BENTLY 128275-01-E PLC自动化备件

3500系统现已满足可靠性要求，可以使用过程失效分析的结果更好地决定所需的3500的配置，各种选项包括:

1.标准系统

2.带冗余电源的标准系统

3.带单一传感器输入(TMRI/O: 母线制)和单一末级元件的TMR3500框架。

4.带单一传感器输入(TMRI/O: 母线制)和TMR末级元件的TMR3500框架。

5.带三重传感器输入(TMRI/O: 分立)和单一末级元件的TMR3500框架。

6.带三重传感器输入(TMR1/O: 分立)和TMR末级元件的TMR3500框架。

为作为TMR系统运行，3500 监测系统必须安装以下模块:

①一个TMR型式的框架接口模块

②两个电源(如果其中一个发现有故障，另一个电源可无间断自动供应全部电力)。

③同一槽内两个键相器模块(如果键相器信号需要)。

④同一槽内两个TMR继电器模块(如果需要)

⑤相邻槽内的三个同类型监测器模块。

⑥相邻槽内2~3个通讯通路模块(如果与外设通讯时需要)。

The 3500 system now meets the reliability requirements, and the results of process failure analysis can be used to better determine the desired configuration of the 3500, with various options including:

1. Standard system

2. Standard system with redundant power supply

3. TMR3500 frame with single sensor input (TMRI/O: bus system) and single end-stage element.

4. TMR3500 frame with single sensor input (TMRI/O: bus system) and TMR final-stage element.

5. TMR3500 frame with triple sensor input (TMRI/O: discrete) and single end-stage element.

6. TMR3500 frame with triple sensor input (TMR1/O: discrete) and TMR final element.

In order to operate as a TMR system, the 3500 monitoring system must have the following modules installed:

① A frame interface module of TMR type

(2) Two power supplies (if one of them is found to be faulty, the other power supply can automatically supply all power without interruption).

③ Two key phase modules in the same slot (if the key phase signal is required).

④ Two TMR relay modules in the same slot (if required)

⑤ Three monitor modules of the same type in adjacent slots.

⑥ 2 to 3 communication path modules in adjacent slots (if necessary for communication with peripherals).
