Designed for robust industrial environment expansion, the Beckhoff C9900-E251 slotbox allows operators to extend compatible Beckhoff Industrial PCs with two additional plug-in card slots. 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 C9900-E251 provides flexibility in layout configuration and system hardware scaling without upgrading the primary PC chassis.
