Beckhoff EL2004 EtherCAT Terminal

The Beckhoff EL2004 is a 4-channel digital output EtherCAT Terminal designed for switching binary control signals from an automation system to actuators at the process level. Each output supports up to 0.5 A and is electrically isolated to ensure safe signal transmission. The terminal features short-circuit protection, reverse polarity protection, and supports various load types including ohmic, inductive, and lamp loads.

Compact, robust, and DIN rail mountable, the EL2004 is ideal for distributed I/O applications in harsh industrial environments.
