描述
BC810K02 ABB 電源連接器
BC810由兩個基本部件組成:底板(TP857)和電源/邏輯板。底板是cex總線和外部電源的連接器所在的位置。它通過外殼的金屬部件接地到din導軌上。該板還攜帶外部電源投票二極管和保險絲。電源和邏輯板包含+3.3 V轉換器、邏輯、CEX-Bus互連驅動器和互連電纜連接器。BC810可與PM857、PM861A、PM862、PM863、PM864A、PM865、PM866、PM866A、PM867、PM891配套使用。在全冗余系統中,BC810支持CPU基板的在線更換,且不影響CEX業務流量。更換BC810時,連接CEX段的流量將全部停止。cex總線用于通過通信接口單元擴展板載通信端口。還可以在cex總線上使用冗余通信接口。CEX-Bus互連單元BC810用于通過將CEX-Bus劃分為單獨的段來增加其可用性。這提高了具有冗余通信接口的系統的可用性
The BC810 unit consists of two basic parts:baseplate(TP857)and power supply/logic board.The baseplate is where the connectors to CEX-Bus and the external power reside.It is grounded to the DIN-rail through metal parts of the housing.The board also carries the external power voting diode and fuse.The power supply and logic board contain the+3.3 V converter,logic,drivers for CEX-Bus interconnection,and the connector for the interconnection cable.
The BC810 can be used with PM857,PM861A,PM862,PM863,PM864A,PM865,PM866,PM866A,PM867 and PM891.
In a fully redundant system with two interlinked BC810 and primary/backup CPU pair,the BC810 support online replacement of the CPU baseplate without disturbing the CEX traffic.If the BC810 has to be replaced,all traffic to the connected CEX segment is stopped.
The CEX-Bus is used for extending the onboard communication ports with communication interface units.It is also possible to use redundant communication interfaces on the CEX-Bus.The CEX-Bus Interconnection unit BC810 is used to increase the availability of the CEX-Bus by dividing it into separate segments.This improves the availability of systems with redundant communication interfaces.
