Digital inputs/outputs

The EPP2334, EPP2338, EPP2339 and EPP2349 have digital channels which can be operated as inputs or outputs.

If the channels are operated as digital inputs, the modules record the binary control signals from the process level and transport them to the higher-level automation device. The sensors are supplied from the load voltage U_P.

If the channels are operated as a digital output, the modules forward the binary control signals of the automation device to the actuators at the process level. The outputs are short-circuit proof and protected against polarity reversal.
