说明：  ?USB ADIO 八件套：LabVIEW虚拟仪器开发板 电脑USB供电，无需外部电源，2路AI，2路DI，2路DO（可驱动3.3V继电器），2路5V电源输出。可直接配合上百种传感器使用，9种自动保护措施，安全方便。无需驱动，采样率可达每通道20kHz，可在Windows XP、WIN7（32/64位）、WIN8（32/64位）、WIN10等操作系统下稳定运行，有配套的电脑软件，包含波形显示、存储、分析等十余种功能，操作简单直观。 端子定义说明 ? AI0、AI1为模拟量信号输入端子； ? DI0、DI1为数字量信号输入端子； ? DO0、DO1为数字量信号输出端子； ? 5Vo是5V电源输出端子； ? GND为公共接地端。(Eight sets of USB ADIO: LabVIEW Virtual Instrument Development Board Computer USB power supply, without external power supply, 2 AI, 2 DI, 2 DO (3.3V relay drive), 2 5V power output. It can be directly used with hundreds of sensors, 9 automatic protection measures, safe and convenient. Without driver, the sampling rate can reach 20 kHz per channel. It can run steadily under Windows XP, WIN7 (32/64 bits), WIN8 (32/64 bits), WIN10 and other operating systems. It has supporting computer software, including more than ten functions such as waveform display, storage, analysis and so on. The operation is simple and intuitive. Terminals Definition Description AI0 and AI1 are analog signal input terminals. DI0 and DI1 are digital signal input terminals. DO0 and DO1 are digital signal output terminals. 5Vo is the output terminal of 5V power supply. GND is a common ground terminal.)
