TK-ODD321  C200E控制处理器

CIOM-A (Chassis Input/Output Modules-Series A)是一个基于机箱的平台。模块以单宽和双宽形式存在。模块已插入机箱槽位;单宽模块占用1个槽位，双宽模块占用2个槽位。作为一个平台，机箱不仅承载I/O模块，还承载执行其他功能的模块。
一些例子包括:
C200E控制处理器
•RM (Redundancy Module)
电池扩展模块
·控制网络接口模块(CNI)
•以太网模块
I/O模块是本文的重点。其他模块类型将在单独的规范文档中介绍。图2-1 Experion机箱系列
权力
模块电源由a系列专用电源供电。电源有冗余和非冗余配置。电源模块位于机箱左侧，不占用机箱槽位。电源为插入机箱的模块提供直流电源。现场供电由单独的(外部)电源提供。
a系列机箱类型
机箱的不同之处在于所提供的机箱可以容纳的模块位置或插槽数量。机箱有五个版本(4、7、10、13和17个插槽)。一些模块是双宽的，将使用两个机箱位置。
型号约定(TC和TK)
所有型号前面都有TC-或TK-。TC指示器表示该模块未进行保形涂层，TK指示器表示该模块已进行保形涂层。除此之外，模块是相同的。
支持的控制处理器所有的cim – a I/O模块都可以与C200E控制处理器一起使用。

Chassis Input/Output Modules-Series A (CIOM-A) is a chassis based platform. Modules exist in a single-wide and double-wide form factor. Modules are inserted into chassis slot positions; single-wide occupy one slot position while double-wide modules occupy two slots. As a platform, the chassis is host to not only I/O modules, but modules that perform other functions.
Some examples include:
 C200E Control Processor
 Redundancy Module (RM)
 Battery Extension Module
 ControlNet Interface Module (CNI)
 Ethernet Module
The I/O modules are the focus of this document. Other module types are covered in separate Specification documents. Figure 2-1 Experion Chassis Series
Power
Module power is supplied by a Series-A specific power supply. Power suppliers are available in a redundant and nonredundant configuration. The power module plugs to the left side of each chassis and does not consume a chassis slot position. The power supply provides DC power for the modules inserted into the chassis. Field power is provided by separate (external) power supplies.
Series-A Chassis Types
Chassis differ by the number of module positions or slots that the given chasses can accommodate. Chassis come in five versions (4, 7, 10, 13, and 17 slot). Some modules are double-wide and will use two chassis positions.
Model Number Conventions (TC and TK)
All model numbers are preceded by a TC- or a TK-. The TC designator indicates that the module is not conformal coated while the TK designator indicates that the module has conformal coating applied. Aside from this the modules are identical.
Supported Control Processors All CIOM-A I/O modules are usable with the C200E control processor.
