SMC氣動用壓力開關(guān)的種類,IS3000-02L5產(chǎn)品特點

當使用觸點“A"或只“A＆B"接觸
由于發(fā)光二極管（LED）的光用于
燈組件24伏直流電，有2個
終端和極性。一個是“+"，用于紅色負載

線，而另一個是“ - "為黑負載線。
如果接線錯誤燈不亮。
光光纖組件24 VDC有3 mA電流
泄漏。直接連接導致
如果PLC的輸入端的電源
切換為關(guān)閉在任何時候，由于泄漏。

絕緣電阻：100MΩ或以上500 VDC通過兆歐表
耐電壓：1500 VAC，5 0/60赫茲1分鐘。 （當使用開關(guān)霓虹燈：1000 VAC1分鐘）
Insulation resistance: 100 MΩ or more at 500 VDC by megameter
Voltage resistance: 1500 VAC, 5 0 / 6 0 Hz for 1 min. (When using switch with neon light: 1000 VAC for 1 min.)

When using contact “a" only or “a&b" contacts
Since the light emitting diode (LED) is used for
the light assembly for 24 VDC, there are 2
terminals and polarity. One is “+" for red load
wire and the other is “–" for black load wire.
Light will not light up if wired incorrectly.
Light ass'y for 24 VDC has 3 mA of current
leakage. Connect the LED directly to the
power supply if the input of the PLC sees the
switch as closed at all times due to leakage.
