IS220PAICH1A  可以最大限度地减少或消除大量的插入仪器

IS220PAICH1A是一款在GE Mark VI系列下开发的模拟I/O Pack。单工和三重模块冗余 (TMR) Mark VI 控制系统可用于小型应用和大型集成系统，控制范围从单个模块到多个分布式模块。该系统的吞吐量允许在 40 毫秒内操作多达 9 个 21 插槽 VME 机架的 I/O 板，包括数据投票。在一种称为软件实现容错的方法中，输入在软件中进行投票 (SIFT)。每个控制模块的 VCMI 板通过其自己的 IONet 从控制模块背板和其他模块获取输入。

除了通用 I/O 之外，Mark VI 还拥有许多专为与特定传感器和执行器直接通信而设计的板。在许多情况下，这可以最大限度地减少或消除大量的插入仪器。因此，消除了最关键区域中许多可能的单点故障，从而提高了运行可靠性并降低了长期维护成本。由于与传感器和执行器的直接连接，诊断还可以直接询问设备上的装置，以获得最佳效果。此信息用于评估设备和系统的性能。外围仪表的消除减少了备件库存，这是这种设计的一个微妙的好处。

IS220PAICH1A使用JPDG配电板的配电系统支持冗余馈电的Mark VIe控制电源和冗余馈电的I/O润湿电源。以下是这些连接的具体说明：

•两个24或28 V dc、40 A的控制电源可以使用LG型线束连接到JPDG板。电源连接到主电源。

•可以使用JF型线束将两个24或48 V dc、40 A I/O润湿电源连接到JPDG板。电源连接到主电源。

•一个可选的PPDA模块与JPDG一起用于监测配电系统的健康状况。它使用RD型线束直接连接到I/O连接器JA1和电源连接器JDx。

•JPDG板使用EG型线束从连接器JC1-JC4和JD1-JD5向UCSC Mark VIe控制器和IONet开关提供R、S和T电源。

•JPDG-可使用JB型线束通过J1-J4向多达四个JPDH板供电。

•JPD可以使用EN型线束通过JFA–JFG为多达7个I/O端子板提供I/O润湿电源。

•JPDH板使用RD型线束为多达八个R、S和T（每个）模块扇出控制电源。R、S、T控制电源总线可以使用EH型线束从连接器J1X扩展到另一个JPDH。

•JPDD板可用于将带保险丝的开关式I/O润湿电源分支添加到单个I/O端子板。从JPDG、JFx到JPDD J28，使用JG型线束。

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.
