IS200VSVOH1B用作伺服控制板。該板通過控制四個電動液壓伺服閥來驅(qū)動燃料/蒸汽閥。該板還提供脈率流量輸入、LVDT激勵和LVDT位置反饋。IS200VSVOH1B可用于三冗余系統(tǒng)，也可用于單工系統(tǒng)。
IS200VSVOH1B有一個連接到PCB的單槽前面板。該面板包括一個電纜連接器(J5)以及用于顯示狀態(tài)信息的LED指示燈。前面板上的三個led包括一個運行燈(綠色)、一個故障燈(紅色)和一個狀態(tài)燈。狀態(tài)燈通常不通電。但是，如果出現(xiàn)警報情況，該LED將會通電，并顯示為穩(wěn)定的橙色。
IS200VSVOH1B有六個連接器，包括兩個背板(P1/P2)和四個導電跡線連接器(P3到P6)。)板包括四個繼電器(K1到K4。)這些組件中的每一個在其頂面上都有印刷的圖表。電路板上有電阻、電容和TP測試點。它也有感應器珠(L1-L10。)該板有70多個集成電路。

IS200VSVOH1B is used as servo control board. The board drives the fuel/steam valve by controlling four electro-hydraulic servo valves. The board also provides pulse rate flow input, LVDT excitation, and LVDT position feedback. The IS200VSVOH1B can be used in triple-redundant systems, as well as simplex systems.
The IS200VSVOH1B has a single slot front panel attached to the PCB. The panel includes a cable connector (J5) and LED indicators for displaying status information. The three leds on the front panel include a running light (green), a fault light (red), and a status light. The status light is usually not powered on. However, if there is an alarm situation, the LED will power up and display a stable orange color.
The IS200VSVOH1B has six connectors, including two backplanes (P1/P2) and four conductive trace connectors (P3 to P6). The board consists of four relays (K1 to K4.) Each of these components has a printed chart on its top surface. There are resistance, capacitance and TP test points on the circuit board. It also has sensor beads (L1-L10). The board has more than 70 integrated circuits.
