Product Description:

The EL2024 digital output terminal is manufactured by Beckhoff as part of the EL EtherCAT Terminals series. Within an EtherCAT I/O strand, this device provides four independent 24 V DC switching points so a controller can energize field actuators directly from the DIN rail without separate relays. By translating the real-time bus commands into discrete power lines, it supports compact, distributed automation architectures in machine tools, packaging lines, and material-handling stations.

Each of the four channels is routed through a 2-wire actuator connection and delivers a nominal output voltage of 24 VDC. Up to 2 A per channel can be sourced continuously, allowing ohmic, inductive, or lamp loads to be driven without external amplifiers. The terminal turns on in 40 µs and turns off in 200 µs, permitting fast cycle times when valves or coils must follow rapid command sequences. All switching states are mapped as 4 output bits in the EtherCAT process image, giving straightforward access from the PLC program. Output stages are declared non-reactive, so current drawn by one channel does not influence the remaining outputs. Power for the driver electronics is taken from the E-Bus that runs along the terminal row, eliminating separate logic wiring.

Mechanical and protective characteristics complement the electrical data. The enclosure meets the IP20 protection class for safe installation inside a control cabinet and snaps onto a 35 mm DIN rail for quick removal or repositioning. Four integrated ground points create a defined reference plane for shield terminations and leakage paths, and built-in reverse voltage protection prevents damage if the supply polarity is crossed. Should a fault occur on the load side, short-circuit protection disconnects the affected channel, conserving the remainder of the networked system.
