This expansion unit is constructed with a fanless aluminum housing engineered specifically for space-saving control cabinet installation. It establishes a high-speed link with the host controller via a PCIe x1 interface, requiring a matching PCIe module (such as the C9900-E236 or C9900-E239) installed within the primary PC. By facilitating remote slot placement, the \u003cstrong\u003eC9900-E251\u003c\/strong\u003e provides flexibility in layout configuration and system hardware scaling without upgrading the primary PC chassis.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSturdy, fanless aluminum housing ideal for demanding control cabinet environments.\u003c\/li\u003e\n
