ER2338-x00x | 8-channel digital input or output 24 V DC, freely configurable

The ER2338 EtherCAT Box has eight digital channels, each of which can optionally be operated as an input or as an output. A configuration for using a channel as input or output is not necessary; the input circuit is internally connected to the output driver, so that a set output is displayed automatically in 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 10 µs (ER2338-000x) or 3 ms (ER2338-100x).

The state of each signal is indicated by means of light emitting diodes. The signals are connected via M8 (ER2338-x001) or M12 connectors (ER2338-x002).

The EtherCAT Box modules with zinc die-cast housing are ready for use in harsh industrial and process environments. With the fully sealed design and metal surfaces the ER series is ideal for applications requiring enhanced load capacity and protection against weld spatter, for example.
