I/O扩展系统中可包含的电缆数量为7根，底板和最后一个扩展底板之间的电缆总长度为50英尺（15米）。基板和最后一个远程基板之间的电缆总长度为700英尺（213米）。不遵守这些电缆长度可能导致PLC系统不稳定运行。2.s 350–364支持七条I/O扩展电缆。s 331–341支持四根I/O扩展电缆。3.50英尺（15米）的I/O总线扩展电缆（IC693CBL302），每端都有一个le连接器，其I/O总线终端电阻器内置在电缆的端部连接器中。如果使用此电缆，您将不会安装单独的接线端子块。注意：I/O总线扩展电缆不应与I/O扩展底板的电源连接或断开。意外的PLC操作y结果。电缆应用建议通常，在可能的情况下，最好使用标准的工厂制造电缆，以节省时间并避免布线错误。当标准长度（0.5、1、2、8或15米）适合需要时，使用标准电缆连接同一机柜中的底板（在一个和扩展底板之间、两个扩展底板之间或两个远程底板之间）。作为定制点到点电缆的Y形跳线（IC693CBL300通常用于此）。这种组合节省了时间，因为点对点电缆的构建速度比Y形电缆快得多。如图10-23所示。使用定制电缆当您需要标准尺寸的电缆长度时。当电缆必须通过导管布线时，导管的尺寸不足以容纳标准电缆的连接器。C C-4 Series 90-30 PLC I/O模块规格–2000 GFK-0898F建筑定制长度I/O总线扩展电缆本节提供创建定制长度I/O母线扩展电缆所需的详细信息。两种类型的定制电缆这两种类型是：点对点–一端有一个电缆接头，另一端有一条电缆接头。这些通常与提供Y形连接的IC693CBL300一起使用。这种组合节省了时间，因为点对点电缆的构建速度比Y形电缆快得多。Y形-一端有一个le连接器，另一端有两个连接器（一个le和一个fele）。构建定制长度I/O总线扩展电缆所需的组件：标准Y形电缆上使用的特殊双头Y形连接器可作为单独的组件提供。项目描述电缆：仅限Belden 8107（替代品）：计算机电缆，箔屏蔽上的整体编织，绞合-30伏/80C（176F）24 AWG（.22 mm2）镀锡铜，7 x 32绞合传播速度=70%密耳阻抗=100Ω 25针le连接器：压接插头=安培207464-1；引脚=Amp 66506-9焊接插头=Amp 747912-2 25引脚Fele连接器：压接插座=Amp 207463-2；引脚=Amp 66504-9焊料插座=Amp 747913-2连接器外壳：套件-Amp 745833-5：金属电镀塑料（铜上镍塑料）压接环-Amp 747508-1，开口环套圈=关键信息列出的用户组装电缆的供应商零件号仅供参考，并不建议或暗示首选。
The number of cables that can be included in an I/O expansion system is seven, and the total cable length between the baseplate and the last expansion baseplate is 50 feet (15 meters). The total cable length between the baseplate and the last remote baseplate is 700 feet (213 meters). Failure to observe these cable lengths could result in erratic operation of the PLC system. 2. s 350 – 364 support a of seven I/O expansion cables. s 331 – 341 support a of four I/O expansion cables. 3. The 50 foot (15 meter) I/O bus expansion cable (IC693CBL302), which has a le connector on each end, has the I/O bus termiting resistors built into the end connector on the cable. If this cable is used, you would t install a separate termitor block. Caution I/O Bus Expansion cables should T be connected or disconnected with power applied to the I/O expansion baseplate(s). Unexpected PLC operation y result. Cable Application Suggestions In general, it is adntageous to use standard, factory-built cables, where possible, to save time and avoid wiring errors. Using Standard Cables For connecting between baseplates (either between a and expansion baseplate, between two expansion baseplates or between two remote baseplates) in the same cabinet when a standard length (0.5, 1, 2, 8, or 15 meters) will fit the need. As a Wye jumper for custom built point-to-point cables (IC693CBL300 is often used for this). This combition saves time since a point-to-point cable can be built much faster than a Wye cable. An example of this is shown in Figure 10-23. Using Custom Built cables When you need a cable length t ailable in a standard size. When a cable must be routed through a conduit that is t large eugh for a standard cable’s connector to fit through. C C-4 Series 90-30 PLC I/O Module Specifications – 2000 GFK-0898F Building Custom Length I/O Bus Expansion Cables This section provides details needed to create custom length I/O Bus Expansion cables. Two Types of Custom Built Cables The two types are: Point-to-Point – these have a single le connector on one end and a single fele connector on the other end. These are usually used with the IC693CBL300 which supplies the Wye connection. This combition saves time since a point-to-point cable can be built much faster than a Wye cable. Wye - these have a single le connector on one end and two connectors (one le and one fele) on the other end. Components Needed to Build Custom Length I/O Bus Expansion Cables te: the special two-headed Wye connector used on the standard Wye cables is t ailable as a separate component.
