dSPACE Simulator Mid-Size是一種閉環的硬件在環仿真器，其有以下特性：

• 支持信號調理

• 支持給ECU提供等效或真實負載

• 失效模擬

• 兩路電壓系統支持遠程控制供電

主機需配備一塊鏈接板卡-Link Board來進行總線接口連接。dSAPCE提供3種不同類型的Link Board來匹配主機不同的總線類型（有ISA/PCI/PCMIA接口）。總線接口用來將real-time model下載到仿真器中，對仿真過程進行控制。主機和仿真器之間通過RS232串口來控制故障注入單元(FIU).

dSPACE Mid-Size仿真包含以下部件:

• 處理器板塊DS1005/DS1006

• I/O板卡DS2211/DS2202

• 鏈接板卡DS814

• Load/FIU單元：5個DS790負載板卡，每個板卡包含10個通道，可配置低功率的阻性或感性負載；5個DS791故障注入單元，每個單元包含10個通道，可配置低功率的阻性或感性負載

• 一個DS686?Backplane

• 一個DS685 Midplane

• 可遠程控制的供電單元

Loads are installed on the load cards inside the simulator or plugged to the panel on the front of the simulator. Inside the simulator there are load sockets that the loads can be connected to. One load socket connects the load to the ECU channel, the other load socket connects the load to a high rail or to the adjacent channel (for double-ended loads).

負載安裝在模擬器內部的負載卡上，或插入模擬器正面的面板上。在模擬器內部，有負載插座，負載可以連接到。一個負載插座將負載連接到ECU通道，另一個負載插座將負載連接到高軌或相鄰通道（用于雙端負載）。
