ABB 5SHY3545L0016 模塊實(shí)現(xiàn)冗余控制系統(tǒng)
施韋策工程實(shí)驗(yàn)室為其SEL-2240 Axion遠(yuǎn)程終端設(shè)備(RTU)或可編程邏輯控制(PLC)平臺(tái)增加了模塊和協(xié)議?？蛻衄F(xiàn)在可以訂購(gòu)低壓電源、四插槽背板、雙四插槽背板和IEC 61850 GOOSE。低壓電源支持24/48 Vdc電源。預(yù)先存在的高壓電源在同一單元中支持125/250 Vdc或120/240 Vac。它們可以單獨(dú)使用，也可以在同一個(gè)Axion單元中使用其中一個(gè)，從單獨(dú)的電源(如變電站交流電源和備用電池)中提供冗余電源。

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.
