模块化设计允许灵活安装。一个T型DIN导轨是所有你需要安装电源/控制器载体到位。I/O接口载波插入到电源/控制器载波上。只需将您的I/O终端块插入载波。
DeltaV系统的模块化设计方法允许您根据需要添加I/O载波。
允许您在线扩展。额外的8宽载波可以根据需要在线添加。载波扩展器使您能够灵活地在多行中安装I/O载波，每行安装1、2、3或4个载波。
一体化配电。将控制器和I/O接口配电集成到载波中，减少和简化电源和接地。载波还集成了屏蔽接地排，以隔离和排水场噪声远离系统电源

I/O接口载波插入到电源/控制器载波上。电源/控制器载波提供系统电源和I/O接口与控制器之间的通信。控制器处理I/O接口信息。需要一个额外的电源/控制器载波与冗余控制器一起使用。
将接口载体安装在t型DIN导轨上。I/O接口载体包括用于批量24v DC现场仪表电源、I/O接口和端子排的连接。
每个I/O接口载波都配备了一个连接器，该连接器允许将额外的I/O接口载波插入到其上。
单个I/O子系统最多支持8个8宽I/O接口载波上的64个I/O接口。对于水平安装解决方案，1宽的本地总线扩展器允许您在不同的载波上继续I/O总线。有两种类型的8-wide I/O接口载波可用。它们都在载体顶部有现场电源连接器。原始载波将每组现场电源终端连接到两个I/O卡，另一个选项每个卡槽都有单独的现场电源，如果冗余I/O卡需要单独的现场电源，则是理想的。

Modular design allows flexible installation. A T- type DIN rail is all you need to mount the power/controller carrier into place. The I/O interface carrier plugs on to the power/controller carrier. Simply plug your I/O terminal blocks into the carrier.
The DeltaV system’s modular design approach allows you to add I/O carriers as you need them.
Allows you to expand online. Additional 8-wide carriers may be added online as desired. Carrier extenders give you the flexibility to install I/O carriers in multiple rows with 1,2, 3 or 4 carriers per row.
Integrated power distribution. Controller and I/O interface power distribution is integrated into the carriers to reduce and simplify power and grounding. Carriers also have integrated shield ground bar to isolate and drain field noise away from system power

The I/O interface carrier plugs on to the power/controller carrier. The power/controller carrier supplies the system power and communications between the I/O interfaces and the controller. The controller processes the I/O interface information. An additional power/controller carrier is required for use with redundant controllers.
Mount your interface carrier on a T-type DIN rail. The I/O interface carrier includes the connections for the bulk 24 V DC field instrument power, I/O interfaces, and terminal blocks.
Each I/O interface carrier is equipped with a connector that allows an additional I/O interface carrier to be plugged on to it.
Up to 64 I/O interfaces on eight 8-wide I/O interface carriers are supported by a single I/O subsystem. For the horizontal-mount solution, 1-wide local bus extenders allow you to continue the I/O bus on a different row of carriers. There are two types of 8-wide I/O interface carriers available. They both have connectors for field power on the top of the carrier. The original carrier connects each set of field power terminals to two I/O cards, and the other option have individual field power per card slot and is ideal if separate field power is required for redundant I/O cards.
