美國NI C系列溫度采集輸入NI-9212是一款具有8個通道的模擬輸入模塊,用于采集溫度信號。它提供最大差分模擬輸入通道數(shù)量為8,采樣率為95 S/s/通道,每個通道間的隔離電壓高達60 Vrms。
NI-9212可以支持各種標準熱電偶和微型熱電偶(mini-TC)等傳感器類型。它還具有通道間隔離的功能,可以保護通道免受電壓沖擊和瞬態(tài)電壓的影響,適用于各種需要組隔離通道的應用場景,如大型家用電器測試、車載數(shù)據(jù)記錄、電池棧測試以及各種其他噪聲工業(yè)環(huán)境。
NI-9212的隔離電壓是通過在輸入通道之間放置隔離器件實現(xiàn)的。這些隔離器件可以是隔離放大器、光耦、電磁繼電器或其他隔離組件。通過這些隔離器件,NI-9212可以將輸入通道之間的電壓隔離,保護通道免受電壓沖擊和瞬態(tài)電壓的影響。
具體來說,NI-9212在內(nèi)部使用隔離放大器將輸入信號與模塊的其他部分分開。這種隔離技術可以有效地防止電氣噪聲和其他干擾信號對模擬輸入信號的影響,從而提高測量精度和可靠性。
除了使用隔離放大器,NI-9212還采用了其他隔離技術,如光耦和電磁繼電器等。這些隔離器件可以將輸入信號與模塊的其他部分完全分開,確保通道之間的隔離電壓高于最大允許電壓。


The NI-9212, a US NI C series temperature acquisition input module, is an analog input module with 8 channels used to collect temperature signals. It provides a maximum of 8 differential analog input channels, a sampling rate of 95 S/s/channel, and an isolation voltage of up to 60 Vrms between each channel.
NI-9212 can support various types of sensors such as standard thermocouples and micro thermocouples (mini TC). It also has the function of inter channel isolation, which can protect the channels from voltage shocks and transient voltages. It is suitable for various application scenarios that require group isolation channels, such as large-scale household appliance testing, on-board data recording, battery stack testing, and various other noisy industrial environments.
The isolation voltage of NI-9212 is achieved by placing isolation devices between input channels. These isolation devices can be isolation amplifiers, optocouplers, electromagnetic relays, or other isolation components. Through these isolation devices, NI-9212 can isolate the voltage between input channels, protecting them from voltage surges and transient voltages.
Specifically, the NI-9212 uses an isolation amplifier internally to separate the input signal from other parts of the module. This isolation technology can effectively prevent the influence of electrical noise and other interference signals on the analog input signal, thereby improving measurement accuracy and reliability.
In addition to using isolation amplifiers, NI-9212 also utilizes other isolation technologies such as optocouplers and electromagnetic relays. These isolation devices can completely separate the input signal from other parts of the module, ensuring that the isolation voltage between channels is higher than the maximum allowable voltage.
