HONEYWELL FC-PSU-240516 SM控制器的24Vdc电厂电源是不间断的

有0-20 mA、0-5 V和0-10 V现场信号的模拟输入。这些

可以将场信号转换为输入模块所需的输入电压

（例如0-2V或0-4V）。

输入模块在5 Vdc电路和现场输入之间具有电流隔离。

它们装配有符合DIN 41612的F型公连接器，

（b） 和z行。

以下项目终止于机箱连接器：

•5 Vdc内部电源

•24 Vdc或48 Vdc内部电源

•24 Vdc或48 Vdc外部电源（如果需要）

•输入信号接线

5 Vdc信号在物理上与IO连接和电源分离。

以下直流电源电压范围适用，以确保

安全管理器模块：

•110伏直流：+25%/–15%

•48伏直流：+15%/–15%

•24 Vdc：+30%/–15%

笔记：

1.如果不能保证提供给安全管理器的直流电仍然存在

在上述范围内，需要额外的电压监测。

2.假设提供给SM控制器的24Vdc电厂电源是不间断的。如果

否则，应提供避免24Vdc线路至

SM控制器。

3.使用厂用电时，厂用电必须满足规定的要求

在IEC 61010或IEC 60950中有所下降。

输入模块可以在电源打开的情况下更换。具体取决于输入

信号功能和系统IO配置，过程操作可以

影响

卸下输入模块时，首先断开扁平电缆与

水平IO总线（IOBUS-HBS或IOBUS-HBR），松开螺钉，然后

小心地将模块滑出机箱。

将输入模块放入机箱时，小心地将其推入插槽，直到

它与机箱齐平，拧紧螺钉，然后将扁平电缆连接到

水平IO总线（IOBUS-HBS或IOBUS-HBR）

There are analog inputs for 0—20 mA, 0—5 V and 0—10 V field signals. These

field signals can be converted to the required input voltage of the input modules

(such as 0—2 V or 0—4 V) by using an FTA or an input converter module.

Input modules have galvanic isolation between 5 Vdc circuitry and field inputs.

They are fitted with a male connector according to DIN 41612, type F, with the d,

(b) and z rows in use.

The following items terminate on the chassis connector:

• 5 Vdc internal power supply

• 24 Vdc or 48 Vdc internal power supply

• 24 Vdc or 48 Vdc external power supply (if needed)

• Wiring for the input signals

The 5 Vdc signals are physically separated from the IO connections and supply.

The following DC supply voltage ranges apply to ensure correct operation of the

Safety Manager modules:

• 110 Vdc: +25% / –15%

• 48 Vdc: +15% / –15%

• 24 Vdc: +30% / –15%

Notes:

1. If it cannot be guaranteed that the DC power supplied to Safety Manager remains

within the above ranges, additional voltage monitoring is required.

2. It is assumed that the 24Vdc Plant power fed to the SM Controller is uninterrupted. If

not, means should be provided to avoid power dips at the 24Vdc lines to the

SM Controller.

3. When using Plant power, the Plant power supply must fulfill the requirements as laid

down in IEC 61010 or IEC 60950.

Input modules can be replaced with power switched on. Depending on the input

signal function and the system IO configuration, process operation may be

affected.

When removing an input module, first disconnect the flat cable from the

horizontal IO bus (IOBUS-HBS or IOBUS-HBR), loosen the screws, and

carefully slide the module out of the chassis.

When placing an input module into the chassis, carefully push it into the slot until

it is flush with the chassis, fasten the screws, then connect the flatcable to the

horizontal IO bus (IOBUS-HBS or IOBUS-HBR)
