2.7.1 INTRODUCTION
SmartWire-DT I/O module EU5E-SWD-4DX provides four digital inputs I0 to
I3. The inputs are three-wire digital inputs, and the module also includes the
24 V supply for them.
The inputs' status is indicated with the help of LEDs.
The SmartWire-DT diagnostic LED is used to signal the network's/module's
status.

2.7.3 Engineering
The four inputs use a three-wire connection configuration.
A 24 V supply voltage is available for each input. The maximum current draw
for each input is 0.5 A. The supply is short-circuit proof.
On short circuit the SmartWire-DT diagnostics LED flashes and the diagnos-
tic bit is set in the user program. When the short circuit is removed, the sup-
ply voltage is automatically applied again.
