　　型號類型 模擬 I/O 包

　　無害認(rèn)證 UL E207865

　　電源 最小 27.4 VDC、標(biāo)稱 28.0 VDC 和最大 28.6 VDC

　　IS220PAICH1A 是一款在GE Mark Vl系列下開發(fā)的模擬I/O Pack。單工和三重模塊冗余(TMR)Mark V 控制系統(tǒng)可用于小型應(yīng)用和大型集成系統(tǒng)，控制范圍從單個(gè)模塊到多個(gè)分布式模塊。該系統(tǒng)的吞吐量允許在 40 毫秒內(nèi)操作多達(dá) 9個(gè) 21 插槽 VME 機(jī)架的 I/0 板，包括數(shù)據(jù)投票。在一種稱為軟件實(shí)現(xiàn)容錯的方法中，輸入在軟件中進(jìn)行投票(SIFT)。每個(gè)控制模塊的 VCMI 板通過其自己的 IONet 從控制模塊背板和其他模塊獲取輸入。

　　除了通用 I/0 之外，Mark V 還擁有許多專為與特定傳感器和執(zhí)行器直接通信而設(shè)計(jì)的板。在許多情況下，這可以最大限度地減少或消除大量的插入儀器。因此，消除了最關(guān)鍵區(qū)域中許多可能的單點(diǎn)故障，從而提高了運(yùn)行可靠性并降低了長期維護(hù)成本。由于與傳感器和執(zhí)行器的直接連接，診斷還可以直接詢問設(shè)備上的裝置，以獲得最佳效果。此信息用于評估設(shè)備和系統(tǒng)的性能。外圍儀表的消除減少了備件庫存，這是這種設(shè)計(jì)的一個(gè)微妙的好處。

　　The IS220PAICH1A is an analog I/O Pack developed under the GE Mark Vl series. Simplex and Triple Module Redundancy (TMR)Mark V control systems can be used in small applications and large integrated systems, with control ranging from a single module to multiple distributed modules. The system's throughput allows the operation of up to nine I/0 boards of a 21-slot VME rack in 40 milliseconds, including data voting. In an approach called software Implementation Fault tolerance, input votes in software (SIFT). Each control module's VCMI board receives input from the control module backplane and other modules through its own IONet.

　　In addition to the universal I/0, the Mark V has a number of boards designed for direct communication with specific sensors and actuators. In many cases, this minimizes or eliminates a large number of inserted instruments. As a result, many possible single points of failure in the most critical areas are eliminated, improving operational reliability and reducing long-term maintenance costs. Thanks to the direct connection to the sensors and actuators, diagnostics can also be directly queried on the device for optimal results. This information is used to evaluate the performance of devices and systems. The elimination of peripheral meters reduces spare parts inventory, which is a subtle benefit of this design
