Firm and hardware version
The documentation refers to the firm and hardware status that was valid at the time it was prepared.
The properties of the modules are subject to continuous development and improvement. Modules having
earlier production statuses cannot have the same properties as modules with the latest status. Existing
properties, however, are always retained and are not changed, so that these modules can always be
replaced by new ones.
The firmware and hardware version (delivery state) can be found in the batch number (D number) printed at
the side of the IO-Link box module.
Syntax of the batch number (D number)
D: WW YY FF HH
WW - week of production (calendar week)
YY - year of production
FF - firmware version
HH - hardware version
Example with D No. 29 10 02 01:

8 digital outputs, 24VDC, Imax 0.5A
The EPI2008 IO-Link Box with digital outputs connects binary control signals from the controller to the
actuators at the process level. The 8 outputs handle load currents of up to 0.5A, and indicate their status
through light emitting diodes.
The signals are connected optionally via M8 connectors (EPI2008-0001) or M12 connectors
(EPI2008-0002,). The outputs are short-circuit proof and protected against inverse connection.

16 digital outputs 24VDC, Imax 0.5A (Σ4A)
The EPI2809 IO-Link Box with digital outputs connects the binary control signals from the controller on to the
actuators at the process level.
The 16 outputs handle load currents of up to 0.5A each, although the total current is limited to 4A. This
makes these modules particularly suitable for applications in which not all of the outputs are active at the
same time, or in which not all of the actuators draw 0.5A current.

8 digital in or outputs, 24VDC
The EPI2338 IO-Link Box has eight 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 short-circuit proof and protected against inverse polarity.
The filter constant of the inputs is 3.0ms (EPI2338-0001, EPI2338-0002).
EPI2xxx 15Version: 1.1.0

Product overview
The state of each signal is indicated by means of light emitting diodes. The signals are connected, optionally,
via M8 connectors (EPI2338-x001) or M12 connectors (EPI2338-x002).
Note
The connected sensors are powered via 2L+, not from L+
The IO-Link Box EPI2338 supplies digital sensors in contrast to many other modules from
the additional supply voltage 2L+, not from the voltage L+! This happens because the con-
nectors can be used alternatively as input or as output. Anyway an overload of the sensor
supply (current>0.5A) is here also displayed by red shining of the LED “24V”.
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 additional supply voltage 2L+ is switched off
in the event of a fault, you must not power the connected sensors externally, but only
through the EPI23x8! Otherwise, when the 2L+ energy is switched off, the EPI23x8 can
continue to draw energy from the external sensor power supply, and the outputs will not be
switched off!
