IP23x2-Bxxx, M12, screw type
The IP2302-Bxxx digital I/O module combines four digital inputs and four digital outputs in one device. The outputs handle load currents of up to 0.5 A, are short-circuit proof and protected against inverse polarity. The state of each signal is indicated by means of light emitting diodes. The signals are connected via M12 screw type connectors.
