先進(jìn)保護(hù)
SEL-710提供過電流、熱過負(fù)荷、低電流、電流不平衡、電流差動(dòng)、缺相、接地故障以及過頻低頻以及其他更多的保護(hù)功能。
易于通信
選擇單股或雙股銅線或光纖以太網(wǎng)端口、以及Modbus TCP、IEC 61850、串行Modbus、EIA-232、EIA-485、Telnet和文件傳輸協(xié)議(FTP)通信選擇一個(gè)或多個(gè)連接,包括多個(gè)Modbus會(huì)話來自定義您應(yīng)用的配置。
堅(jiān)固的設(shè)計(jì)
SEL-710提供了業(yè)界廣泛的環(huán)境溫度工作范圍,-40°至+85°C(-40°C至+185°F)。
SEL-710電機(jī)保護(hù)繼電器選型
靈活的I/ O,可用于本地控制和系統(tǒng)應(yīng)用:基本單元包括三個(gè)數(shù)字輸出和兩個(gè)數(shù)字輸入。有三種卡插槽用于可選SELectI/ O卡,其中包括以下:
四 個(gè)數(shù)字輸入 (DI) 和 四 個(gè)數(shù)字輸出 (DO)
四個(gè)快速混合DO,和四個(gè)DI
八個(gè) DI
四個(gè)DO, 三個(gè)DI, 和一個(gè)模擬輸出 (AO)
四個(gè)模擬輸入 (AI) 和四個(gè)AO
八個(gè) AI 直流過程值
三個(gè)交流電壓輸入
電流差動(dòng)和三個(gè)交流電壓輸入
十個(gè) RTD 輸入。
選擇IRIG-B時(shí)間碼輸入或PTC(熱敏電阻)的輸入
外部RTDs(安裝在靠近電機(jī)的SEL-2600A或SEL-2600D RTD模塊上,有12個(gè) RTD輸入和一個(gè)觸點(diǎn)輸入)
從以太網(wǎng)、Modbus TCP、IEC61850、串行Modbus、EIA-232、EIA-485、Telnet和文件傳輸協(xié)議(FTP)的各種通信中選擇。
保形涂層:保護(hù)設(shè)備免接觸硫化氫、氯、鹽和濕氣等惡劣環(huán)境和氣載污染物。
改造更換套件: 用SEL-710直接更換套件替換現(xiàn)有的電機(jī)控制。這些套件提供使用 SEL-710替換許多舊電機(jī)保護(hù)繼電器所需的一切:
