HONEYWELL ACX631電源模塊
過壓停機如果操作條件導致輸出電壓過高，則會自動停機。發生過電壓關機后，必須中斷輸入電源以重新建立輸出。停機原因消除后，停機電路在輸入電源斷開后不到30秒內復位。第2部分，2區應用電源作為恒壓電源運行，具有規范中列出的最大額定負載。如果在額定25°C負載下，負載電流試圖超過最大電流的110%，輸出電壓開始向零下降，從而限制輸送到負載的電流。過載消除后，恢復正常運行。外部現場設備的功率標準200系列子系統中所需的實際功率取決于正在通電的FBM/現場總線通信模塊（FCM）/現場控制處理器（FCP）的數量、使用的終端組件的類型，以及單個現場設備是使用內部電源還是外部電源。FPS400-24還可用作現場電源，為外部現場設備供電。然而，為了系統的完整性，現場設備和DIN導軌基板不應使用相同的FPS400-24供電。包裝堅固的襯墊設計有助于減少維護，因為外殼是密封的，沒有風扇磨損。密封墊圈設計還為腐蝕性環境提供保護，如硫化氫和氯，如在許多過程控制裝置中發現的。電源有一個DIN導軌安裝支架，用于安裝在水平或垂直DIN導軌上。支架可以旋轉以進行水平或垂直DIN導軌安裝，也可以拆卸以進行電源的壁裝

Overvoltage Shutdown
Automatic shutdown occurs if operating conditions cause excessive output voltage. After the occurrence of an overvoltage shutdown, input power must be interrupted to re-establish the output. After the cause of the shutdown has been removed, the shutdown circuit resets in less than 30 seconds after the removal of input power. Division 2, Zone 2 Application The power supply operates as a constant voltage source with maximum load ratings as listed in the specifications. If load current attempts to exceed greater than 110% of maximum current at the rated 25°C load, the output voltage begins to decrease toward zero, thereby limiting the current delivered to the load. Upon removal of overload, normal operation resumes. Power for External Field Devices The actual amount of power required in a standard 200 Series subsystem depends on the number of FBMs/Fieldbus Communication Modules (FCMs)/Field Control Processors (FCPs) being powered, the types of termination assemblies used, and whether internal or external powering is used for the individual field device(s). The FPS400-24 can also be used as a field power supply to power external field devices. However, for system integrity field devices and DIN rail baseplates should not be powered from the same FPS400-24. Packaging The robust gasketed design lends itself to minimal maintenance because the housing is sealed and there are no fans to wear out. The sealed gasketed design also provides protection for corrosive atmospheres such as hydrogen sulfides and chlorine, as found in many process control plants. The power supply has a DIN rail mounting bracket for mounting on a horizontal or vertical DIN rail. The bracket can be rotated for horizontal or vertical DIN rail mounting or removed for wall mounting of the power supply
