ABB YB560103-CD DSQC236G电源驱动板
1.产 品 详 情 资 料:
ABB YB560103-CD DSQC236G强烈建议:•在每个机柜中为供电单元使用一个电源(只有当机柜并排安装,且最大电缆长度小于10米时,才能从另一个机柜中为单元供电)•为供电单元(包括S800集群调制解调器)和包含I/O系统的现场设备机柜使用单独的电源如果I/O系统文档中未提供其他信息,则上文给出的建议。机柜中的单元供电该电源仅连接到机柜内的单元,例如:•ABB YB560103-CD DSQC236G,它还为所有通信接口(通过CEX总线)和连接到其电气模块总线的所有S800 I/O单元供电。•BC810为连接到其自身网段的所有通信接口供电。•ABB YB560103-CD DSQC236G,也为连接至其电气模块总线的所有S800 I/O单元供电。•CI840和CI801(用于S800 I/O的PROFIBUS DP接口),也为连接至其电气模块总线的所有S800 I/O单元供电。•其他I/O系统的PROFIBUS DP适配器(取决于I/O单元的电源安排,可能需要将电源连接到每个I/O单元)机柜中的通信调制解调器。此电源的主要配置规则是将24 V电缆保留在机柜内。ABB YB560103-CD DSQC236G
ABB YB560103-CD DSQC236GIt 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 Cabinet Containing I/O System Use the recommendations given above if no other information is given in the I/O system documentation.Powering Units in the Cabinet This power supply is only connected to units within the cabinet such as: • ABB YB560103-CD DSQC236G, 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. • ABB YB560103-CD DSQC236G 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.ABB YB560103-CD DSQC236G
