Product Description:

The EL4014 is an analog output EtherCAT terminal manufactured by Beckhoff within the EL EtherCAT Terminals series. The module translates numerical values generated by a PLC into precise current signals for field devices, allowing actuators, valves, and transducers to receive commands through the bus terminal. Its compact housing fits into a standard terminal row, so analog output functions can be added to a machine without a separate I/O rack. The terminal communicates through EtherCAT, enabling the controller to exchange output data with the module as part of the connected terminal network.

The terminal draws power for its logic and output circuitry from a 24 V DC supply, eliminating the need for auxiliary supply rails. Each channel uses a 12-bit resolution, providing 4,096 discrete steps across the selected current range and setting the minimum output increment. Output accuracy is supported by a measuring error of ±0.1%, ensuring that commanded values are reproduced with minimal deviation. Each output supports a load resistance of less than 350 Ω, which helps prevent overcurrent and maintain linear operation. The housing has an IP20 protection rating, so the terminal must be installed inside a control cabinet. Signals use a single-ended topology, and the process image presents one 16-bit word per channel for straightforward addressing by the controller.

Time-sensitive systems benefit from EtherCAT distributed clocks support, and the module maintains DC jitter of less than 100 ns for tightly synchronized processes. The terminal provides 4 outputs that are refreshed in a multiplexed sequence to balance update speed with the available wiring space. A dedicated ground terminal can source up to 500 mA, allowing connected peripheral devices to share the supply rail without additional terminals. Installation uses a 35 mm DIN mounting rail, and the compact slice format preserves room for adjacent digital or analog terminals. Field conductors connect at the front of the housing, allowing access to wiring without removing neighboring modules from the terminal row.
