Beckhoff EL4004 EtherCAT Terminal

The Beckhoff EL4004 is a high-precision 4-channel analog output EtherCAT Terminal designed to generate voltage signals in the 0–10 V range. Ideal for industrial automation systems, the EL4004 delivers 12-bit resolution outputs, electrical isolation, and user synchronization capabilities. All channels share a common ground and are powered via the 24 V DC power contacts, with LED indicators providing real-time signal status.

With integrated distributed clock support and optional watchdog functionality, the EL4004 is well-suited for time-critical and safety-sensitive applications.
