产品详情资料

 远程底板为700英尺（213米）。未能遵守这些大电缆长度可能会导致PLC系统不稳定运行。2.CPU 350–364多支持七根I/O扩展电缆。CPU 331–341多支持四根I/O扩展电缆。3.50英尺（15米）的I/O总线扩展电缆（IC693CBL302），每端都有一个公接头，其I/O总线端接电阻器内置在电缆的端部接头中。如果使用此电缆，则不会安装单独的终端接线盒。警告：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。可能会导致意外的PLC操作。电缆应用建议一般来说，在可能的情况下，使用标准的工厂制造电缆是有利的，以节省时间并避免布线错误。使用标准电缆当标准长度（0.5、1、2、8或15米）满足需要时，用于连接同一机柜中的底板（CPU和扩展底板之间、两个扩展底板之间或两个远程底板之间）。作为定制点对点电缆的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年7月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–一端有一个公接头，另一端有一条母接头。这些通常与提供Y形连接的IC693CBL300一起使用。
remote baseplate is 700 feet (213 meters). Failure to observe these maximum cable lengths could result in erratic operation of the PLC system. 2. CPUs 350 – 364 support a maximum of seven I/O expansion cables. CPUs 331 – 341 support a maximum of four I/O expansion cables. 3. The 50 foot (15 meter) I/O bus expansion cable (IC693CBL302), which has a male connector on each end, has the I/O bus terminating resistors built into the end connector on the cable. If this cable is used, you would not install a separate terminator block. Caution I/O Bus Expansion cables should NOT be connected or disconnected with power applied to the I/O expansion baseplate(s). Unexpected PLC operation may result. Cable Application Suggestions In general, it is advantageous to use standard, factory-built cables, where possible, to save time and avoid wiring errors. Using Standard CablesFor connecting between baseplates (either between a CPU 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 combination 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 cablesWhen you need a cable length not available in a standard size.When a cable must be routed through a conduit that is not large enough for a standard cable’s connector to fit through. C C-4 Series 90-30 PLC I/O Module Specifications – July 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 male connector on one end and a single female connector on the other end. These are usually used with the IC693CBL300 which supplies the Wye connection.
