The EP2338-2002 EtherCAT Box has eight digital channels, which can each be operated as an input or output. It is not necessary to configure whether a channel (pins 2 and 4 of M12) is to be used as an input or output. The input circuit is permanently connected to the output driver internally so that a set output is also automatically displayed in the input process image. The inputs have a 10?¶Ãs filter. The outputs process load currents up to 0.5?A, are short-circuit proof and protected against inverse polarity. The sum current of all outputs is limited to 4?A. The connected sensors are supplied with power via US and are limited to 4?A. The signal state is displayed by LEDs; the signals are connected via screwable M12 connectors.
