ABB 216VC62A HESG324442R13控制主板卡件
1.产 品 详 情 资 料：
ABB 216VC62A HESG324442R13启动1。如果INIT保持时间小于2.5秒，则冷重启。2.如果INIT保持超过3秒，控制器复位。如果在冗余配置中的主CPU上按下INIT，则将启动到备用CPU的切换。外部电源连接+24 V DC电源0 V冗余电源监控输入冗余电源监控输出SH B+B–外部电池连接屏蔽（螺丝连接器）电池正极（螺丝连接器）电池负极（螺丝连接）Tx Rx模块总线连接数据传输端口（光学）数据接收端口（光学的）注意：可以使用双工或单工光缆。MODULEBUS（1）提供I/O单元能力的扩展。EX-BUS提供板载通信端口的扩展。适用于ABB 216VC62A HESG324442R13 RCU链路连接器在冗余配置的主CPU和备用CPU之间提供信息和数据传输。对ABB 216VC62A HESG324442R13 RCU数据链路连接器有效提供保持备份CPU与主CPU同步所需的数据传输。RCU控制链路连接器提供角色选择和CPU标识分配。ABB 216VC62A HESG324442R13
ABB 216VC62A HESG324442R13Initiates 1. Cold Restart if INIT is held less than 2.5 seconds. 2. Controller Reset if INIT is held more than 3 seconds. If INIT is pushed on the Primary CPU in redundant configuration a switchover to the backup CPU will be initiated.External Power Supply Connection +24 V DC supply 0 V Redundant Power Supply monitoring input Redundant Power Supply monitoring input SH B+ B– External Battery ConnectionABB 216VC62A HESG324442R13Shield (Screw Connector) Battery Positive (Screw Connector) Battery Negative (Screw Connector) Tx Rx ModuleBus Connection Data Transmission Port (Optical) Data Reception Port (Optical) Note – Duplex or Simplex optical cables may be used.
