25针母d型10槽I/O总线扩展底板，IC693CHS392J，有几种用途。它基本上用作PLC本地机箱，但也可用于将I/O扩展到附近不超过50英尺(15米)的其他位置(称为本地I/O扩展)。本地I/O扩展允许用户增加PLC的I/O，并在单个处理器的监控下增强控制。底板上没有CPU。本地I/O扩展对于I/O位于本地机箱附近的小型PLC系统来说是一个很好的选择。

IC693CHS392J扩展底板的右端安装有一个25针母头d型I/O总线扩展连接器。此连接器用于与其他底板连接。它有10个槽，按顺序从1到10标记。底板不能单独存在。它必须安装在具有CPU的系统的CPU底板中，无论是在PLC中还是在具有个人计算机接口(PCI)卡的个人计算机中。第一个扩展底板通过一条短并行电缆连接到CPU底板，该电缆在CPU底板和本地扩展的I/O底板之间提供无缝并行数据传输。CPU的类型决定了系统中可安装的扩展底板的数量。cpu 331、340和341最多支持4个底板，而cpu 350及以上最多支持7个底板。电源必须提供给扩展底板，并且必须根据底板的模块以及将放在每个底板电源上的本地负载进行计算。

25-pin female D-type 10-slot I/O bus expansion backboard, IC693CHS392J, has several uses. It is basically used as a PLC local chassis, but can also be used to expand I/O to other locations not more than 50 feet (15 m) nearby (called local I/O expansion). Local I/O scaling allows users to increase the I/O of the PLC and enhance control under the supervision of a single processor. There is no CPU on the mainboard. Local I/O extension is a good option for small PLC systems where the I/O is located near the local chassis.

A 25-pin female D-type I/O bus expansion connector is installed at the right end of the IC693CHS392J expansion base plate. This connector is used to connect to other baseboards. It has 10 slots, marked in order from 1 to 10. The baseplate cannot exist alone. It must be installed in the CPU baseboard of a system with a CPU, either in a PLC or in a personal computer with a Personal computer interface (PCI) card. The first extended backboard is connected to the CPU backboard via a short parallel cable that provides seamless parallel data transfer between the CPU backboard and the locally extended I/O backboard. The type of CPU determines the number of expansion backboards that can be installed in the system. Cpus 331, 340, and 341 support up to four backboards, while cpus 350 and above support up to seven backboards. Power must be supplied to the expansion baseboard and must be calculated based on the modules of the baseboard and the local load that will be placed on each baseboard power supply.
