IS220PAICH1A? 可以最大限度地減少或消除大量的插入儀器

IS220PAICH1A是一款在GE Mark VI系列下開發(fā)的模擬I/O Pack。單工和三重模塊冗余 (TMR) Mark VI 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/O 板，包括數(shù)據(jù)投票。在一種稱為軟件實(shí)現(xiàn)容錯(cuò)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/O 之外，Mark VI 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(zhǎng)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(píng)估設(shè)備和系統(tǒng)的性能。外圍儀表的消除減少了備件庫(kù)存，這是這種設(shè)計(jì)的一個(gè)微妙的好處。

IS220PAICH1A使用JPDG配電板的配電系統(tǒng)支持冗余饋電的Mark VIe控制電源和冗余饋電的I/O潤(rùn)濕電源。以下是這些連接的具體說明：

?兩個(gè)24或28 V dc、40 A的控制電源可以使用LG型線束連接到JPDG板。電源連接到主電源。

?可以使用JF型線束將兩個(gè)24或48 V dc、40 A I/O潤(rùn)濕電源連接到JPDG板。電源連接到主電源。

?一個(gè)可選的PPDA模塊與JPDG一起用于監(jiān)測(cè)配電系統(tǒng)的健康狀況。它使用RD型線束直接連接到I/O連接器JA1和電源連接器JDx。

?JPDG板使用EG型線束從連接器JC1-JC4和JD1-JD5向UCSC Mark VIe控制器和IONet開關(guān)提供R、S和T電源。

?JPDG-可使用JB型線束通過J1-J4向多達(dá)四個(gè)JPDH板供電。

?JPD可以使用EN型線束通過JFA–JFG為多達(dá)7個(gè)I/O端子板提供I/O潤(rùn)濕電源。

?JPDH板使用RD型線束為多達(dá)八個(gè)R、S和T（每個(gè)）模塊扇出控制電源。R、S、T控制電源總線可以使用EH型線束從連接器J1X擴(kuò)展到另一個(gè)JPDH。

?JPDD板可用于將帶保險(xiǎn)絲的開關(guān)式I/O潤(rùn)濕電源分支添加到單個(gè)I/O端子板。從JPDG、JFx到JPDD J28，使用JG型線束。

IS220PAICH1A? 可以最大限度地減少或消除大量的插入儀器

The IS220PAICH1A is an analog I/O Pack developed under the GE Mark VI series. Simplex and Triple Module Redundancy (TMR) Mark VI 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/O boards of a 21-slot VME rack, including data voting, in 40 milliseconds. 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 general purpose I/O, the Mark VI 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.

The power distribution system of the IS220PAICH1A using the JPDG switchboard supports the redundant fed Mark VIe control power supply and the redundant fed I/O wetting power supply. The following are specific descriptions of these connections:

? Two 24 or 28 V dc, 40 A control power supplies can be connected to the JPDG board using the LG-type harness. Power supply is connected to the main power supply.

Two 24 or 48 V dc, 40 A I/O wetting power supplies can be connected to the JPDG board using a JF type harness. Power supply is connected to the main power supply.

An optional PPDA module is used in conjunction with JPDG to monitor the health of the power distribution system. It uses an RD-type harness to connect directly to the I/O connector JA1 and the power connector JDx.

? The JPDG board uses EG type wiring harnesses to supply R, S, and T power from connectors JC1-JC4 and JD1-JD5 to the UCSC Mark VIe controller and IONet switches.

JPDG- Power can be supplied to up to four JPDH boards via J1-J4 using JB-type wiring harnesses.

JPD can provide I/O wetting power to up to 7 I/O terminal boards via JFA-JFG using EN type harness.

? The JPDH board uses RD-type wiring harnesses to fan out control power for up to eight R, S and T modules (each). The R, S, T control power bus can be extended from the connector J1X to another JPDH using the EH harness.

?JPDD boards can be used to add switching I/O wetted power branches with fuses to a single I/O terminal board. From JPDG, JFx to JPDD J28, JG harness is used.
