Designed for a DIN-rail rack in a SIMATIC S7-300 system, it handles discrete sensor and actuator signals within one slot, saving rack space compared to separate input and output modules. ## Sourcing an obsolete BOM line We source this module to order against an RFQ; note that the successor 6ES7323-1BH01-0AA0 is the preferred procurement path for new builds or full swaps. The aggregate current of 2A and 0.5A per output are the same as the successor, so the replacement drops into existing wiring with no electrical re-rating.","metaTitle":"Siemens 6ES7323-1BH00-0AA0 SM 323 8DI/8DO, EOL","metaDescription":"EOL since 01.10.2004.
