Product overview
Attention
For switch off in the event of a fault, do no external sensor power supply
If the design of your installation is such that the power supply voltage Up is switched off in
the event of a fault, you must not power the connected sensors externally, but only through
the EP2339­0021! Otherwise, when the Up energy is switched off, the EP2339­0021 can
continue to draw energy from the external sensor power supply, and the outputs will not be
switched off!

2.9.2 EP2339­0022 ­ Introduction
Fig. 27: EP2339­0022
16 digital in or outputs, 24 V
DC
The EP2339­0022 EtherCAT Box has 16 digital channels, each of which can optionally be operated as an
input or as an output. A configuration if a channel should be used as input or as an output is not necessary;
the input circuit is internally connected to the output driver, so a set output is displayed automatically to the
input process image.
The outputs handle load currents of up to 0.5 A, are short­circuit proof and protected against inverse polarity.
The filter constant of the inputs is 3 ms.
The state of each signal is indicated by means of light emitting diodes. The signals are connected via M12
connectors.
