　　IS220PAICH1A 是一款在GE Mark Vl系列下开发的模拟I/O Pack。单工和三重模块冗余(TMR)Mark V 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/0 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/0 之外，Mark V 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。

　　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
