2.5.1 Introduction
Fig.21: EL2819
HD EtherCAT terminals, 16 digital output channels, 24V
DC
, 0.5A, with diagnostics
The EL2819 digital output terminal connects the binary control signals from the automation device on to the
actuators at the process level with electrical isolation. The EL2819 is protected against polarity reversal and
processes load currents with outputs protected against overload and short-circuit. The integrated diagnosis
can be evaluated in the controller and is indicated by the LEDs. Overtemperature and the lack of a voltage
supply to the terminal are supplied as diagnostic information. Beyond that each channel can among other
things signal a short circuit individually. The output behavior of the channels in the case of a bus error can be
parameterized. The switching state and any error of the output are indicated by the LED. Maintenance of the
application is simplified by the diagnosis. The power contacts are connected through.
The outputs are fed via the 24 V power contact in the EL2819. The conductors can be connected without
tools in the case of single-wire conductors using a direct plug-in technique.
The HD EtherCAT Terminal (High Density) with increased packing density is equipped with 16 connection
points in the housing of a 12-mm terminal block. The terminal is particularly suitable for space-saving use in
the control cabinets.
