6ES7323-1BL00-0AA0 Siemens SIMATIC S7-300 Digital module SM323 16DI 16DO 24VDC 0.5A
The Siemens 6ES7323-1BL00-0AA0 is a versatile and widely used combined digital I/O module from the SIMATIC S7-300 programmable logic controller (PLC) family. It integrates 16 digital inputs and 16 digital outputs in a single compact unit, making it an ideal solution for space-constrained control cabinets where both sensing and actuation functions are required—such as in packaging machines, conveyor systems, assembly lines, and material handling equipment.
Designed for reliability in demanding industrial environments, this module supports 24 V DC signaling, features optical isolation between field circuits and the backplane bus, and includes built-in protection against overloads and short circuits on the output side. Fully compatible with STEP 7 (Classic) and TIA Portal, the 6ES7323-1BL00-0AA0 simplifies engineering, reduces wiring complexity, and lowers total system cost by consolidating two I/O functions into one DIN-rail mounted module.
