## Overview of the PE-2SD1-R10 The **PE-2SD1-R10** is a specific industrial electronic component, primarily categorized as a **PCI Express (PCIe) Riser Card**. It is manufactured by IEI Integration Corp and is designed to expand or redirect the connectivity of a motherboard's expansion slots, typically within rackmount chassis or compact industrial computers. --- ### Technical Specifications The following table outlines the primary electronic and physical characteristics of the PE-2SD1-R10: | Feature | Specification | | :--- | :--- | | **Interface Type** | PCI Express (PCIe) | | **Slot Configuration** | 2 x PCIe x1 Slots | | **Input Interface** | 1 x PCIe x4 (Physical Connector) | | **Form Factor** | Riser Card (Right-Angle / Vertical) | | **Compatibility** | IEI PICMG 1.3 Full-size SBCs | | **Dimensions** | Standardized for 2U or specific industrial chassis | --- ### Electronic Components and Design The PE-2SD1-R10 acts as a bridge. While it is a "passive" or "minimal-logic" board, its electronic design focuses on signal integrity and power distribution: 1. **Trace Routing:** The PCB (Printed Circuit Board) uses high-frequency impedance-controlled traces to ensure that the PCIe signals do not degrade between the motherboard and the peripheral cards. 2. **Power Delivery:** The board includes power planes to distribute **+3.3V, +12V, and +5V** from the main golden finger (input) to the two PCIe x1 slots. 3. **Decoupling Capacitors:** Small surface-mount (SMD) capacitors are placed near the slots to filter electrical noise and stabilize the voltage supplied to the expansion cards. 4. **Gold Fingers:** The edge connector is plated with high-quality gold to ensure low contact resistance and prevent oxidation over long-term industrial use. --- ### Common Applications This part is used primarily in environments where space is constrained or specific hardware layouts are required: * **Industrial PCs (IPC):** Used in 2U rackmount servers where cards must be mounted horizontally to fit the slim case. * **Expansion:** Allowing a single PCIe x4 or x16 slot on a Single Board Computer (SBC) to support two independent PCIe x1 devices (like NICs, sound cards, or I/O controllers). * **Testing Rigs:** Used by engineers to easily access PCIe cards outside of a cramped enclosure. ---
