Siemens 6ES7523-1BL00-0AA0 is a SIMATIC S7-1500 SM 523 combined digital input/output module. The input section provides 16 channels at 24 V DC in one group, with a typical 3.2 ms input delay and Type 3 behavior according to IEC 61131. The output section provides 16 channels at 24 V DC and 0.5 A, arranged in groups of eight with 4 A per group. Siemens states that the module supports safety-oriented shutdown of output load groups up to SIL 2 and Category 2 / PL c within a suitable system. Delivery includes a push-in front connector, supporting controlled replacement and compact mixed-I/O expansion.
