It is critical to verify the physical width of your intended Modicon STB I\/O module before installation. High-density or specialty modules may require the wider STBXBA3000 (28.1 mm) base. These bases are not interchangeable due to the physical dimensions of the module housings.\u003c\/p\u003e\n\n\u003ch4\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eEnsure that the mounting bases are securely locked onto the DIN rail and tightly abutted against one another.
