IC693CBL302 总线   I/O 总线扩展电缆

【产品详情】

GE Fanuc IC693CBL302 是专门用于 90-30 系列系统的 I/O 总线扩展电缆。也称为星形电缆，该电缆是该系列中特别特别的电缆，因为它在电缆的两端都配备了一个公连接器。每个公连接器都是一个 25 针 D 连接器。连接到扩展底板的头部是端接的公连接器。 IC693CBL302允许用户将I/O总线扩展到系统内的远程或扩展底板。请记住，IC693CBL302是为 Sereis 90-30 系统设计的。如果系统需要更多 I/O 插槽，或者底板必须远离 CPU 底板，则需要使用星形电缆。

这条 50 英尺长的电缆还具有 I/O 总线终端电阻器，这些电阻器内置于电缆末端的连接器中。因此，用户在使用此电缆时无需在其系统中安装单独的终端块。在只有一个扩展底板的系统中，用户可以使用此电缆端接I/O总线。这些端接电阻将端接I/O总线。 在单个 I/O 扩展系统中最多可以使用七根星形电缆一次可以有。CPU 底板和最后一个扩展底板之间的电缆总长度必须小于 50 英尺（15 米）。 当 I/O 扩展底板通电时，连接或断开电缆从来都不安全。始终断开底板与电源的连接，以连接或断开电缆，例如IC693CBL302。

IC693CBL302电缆是一种已制造的 I/O 扩展电缆，其主要用途是互连可编程逻辑控制器或 PLC 系统中的不同底板和扩展端口。这种特殊的扩展电缆已包含在GE Fanuc公司制造的PLC组件的90-30系列中。该电缆旨在用作PLC系统中链路的最后一根电缆。此电缆不能用作星形电缆。GE Fanuc IC693CBL302 I/O 扩展电缆的长度为 15 米，它包括一个用于连接到 CPU 底板端的单公连接器，并且在扩展底板端还有一个单端接公连接器。

GE Fanuc IC693CBL302 I/O 扩展电缆专门用于避免使用不同长度的电缆到达特定距离的底板。它是 PLC 中最后一个扩展底板允许的最大长度。CPU 底板和最后一个远程底板之间的最大电缆总长度为 213 米。如果未正确计算这些距离，则在操作过程中可能会出现错误，包括信号传输失败或不稳定。GE Fanuc IC693CBL302 I/O 扩展电缆在末端连接器中内置了 I/O 总线终端电阻器。根据 CPU 类型，电缆数量可能会有所不同，编号从 350 到 374 额定值的 CPU 最多支持 7 条不同的电缆，编号从 331 到 341 的 CPU 最多支持 4 根扩展电缆。连接或断开这些电缆时，不得向系统通电，否则可能会对系统造成不可逆转的损坏。

【英文介绍】

The GE Fanuc IC693CBL302 is an I/O bus expansion cable specifically designed for use in 90-30 series systems. Also known as the star cable, this cable is a particularly special cable in the series because it is equipped with a male connector at both ends of the cable. Each male connector is a 25-pin D connector. The heads attached to the expansion baseplate are terminated male connectors. The IC693CBL302 allows users to extend the I/O bus to remote or extended backboards within the system. Keep in mind that the IC693CBL302 is designed for Sereis 90-30 systems. If the system requires more I/O slots, or the backplane must be located away from the CPU backplane, you need to use a star cable.

The 50-foot cable also features I/O bus terminal resistors that are built into connectors at the end of the cable. Therefore, users do not need to install a separate terminal block in their system when using this cable. In a system with only one expansion backboard, the user can use this cable to end the I/O bus. These end resistors will end the I/O bus. Up to seven star cables can be used in a single I/O expansion system at a time. The total length of the cable between the CPU baseboard and the last expansion baseboard must be less than 50 feet (15 meters). When the I/O expansion baseplate is energized, it is never safe to connect or disconnect a cable. Always disconnect the baseboard from the power supply to connect or disconnect the cable, such as IC693CBL302.

The IC693CBL302 cable is a manufactured I/O expansion cable whose primary purpose is to interconnect different baseboards and expansion ports in a programmable logic controller or PLC system. This special expansion cable is included in the 90-30 series of PLC assemblies manufactured by GE Fanuc. The cable is intended to be used as the last cable of the link in a PLC system. This cable cannot be used as a star cable. The GE Fanuc IC693CBL302 I/O expansion cable has a length of 15 meters and includes a single male connector for connection to the CPU baseboard end and a single terminated male connector at the extension baseboard end.

The GE Fanuc IC693CBL302 I/O expansion cable is specifically designed to avoid the use of cables of different lengths to reach specific distances on the baseboard. It is the maximum length allowed for the last extended baseboard in the PLC. The maximum total cable length between the CPU backboard and the last remote backboard is 213 meters. If these distances are not calculated correctly, errors may occur during operation, including failed signal transmission or instability. The GE Fanuc IC693CBL302 I/O expansion cable has an I/O bus terminal resistor built into the end connector. The number of cables may vary depending on the CPU type, with cpus numbered from 350 to 374 ratings supporting up to seven different cables, and cpus numbered from 331 to 341 supporting up to four expansion cables. When connecting or disconnecting these cables, do not power the system, otherwise it may cause irreversible damage to the system.
