 0…10 V module helps reduce panel width and commissioning time while maintaining consistent output quality, and to support your procurement standards it is supplied with a 1-year warranty as part of our professional after-sales service.
