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:
29 - week of production 29
10 - year of production 2010

8 digital outputs 24VDC, Imax 0.5A
The EPI2008-000x and ERI2008-000x IO-Link box modules with digital outputs switch binary control signals
from the controller to the process level to the actuators. The eight outputs process load currents up to 0.5A
and indicate their signal state via LEDs.
The signal connection is made optionally via M8 (EPI2008-0001, ERI2008-0001) or M12 connectors
(EPI2008-0002, ERI2008-0002). The outputs are short-circuit proof and protected against polarity reversal.
The IO-Link box modules with zinc die-cast housing (ERIxxxx) are ready for use in harsh industrial and
process environments. With the fully sealed design and metal surfaces the ERI series is ideal for
applications requiring enhanced load capacity and protection against weld spatter, for example.

16 digital outputs, 24VDC, Imax 0.5A (Σ 4A)
The EPI2809-002x and ERI2809-002x IO-Link boxes with digital outputs switch binary control signals from
the controller to the process level to the actuators.
The 16 outputs process load currents 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 actuators require signal currents of 0.5A.
The signal state is indicated by means of LEDs. The signals are connected via M8 connectors
(EPI2809-0021, ERI2809-0021) or M12 connectors (EPI2809-0022, ERI2809-0022). All outputs are short-
circuit proof and protected against polarity reversal.

8 digital inputs or outputs, 24VDC
The EPI2338-000x and ERI2338-000x IO-Link box modules have 8 digital channels, each of which can be
operated as inputs or outputs. A configuration whether a channel is to be used as input or output is not
required; the input circuit is internally connected to the output driver so that a set output is automatically
displayed in the input process image.
The outputs process load currents up to 0.5A, are short-circuit proof and protected against polarity reversal.
The filter constant of the inputs is 3.0ms (EPI2338-000x, ERI2338-000x). The state of each signal is
indicated by means of light emitting diodes. The signals are optionally connected via M8 connectors
(EPI2338-0001, ERI2338-0001) or M12 connectors (EPI2338-0002, ERI2338-0002).

Product overview
EPI2xxx, ERI2xxx18 Version: 1.8
Supply of the connected sensors from P24, not from L+
Unlike many other modules, the EPI2338 and ERI2338 IO-Link boxes supply digital sensors from
the additional supply voltage P24 and not from the voltage L+! This is because the connections can
be used either as input or output. Nevertheless, an overload of the sensor supply (current>0.5A)
is also indicated here by the illuminated red "24V" LED.
NOTE
For shutdown in the event of a fault, do not supply sensors externally
If the design of your installation is such that the additional power supply voltage P24 is switched off in the
event of a fault, you must not power the connected sensors externally, but only through the EPI23x8, ER-
I23x8! Otherwise, when the P24 energy is switched off, the EPI23x8, ERI23x8 can continue to draw energy
from the external sensor supply, and the outputs will not be switched off.
The IO-Link box modules with zinc die-cast housing (ERIxxxx) are ready for use in harsh industrial and
process environments. With the fully sealed design and metal surfaces the ERI series is ideal for
applications requiring enhanced load capacity and protection against weld spatter, for example.
