ABB 5SHY3545L0016 模块实现冗余控制系统
施韦策工程实验室为其SEL-2240 Axion远程终端设备(RTU)或可编程逻辑控制(PLC)平台增加了模块和协议。客户现在可以订购低压电源、四插槽背板、双四插槽背板和IEC 61850 GOOSE。低压电源支持24/48 Vdc电源。预先存在的高压电源在同一单元中支持125/250 Vdc或120/240 Vac。它们可以单独使用，也可以在同一个Axion单元中使用其中一个，从单独的电源(如变电站交流电源和备用电池)中提供冗余电源。

ABB 5SHY3545L0016 module implements redundant control system
Schweitzer Engineering Laboratory has added modules and protocols to its SEL-2240 Axion Remote Terminal Unit (RTU) or Programmable Logic Control (PLC) platform. Customers can now order low-voltage power supplies, four slot backplanes, dual four slot backplanes, and IEC 61850 GOOSE. The low-voltage power supply supports 24/48 Vdc power supply. The pre-existing high-voltage power supply supports 125/250 Vdc or 120/240 Vac within the same unit. They can be used alone, or one of them can be used within the same Axion unit, providing redundant power from separate power sources such as substation AC power and backup batteries.
