Product Description:
The EL4112 analog output terminal is manufactured by Beckhoff within the EL EtherCAT Terminals series. As a field-level I/O module, it converts digital setpoints from an EtherCAT controller into proportional current signals for external actuators used in process or motion equipment. The terminal mounts on a DIN rail and communicates through the EtherCAT backplane, allowing decentralized analog output generation close to the load while reducing wiring complexity.
The module offers 2 current output channels, each using a 16-bit converter configured for simultaneous updating so both outputs change at the same instant. The process image presents two 16-bit data words and status information to the controller, and each channel is single-ended with respect to ground. The channels support loads below 500 Ω and can source between 0–20 mA, providing compatibility with many industrial actuators and transducers. The maximum update rate is 20 kSps per channel, supporting rapid output adjustments in applications that require responsive current control. The EtherCAT backplane can operate with a minimum cycle time of 50 µs, allowing the controller to exchange process data at short intervals. This combination supports high-speed dosing, tension control, and servo-hydraulic applications in which coordinated output changes are important.
The internal supply contacts can transfer up to 4 A, allowing neighboring terminals to draw sensor or actuator power without additional supply wiring. The enclosure has an IP20 protection rating and is intended for installation inside a suitable control cabinet. Proper operation is supported at ambient temperatures from 0 to +55 °C, covering the temperature range found in many industrial control enclosures. During storage or transportation, the electronics can withstand temperatures from −25 °C to +85 °C. The compact terminal format allows multiple EtherCAT modules to be installed together on the same DIN rail while maintaining access to field wiring. Its single-ended channel arrangement provides a straightforward connection method for grounded current-loop devices.
