TC-501-02-4M5 Trusted®输入/输出(I/O)电缆

本文档提供SmartSlot组中可用的Trusted®输入/输出(I/O)电缆类型的详细信息。这些类型的电缆提供连接设施之间的
可信模拟和数字输入/输出模块，以及可信现场终端组件(FTAs)或可信通用现场终端组件(VFTAs)。电缆也可以在一端带有“飞引线”，以便连接到条件端子。
目前可用的可信I/O smartlot电缆类型列在第4页的表1中。
电缆是根据用户要求制造的，因此必须指定电缆绝缘的长度和类型。长度必须以xmx格式指定到最接近0.5 m，例如，对于长度为2.0 m的电缆，必须指定为2m0。此细节必须添加到零件号的末尾。请注意，一些电缆长度是首选选项，可能更容易获得;详情请参阅罗克韦尔自动化。电缆绝缘类型是电缆部件号的一部分，用02表示
低烟零卤(LSZH)或03 UL认证电缆材料。02也是IEC 60332-3 a类阻燃电缆，在订购电缆时，建议用户提供如表1所示的详细信息。
建议I/O线缆长度不超过15m。如果有必要，可以指定比这更长的电缆，但可能会受到电压下降，偏移，串扰和噪声的影响，并且会出现材料处理问题。
内部电缆是为连接在相邻机箱中的电缆而设计的。如果线缆需要离开机箱环境，外部线缆具有更强的保护。请注意，“外部”电缆没有铠装，不适合真正的外部使用，仍然必须小心处理。这些电缆在通过电缆路线时需要保护，也不应该被连接器拉出。它们应该通过运输/压缩块进入机柜，不能被挤压。

This document provides detailed information for the types of Trusted® input/output (I/O) Cables available within the SmartSlot group. These types of cable provide connection facilities between the
Trusted analogue and digital input/output modules, and Trusted Field Termination Assemblies (FTAs) or Trusted Versatile Field Termination Assemblies (VFTAs) as required. Cables are also available with a ‘flying lead’ at one end to allow connection to conditioned terminals.
The types of Trusted I/O SmartSlot Cables currently available are listed in Table 1 on page 4.
The cables are manufactured to user’s requirements, therefore length and type of cable insulation must be specified. Length must be specified to the nearest 0.5 m in the format xmx, e.g. 2m0 for a cable length of 2.0 m. This detail must be added to the end of the part number. Note that some cable lengths are preferred options and may be easier to obtain; refer to Rockwell Automation for details. The type of cable insulation forms part of the cable part number and is denoted by 02 for
Low Smoke Zero Halogen (LSZH) or 03 for UL Certified cable material. 02 is also flame retardant to IEC 60332-3 Cat A. When ordering cables, it is recommended that the user supplies the details as shown in Table 1.
The maximum recommended I/O cable length is 15 m. Cables longer than this may be specified if necessary but may suffer from voltage drop, offset, crosstalk and noise and will present materials handling problems.
Internal cables are designed for cables where they are terminated in adjacent enclosures. If the cable needs to leave the enclosure environment, the external cable has more protection. Note that the ‘external’ cables are not armoured and are not suitable for truly external use and must still be treated with care. These cables will need protection when drawn through a cable route, and should also not be pulled by the connector(s). They should enter cabinets through transit/compression blocks and cannot be glanded.
