NI SCXI-1121 SCXI電壓輸入模塊
負極輸入通道的信號端子位于B列中連接件的連接。每個相應正輸入的信號端子通道位于接頭的C列中。每個輸入都會發(fā)送到一個多路復用至模塊輸出緩沖器的單獨濾波器和放大器。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使用1的增益時，信道為±10 V；當使用1的增益時，信道為±0.1 V100.該差分輸入范圍是可測量電壓正負通道輸入之間的差異。這個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極負通道輸入是導致有效輸出的輸入電壓
測量每個通道包括輸入保護電路，以承受意外施加高達±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.
