通过电源断路器、电源装置和SS83X表决装置，连接至
24V直流配电端子。
AC 800M控制器及其I/O系统通常位于一个或多个
外壳或机柜。容纳AC 800M控制器的机柜还可以：
包含通过电气模块总线连接到控制器的I/O单元
光纤模块总线或PROFIBUS DP的通信接口。
包含AC 800M控制器的机柜
可能需要从该机柜获得以下电源：
•供电单元：为机柜中每个单元的电子电路供电。
•现场设备供电：设备电源、继电器触点等
机柜外部，但连接到机柜中I/O单元的输入/输出

包含I/O系统的机柜
如果I/O中未提供其他信息，请使用上述建议
系统文档。
强烈建议：
•使用每个机柜中的电源为装置供电（仅当机柜
并且大电缆长度小于10m，
装置的电源是否可以从另一个机柜获取
•使用单独的电源为单元供电（包括S800集群
调制解调器）和为现场设备供电

机柜中的供电单元
该电源仅连接到机柜内的单元，例如：
•PM8XX，还为所有通信接口供电（通过CEX总线）
所有S800 I/O单元连接到其电气模块总线。
•BC810为连接到其自身网段的所有通信接口供电。
•TB820V2/TB840（用于S800 I/O的光调制解调器），也为所有S800供电
连接到其电气模块总线的I/O单元。
•CI840和CI801（用于S800 I/O的PROFIBUS DP接口），还提供电源
所有S800输入/输出单元均连接至其电气模块总线。
•用于其他I/O系统的PROFIBUS DP适配器（取决于供应
I/O单元的布置，可能需要将电源连接到每个I/O
单位）。
•机柜内的通信调制解调器。
此电源的主要配置规则是将24 V电缆保持在

干扰
从AC 800M控制器中的电源为现场设备供电
机柜通常需要使用长的24 V直流电缆，这些电缆可以很容易地连接到本地
干扰并将其直接返回到电源单元。安装时
电缆，请遵循第62页电缆下的现场电缆说明。
电源输出短路
SD83X系列电源在其输出端没有额外的储能器。在
如果发生短路，电源输出电压将迅速下降。
短路（即使在24V直流配电系统中安装了保险丝）或较大
负载变化可能会在电源中产生不希望的电压下降Optical

Section 3 Configuration Power Supply System

Power Supply System
The configuration of a power supply system for an AC 800M controller is very
straightforward.
Configurations
Figure 61 on page 177 and Figure 62 on page 178 gives a series of simple circuit
diagrams showing various possibilities for connecting the incoming mains power –
via the mains breaker, the power supply units and the SS83X voting devices – to the
24 V DC distribution terminals.
The AC 800M Controller and its I/O system are normally located in one or several
enclosures or cabinets. The cabinet housing the AC 800M Controller can also
contain I/O units connected to the controller via the electrical ModuleBus, the
optical ModuleBus or the communication interfaces for PROFIBUS DP.
Cabinet Containing AC 800M Controller
From this cabinet power may be required for:
• Powering Units: power to the electronic circuitry for each unit in the cabinet.
• Powering Field Equipment: power to equipment, relay contacts etc. located
outside the cabinet, but connected to the inputs/outputs of the I/O units in the
cabinet.
Cabinet Containing I/O System
Use the recommendations given above if no other information is given in the I/O
system documentation.
It is strongly recommended to:
• use a power supply in each cabinet for Powering Units (only when cabinets
are mounted side by side, and the maximum cable length is less than 10 m,
can power to the units be taken from another cabinet)
• use separate power supplies for Powering Units (including S800 cluster
modems) and Powering Field Equipment
Powering Units in the Cabinet Section 3 Configuration
174 3BSE036351-510 A
Powering Units in the Cabinet
This power supply is only connected to units within the cabinet such as:
• PM8XX, which also powers all communication interfaces (via the CEX-Bus)
and all S800 I/O units connected to its electrical ModuleBus.
• BC810 powers all communication interfaces connected to its own segment.
• TB820V2/TB840 (optical modem for S800 I/O) which also powers all S800
I/O units connected to its electrical ModuleBus.
• CI840 and CI801 (PROFIBUS DP interface for S800 I/O) which also powers
all S800 I/O units connected to its electrical ModuleBus.
• PROFIBUS DP adapters for other I/O systems (depending on the supply
arrangement for the I/O units, it may be necessary to connect power to each I/O
unit).
• Communication modems located in the cabinet.
The main configuration rule for this power supply is to retain the 24 V cables within
the cabinet.
Powering Field Equipment outside the Cabinet
This is intended for supplying power to process signals and equipment located
outside the cabinet.
Interference
Powering field equipment from a power supply located in the AC 800M Controller
cabinet often requires the use of long 24 V DC cables that can easily pick up local
interference and direct it straight back to the power supply units. When installing the
cables, follow the instructions for Field Cables, given under Cables on page 62.
Short-Circuit at Power Supply Output
The SD83X series power supply has no extra energy reservoir at its outputs. In the
event of a short circuit the power supply output voltage will fall rapidly.
Short circuits (even with fuses installed in the 24 V DC distribution system) or large
load changes can produce unwanted voltage dips in supply
