The IE2322 digital I/O module combines four digital inputs and four digital outputs in one device. The outputs handle load currents of up to 2?A, are short-circuit-proof and protected against inverse polarity. The total current for all four outputs is limited to 4?A. The input filter is 3?ms. The state of each signal is indicated by means of light emitting diodes. The signals are connected via M12 screw type connectors.
