WOODWARD 9907-1183 數(shù)字調(diào)速器
前面板安裝的第二代用戶可配置蒸汽渦輪數(shù)字調(diào)速器，用于抽汽和進(jìn)氣控制，具有 24Vdc 電源輸入，額定為 Class 1, Div. 2個標(biāo)準(zhǔn)位置。立即升級到下一代即插即用的替代品 505XT。
9907-1183型號設(shè)計用于簡單的單閥蒸汽泵只有基本渦輪機(jī)控制、保護(hù)需要進(jìn)行監(jiān)測。505控制器的集成OCP（操作員控制面板）、超速保護(hù)和跳閘事件記錄器使其成為小型汽輪機(jī)應(yīng)用的理想選擇總體系統(tǒng)成本是一個問題。9907-1183型號設(shè)計用于更復(fù)雜的單閥、單閥抽汽或單進(jìn)汽汽輪機(jī)應(yīng)用需要模擬或離散I/O（輸入和輸出）。可選擇的輸入和輸出可通過以下方式連接到505XT控制器：伍德沃德的LinkNet HT分布式I/O模塊。配置時控制單抽和/或進(jìn)汽式汽輪機(jī)，9907-1183控制器經(jīng)現(xiàn)場驗證的比率限制器功能可確保兩個受控參數(shù)（即速度和速度）之間的相互作用抽汽或入口集管（和抽汽）正確解耦。通過只需輸入水位和渦輪機(jī)的三個點(diǎn)蒸汽圖（工作包線），505XT自動計算所有PID與閥門的比率以及所有渦輪機(jī)的運(yùn)行和保護(hù)限制。
Model 9907-1183 is designed for a simple single valve steam pump and only basic turbine control and protection need to be monitored. The 505 controller's integrated OCP (operator control panel), overspeed protection and trip event recorder make it an ideal choice for small turbine applications. Overall system cost is an issue. The 9907-1183 model is designed for more complex single valve, single valve extrb or single inlet turbine applications requiring analog or discrete I / O (bs and outputs). Selectable bs and outputs can be connected to the 505xt controller through Woodward's bnet HT distributed I / O module. When configured to control single extrb and / or inlet turbines, the 9907-1183 controller's field proven ratio limiter function ensures the interb between two controlled beters (i.e. speed and speed), extrb or inlet header (and extrb) correct decoupling. By bting only the maximum water level and the three-point steam diagram (work envelope) of the turbine, the 505xt automatically calculates the ratio of all PID to valves and the operation and protection limits of all turbines.
