It is critical to note that optional output boards (such as relay outputs, transistor outputs, or linear current\/voltage outputs) are sold separately. Ensure that any expansion card added to the rear slots matches the physical slot designation (Slot A, B, C, D, or E) specified in the system design. When retrofitting legacy K3HN series panels, verify overall depth specifications, as the K3HB series requires a different rear panel depth clearance depending on the terminal covers used.\u003c\/p\u003e\n\n\u003ch4\u003eApplication Pitfalls \u0026amp; Engineering Notes\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eIn multi-unit, side-by-side installations, thermal build-up inside closed control cabinets can affect measurement stability.
