現(xiàn)場(chǎng)終端單元（FTU）是輸入/輸出模塊的一部分，用于
將所有三個(gè)FIU連接到單個(gè)現(xiàn)場(chǎng)設(shè)備。FTU主要包括
前端信號(hào)調(diào)節(jié)、現(xiàn)場(chǎng)信號(hào)所需的無源元件
過壓保護(hù)和EMI/RFI濾波。當(dāng)安裝在受信任的
控制器或擴(kuò)展器機(jī)箱，F(xiàn)TU現(xiàn)場(chǎng)連接器互連至
連接在機(jī)箱后部的輸入/輸出電纜組件。
SmartSlot鏈接通過從HIU傳遞到現(xiàn)場(chǎng)連接
FTU。這些信號(hào)直接傳輸至輸入/輸出電纜組件并進(jìn)行維護(hù)
與FTU上的輸入/輸出信號(hào)隔離。SmartSlot鏈接是智能的
活動(dòng)和備用模塊之間的連接，以便在
模塊更換。
現(xiàn)場(chǎng)接口單元（FIU）是模塊的一部分，包含
與特定類型的現(xiàn)場(chǎng)輸入/輸出接口所需的特定電路
信號(hào)。每個(gè)模塊有三個(gè)FIU，每個(gè)片一個(gè)。對(duì)于TMR 24 Vdc數(shù)字
輸入模塊，F(xiàn)IU包含一個(gè)單獨(dú)的模數(shù)（A/D）轉(zhuǎn)換器
對(duì)于40個(gè)現(xiàn)場(chǎng)輸入中的每一個(gè)。
FIU從HIU接收邏輯隔離電源。金融情報(bào)室提供
針對(duì)
FIU電路。一個(gè)隔離的6.25 Mbit/s串行鏈路將每個(gè)FIU連接到
HIU切片。
FIU還測(cè)量一系列機(jī)載“內(nèi)務(wù)”信號(hào)，以協(xié)助
監(jiān)控模塊的性能和運(yùn)行條件。
這些信號(hào)包括電源電壓、電流消耗、車載
參考電壓和電路板溫度。Upon receiving your QuickPanel+ operator interface carefully inspect all shipping containers for damage. If any part of the system is damaged, notify the carrier immediately. The damaged shipping container should be saved as evidence for inspection by the carrier. As the consignee, it is your responsibility to register a claim with the carrier for damage incurred during shipment. However, we will fully cooperate with you should such action be necessary. After unpacking the unit, record all serial numbers. Serial numbers are required if you need to contact Customer Care during the warranty period. Shipping containers and packing material should be saved in case it is necessary to transport or ship the unit. Verify that all components of the system have been received and that they agree with your order. If the system received does not agree with your order, contact Customer Care (see “Contact Information” for phone numbers and email addresses). Before you attempt to power up the operator interface for the first time, inspect the unit for loose or damaged components. If damage is found (for example, in the form of bent component leads or loose components), contact GE Intelligent Platforms for additional instructions. Do not apply power to the unit if it has visible damage. Applying power to a unit with damaged components could cause additional damage.
