EL4001
by Beckhoff
The Beckhoff EL4001 is an advanced analog output terminal from the EL EtherCAT Terminals series, designed by Beckhoff for high-precision industrial automation. This terminal features a single analog output channel with a resolution of 16 bit and an output voltage range of 0–10 V, making it ideal for controlling actuators, valves, and other analog devices. With a typical conversion time of ~100 μs, the EL4001 ensures rapid signal generation and responsiveness in demanding applications. Its primary function is the reliable generation of precise analog voltages in EtherCAT networks, supporting seamless integration into modern control systems.
In terms of specifications, the EL4001 is distinguished by its distributed clocks capability, offering a synchronization accuracy better than 1 μs to guarantee tightly coordinated output across multiple I/O nodes. The module draws a typical E-bus current consumption of 140 mA and an additional power contact current consumption of 40 mA from a 24 V DC (power contacts) supply. The output error remains below 0.1% of full scale, ensuring high fidelity between the commanded and actual voltages. Optional features such as user synchronization and user-specific output ramps provide enhanced flexibility for custom signal profiling.
Built for durability and safety, the EL4001 supports a minimum load impedance of >>5 kΩ (short-circuit proof)>> to protect connected devices against overloads. The terminal also offers an optional watchdog function to maintain outputs at a safe default level during communication faults. Weighing only approx. 60 g, the compact design allows for efficient mounting in space-constrained panels. Powered via standard 24 V DC power contacts and complying with EtherCAT network requirements, the EL4001 delivers precise, reliable analog outputs with built-in safety and synchronization features. This combination of accuracy, robustness, and seamless integration makes the EL4001 invaluable in industrial automation environments where coordinated voltage control and system reliability are paramount.
