Fig. 23: EP2338
8 digital in or outputs, 24 V
DC
The EP2338 EtherCAT Box has eight digital channels, each of which can optionally be operated as an input
or as an output. A configuration if a channel should be used as input or as an output is not necessary; the
input circuit is internally connected to the output driver, so a set output is displayed automatically to the input
process image.
The outputs handle load currents of up to 0.5 A, are short­circuit proof and protected against inverse polarity.
The filter constant of the inputs is 10 µs.
The state of each signal is indicated by means of light emitting diodes. The signals are connected, optionally,
via M8 connectors (EP2338­0001) or M12 connectors (EP2338­0002).
Note
The connected sensors are powered via Up, not from Us
The EtherCAT Box EP2338 supplies digital sensors in contrast to many other modules from
the auxiliary voltage Up, not from the Control voltage Us! This happens because the con­
nectors can be used alternatively as input or as output. Anyway an overload of the sensor
supply (current > 0,5 A) is here also displayed by red shining of the LED Us.
