EP2338-x00x | 8-channel digital input or output 24 V DC, freely configurable

The EP2338 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 (EP2338-000x) or 3 ms (EP2338-100x).

The state of each signal is indicated by means of light emitting diodes. The signals are connected via M8 (EP2338-x001) or M12 connectors (EP2338-x002).
