The 6ES7228-1RC52-0AA0 is a Siemens SIMATIC EMS400S PSB-S safety module providing six digital inputs at 24 V DC, one synchronized DI for encoder or pulse trains, and three 48 V DC rail-signal interfaces for track-side or conveyor safety loops. The 24 V DC supply accepts 20.4 V to 28.8 V, and the module carries cULus and CE marks for panel compliance.
The 6ES7223-1BL32-0XB0 is a standard 16DI/16DO I/O module and is not a functional second-source for the PSB-S safety module. It lacks the synchronized DI and 48 V rail-signal interfaces required for the safety application.
The maximum operating temperature is 70 °C.
The minimum operating temperature is -40 °C.
The physical dimensions are identical, but the wiring differs due to different signal assignments. Rewiring and configuration changes are required.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
