NI SCXI-1121 SCXI電壓輸入模塊
負(fù)極輸入通道的信號端子位于B列中連接件的連接。每個(gè)相應(yīng)正輸入的信號端子通道位于接頭的C列中。每個(gè)輸入都會發(fā)送到一個(gè)多路復(fù)用至模塊輸出緩沖器的單獨(dú)濾波器和放大器。如果接線盒有溫度傳感器，則傳感器輸出-連接到針腳A3和A4（CJ傳感器）-也經(jīng)過過濾和多路傳輸?shù)侥K輸出緩沖區(qū)。
SCXI-SCXI-1121模塊輸入的差分輸入信號范圍當(dāng)使用1的增益時(shí)，信道為±10 V；當(dāng)使用1的增益時(shí)，信道為±0.1 V100.該差分輸入范圍是可測量電壓正負(fù)通道輸入之間的差異。這個(gè)SCXI-1121模塊輸入的共模輸入信號范圍通道為±10 V。該共模輸入范圍為正極或負(fù)極負(fù)通道輸入是導(dǎo)致有效輸出的輸入電壓
測量每個(gè)通道包括輸入保護(hù)電路，以承受意外施加高達(dá)±42 VAC峰值或60 VDC的電壓。
The signal terminal of the negative b channel is located in the connection of the connector in column B. The signal terminal channel for each corresponding positive b is located in column C of the connector. Each b is sent to a separate filter and amplifier multiplexed to the module output buffer. If the junction box has a temperature sensor, the sensor output - connected to pins A3 and A4 (CJ sensor) - is also filtered and multiplexed to the module output buffer.
The differential b signal range b by scxi-scxi-1121 module. When the gain of 1 is used, the channel is ± 10 V; When a gain of 1 is used, the channel is ± 0.1 V100 The differential b range is the difference between the positive and negative channel bs of the maximum measurable voltage. The common mode b signal range channel b by this scxi-1121 module is ± 10 v. The common mode b range is positive or negative, and the negative channel b is the maximum b voltage resulting in an effective outputEach measurement channel includes an b protection circuit to withstand an inadvertently applied voltage of up to ± 42 VAC peak or 60 VDC.
