7400209-010 I/O 总线 三重 I/O 总线以每秒 375 kb 的速度在 I/O 模块和主处理器之间传输数据。
三重I/O总线沿背板底部传输。I/O 总线的每个通道在三个主处理器之一和 I/O 模块上的相应通道之间运行。
I/O 总线可以使用一组三根 I/O 总线电缆在机箱之间扩展。
通信总线
通信 （COMM） 总线在主处理器和通信模块之间以每秒 2 兆比特的速度运行。机箱的电源分布在背板中心下方的两个独立电源轨上。
机箱中的每个模块都通过双电源调节器从两个电源轨获取电力。每个输入和输出模块上有四组电源稳压器：一组用于通道 A、B 和 C，另一组用于状态指示 LED 指示灯。
The triple I/O bus transfers data between the I/O module and the main processor at a speed of 375 kb per second.
The triple I/O bus is transmitted along the bottom of the backplane. Each channel of the I/O bus runs between one of the three main processors and the corresponding channel on the I/O module.
The I/O bus can be extended between chassis using a set of three I/O bus cables.
Communication bus
The communication (COMM) bus runs at a speed of 2 megabits per second between the main processor and the communication module. The power supply of the chassis is distributed on two independent power rails below the center of the backplane.
Each module in the chassis receives power from two power rails through a dual power regulator. There are four sets of power regulators on each input and output module: one for channels A, B, and C, and the other for status indicator LED indicators.
