SPAZC22AM 总线连接模块

总线连接模块用作SPAZC22AM 设备和光纤 SPA 总线之间的连接装置

SPAZC22AM 总线连接模块将 SPA 总线的光信号转换为 RS 485、SPA（+5 V）或 RS 232 信号，反之亦然。总线连接模块内置电源模块。在进行检修时，该内置电源模块可将SPACOM 设备从总线连接模块上断开，而不需要中断通过光纤回路进行的数据通信。

SPAZC22AM 配有一个用于 RS 485 或 SPA 连接的 9 针 D 型微型连接器，一个可供订购的 25 针 D 型连接器，两个或五个用于光缆的光纤连接器组。光纤链路可以是玻璃纤维电缆、塑料芯电缆或两者混用。

总线连接模块安装在设备柜中的适当位置，模块的连接电缆连接到 SPACOM 设备后面板上的 D 型连接器。SPA-ZC 22 型总线连接模块可连接到任何配备 D 型连接器的SPACOM 设备。总线连接模块还可以连接到通信系统的主单元，如变电站级单元 SACO 148D4 和 SRIO 1000M。

SPAZC22AM 总线连接模块

The bus connection module is used as the connection device between the SPAZC22AM device and the fiber optic SPA bus

The SPAZC22AM bus connection module converts optical signals from the SPA bus to RS 485, SPA (+5 V) or RS 232 signals and vice versa. Bus connection module Built-in power module. The built-in power module disconnects SPACOM devices from the bus connection module during an overhaul without interrupting data communication through the fiber optic loop.

The SPAZC22AM comes with a 9-pin Type D miniature connector for RS 485 or SPA connections, a 25-pin Type D connector available on order, and two or five fiber optic connector sets for fiber optic cables. Fiber optic links can be glass fiber cables, plastic core cables, or a combination of both.

The bus connection module is installed in the appropriate position in the device cabinet, and the module’s connection cable connects to the D-connector on the rear panel of the SPACOM device. The SPA-ZC Type 22 bus connection module can be connected to any SPACOM device equipped with a Type D connector. The bus connection module can also be connected to the main units of the communication system, such as the substance-level units SACO 148D4 and SRIO 1000M.
