SPA-ZC22 线连接模块

Description

总线连接模块用作 SPACOM 设备和光纤 SPA 总线之间的连接装置

SPA-ZC 22 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。

SPA-ZC 22 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。

SPA-ZC22 线连接模块

The bus connection module serves as the connection device between the SPACOM device and the fiber optic SPA bus

The SPA-ZC 22 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 SPA-ZC 22 comes with a 9-pin Type D miniature connector for RS 485 or SPA connections, a 25-pin type D connector available for order, and two or five fiber optic connector sets for optical 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.
