有0-20 mA、0-5 V和0-10 V現(xiàn)場信號的模擬輸入。這些

可以將場信號轉換為輸入模塊所需的輸入電壓

（例如0-2V或0-4V）。

輸入模塊在5 Vdc電路和現(xiàn)場輸入之間具有電流隔離。

它們裝配有符合DIN 41612的F型公連接器，

（b） 和z行。

以下項目終止于機箱連接器：

?5 Vdc內部電源

?24 Vdc或48 Vdc內部電源

?24 Vdc或48 Vdc外部電源（如果需要）

?輸入信號接線

5 Vdc信號在物理上與IO連接和電源分離。

以下直流電源電壓范圍適用，以確保

安全管理器模塊：

?110伏直流：+25%/–15%

?48伏直流：+15%/–15%

?24 Vdc：+30%/–15%

筆記：

1.如果不能保證提供給安全管理器的直流電仍然存在

在上述范圍內，需要額外的電壓監(jiān)測。

2.假設提供給SM控制器的24Vdc電廠電源是不間斷的。如果

否則，應提供避免24Vdc線路至

SM控制器。

3.使用廠用電時，廠用電必須滿足規(guī)定的要求

在IEC 61010或IEC 60950中有所下降。

輸入模塊可以在電源打開的情況下更換。具體取決于輸入

信號功能和系統(tǒng)IO配置，過程操作可以

影響

卸下輸入模塊時，首先斷開扁平電纜與

水平IO總線（IOBUS-HBS或IOBUS-HBR），松開螺釘，然后

小心地將模塊滑出機箱。

將輸入模塊放入機箱時，小心地將其推入插槽，直到

它與機箱齊平，擰緊螺釘，然后將扁平電纜連接到

水平IO總線（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)
