Introduction

HD EtherCAT Terminals, 16 digital output channels, 24 V
The EL2809 digital output terminal connects the binary control signals from the automation device on to the
actuators at the process level with electrical isolation. The EL2809 is protected against polarity reversal and
processes load currents with outputs protected against overload and short-circuit. The EtherCAT Terminal
contains 16 channels whose signal state is indicated by LEDs. The power contacts are connected through.
The outputs of the EL2809 are fed via the 24 V power contact and the outputs of the EL2889 via the 0 V
power contact. The conductors can be connected without tools in the case of single-wire conductors using a
direct plug-in technique.
The HD EtherCAT Terminals (High Density) with increased packing density are equipped with 16 connection
points in the housing of a 12-mm terminal block. They are particularly suitable for space-saving use in control
cabinets.
