Introduction
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).
 | Supply of the connected sensors from P24, not from L+ Unlike many other modules, the EPI2338 and ERI2338 IO-Link box modules 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. |
Notice | |
For shutdown in the event of a fault, do not supply sensors externally If the design of your installation is such that the additional 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, ERI23x8! 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.
