TRICONEX 3625C1 英维思SIS模块 冗余系统

3625C1 通信（COMM）总线以每秒2兆比特的速度在主处理器和通信模块之间运行。机箱的电源分布在背板中心的两个独立电源导轨上。机箱中的每个模块都通过双电源调节器从两个电源导轨获取电源。每个输入和输出模块上有四套功率调节器：一套用于通道A、B和C，一套用于状态指示LED指示灯。 

每个I/O模块通过其相关的现场终端组件向现场传输信号或从现场传输信号。机箱中的两个位置作为一个逻辑插槽连接在一起。第一个位置固定活动I/O模块，第二个位置固定热备用I/O模块。3625C1终端电缆连接到背板的顶部。每个连接都从端接模块延伸到活动和热备用I/O模块。因此，有源模块和热备用模块都从现场终端接线接收相同的信息。

Tricon 3625C1支持两种基本类型的数字输入模块：TMR和单个。以下段落介绍了数字输入模块的一般情况，随后介绍了TMR和单个模块的具体情况。每个数字输入模块都包含三个相同通道（A、B和C）的电路。

The 3625C1 Communication (COMM) bus runs at 2 megabits per second between the main processor and the communication module. The power supply of the chassis is distributed on two independent power guide rails in the center of the backplane. Each module in the case receives power from two power rails via dual power regulators. There are four power regulators on each input and output module: one for channels A, B and C, and one for the status indicator LED indicator.

Each I/O module transmits signals to or from the field through its associated field terminal components. The two positions in the case are connected together as a logical slot. The first position holds the active I/O module and the second position holds the hot standby I/O module. 3625C1 Terminal cable is connected to the top of the backplane. Each connection extends from the termination module to the active and hot standby I/O modules. Therefore, both the active module and the hot standby module receive the same information from the field terminal wiring.

The Tricon 3625C1 supports two basic types of digital input modules: TMR and single. The following paragraphs describe the digital input modules in general, followed by the details of TMR and individual modules. Each digital input module contains three circuits with the same channels (A, B, and C).
