Siemens 6ES7323-1BL00-0AA0 is the SIMATIC S7-300 SM 323 digital I/O module with galvanic isolation, delivering 16 digital inputs and 16 digital outputs for 24 V DC signaling on the S7-300 backplane. The module interfaces via a 1x 40-pole backplane connector and carries a total current rating of 4 A, with a 24 V DC supply across the I/O network. This isolated SM 323 block is designed for discrete sensing and actuation in industrial automation, enabling compact, integrated control of sensors and actuators within a SIMATIC S7-300 system.
