Beckhoff EL2809 EtherCAT Terminal

The Beckhoff EL2809 is a high-density 16-channel digital output EtherCAT Terminal for 24 V DC actuators. Designed to optimize cabinet space, this terminal enables direct connection of multi-channel actuators using 1-wire technology. Each output is short-circuit and overload protected, ensuring reliable operation in demanding control environments.

LED indicators for each channel simplify diagnostics, while its robust reverse-polarity protection and wide temperature range make it suitable for industrial automation across sectors. Ideal for controlling ohmic, inductive, and lamp loads.
