HD EtherCAT Terminals, 8 digital output channels, 24 V
DC
, 0.5 A
The EL2808 digital output terminal connects the binary control signals from the automation device on to the
actuators at the process level with electrical isolation. The EL2808 is protected against polarity reversal and
processes load currents with outputs protected against overload and short-circuit. The EtherCAT Terminal
contains eight channels, consisting of a signal output and 0 V, whose signal states are displayed by LEDs.
The power contacts are connected through.
The outputs are fed via the 24 V power contact in the EL2808. 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.
