這SCXI-1124(零件號(hào):776572-24) 6通道是否隔離模擬輸出模塊用于靜態(tài)DC(低帶寬)電壓或電流信號(hào)。一個(gè)通道的最大更新速率為555 S/s，所有六個(gè)通道的最大更新速率均為125 S/s。這鎳SCXI-1124集成6個(gè)自主隔離的12位數(shù)模轉(zhuǎn)換器(DAC)通道。用戶可以設(shè)置每個(gè)通道的電壓或電流輸出。對(duì)于電壓，用戶可以選擇三個(gè)單極性或三個(gè)雙極性范圍。對(duì)于電流，每個(gè)通道輸出0至20 mA。

這模擬輸出模塊是軟件可配置的，集成了本地可用的EEPROM，用于保存校準(zhǔn)常數(shù)。該模塊非常適合需要有限電壓或電流輸出來(lái)控制程序的應(yīng)用。對(duì)于更多的頻道，用戶可以利用幾個(gè)倪SCXI 1124SCXI框架中的模塊，以及其他信號(hào)調(diào)理I/O模塊。

利用該模塊，用戶可以針對(duì)以下電壓輸出范圍對(duì)每個(gè)通道進(jìn)行軟件編程:0至1、0至5、0至10、1、5或10 V。在單個(gè)模塊內(nèi)，用戶可以逐步關(guān)聯(lián)通道，使每個(gè)模塊的輸出信號(hào)最高可達(dá)60 VDC。每個(gè)電壓通道都集成一個(gè)低阻抗輸出緩沖器，最高可驅(qū)動(dòng)5 mA電流。

這SCXI 1124是通過(guò)SCXIbus數(shù)字傳輸?shù)?，所以一個(gè)DAQ小工具就能控制幾個(gè)鎳SCXI-1124模塊。在多路復(fù)用串行模式下，一個(gè)DAQ小工具控制至少一個(gè)SCXI-1124模塊通過(guò)SCXIbus利用串行計(jì)算機(jī)化信息慣例。這種活動(dòng)方法最多使用模塊DAQ小工具的五條計(jì)算機(jī)化I/O線。

The SCXI-1124 (Part Number: 776572-24) is a 6-channel isolated Analog Output Module for static DC (low bandwidth) voltage or current signals. The maximum update rate is 555 S/s for one channel and 125 S/s per channel for all six channels. The NI SCXI-1124 incorporates six autonomously isolated, 12-bit digital-to-analog converter (DAC) channels. The user can arrange each channel for voltage or current output. For voltage, the user has the option to pick any of the accessible three unipolar or three bipolar ranges. For current, each channel outputs between 0 to 20 mA.

This Analog Output Module is software configurable and incorporates a locally available EEPROM for saving calibration constants. This module is perfect for applications requiring confined voltage or current outputs to control a procedure. For more channels, the user can utilize a few NI SCXI 1124 modules in a SCXI framework, alongside other signal conditioning I/O modules.

With this module, the user can software program each channel for the following voltage output ranges: 0 to 1, 0 to 5, 0 to 10, ±1, ±5, or ±10 V. Within a single module, the user can progressively associate channels to make output signals up to 60 VDC per module. Every voltage channel incorporates a low impedance output buffer that can drive up to 5 mA.

The SCXI 1124 is digitally over the SCXIbus, so a single DAQ gadget can control a few NI SCXI-1124 modules. In multiplexed serial mode, one DAQ gadget controls at least one SCXI-1124 module through the SCXIbus by utilizing a serial computerized information convention. This method of activity utilizes a maximum of five computerized I/O lines of the module DAQ gadget.
