The EPP2xxx digital output modules are intended for the processing of digital/binary signals. They connect the binary control signals from the automation device on to the actuators at the process level. The outputs process different load currents. Typically, these are semiconductor driver blocks that forward the 24 V DC voltage to the actuators. Potential-free relay modules are also available. The outputs are short-circuit proof and feature channel-wise or block-wise diagnostic functions depending on the module.
