VM600-ABE040 Vibro-Meter 系统机架 PLC控制网络系统

USB-8451 是一款由美国国家仪器（National Instruments）生产的I2C/SPI接口设备数据采集卡。它使用I2C、SMBus和SPI协议连接到设备并进行通信。作为集成电路（I2C）或SCSI并行接口（SPI）设备的主节点或从节点接口，USB-8451用于连接集成电路（I2C）、系统管理总线以及串行外设接口设备，并与其进行通信。它具有即插即用的USB连接，是一款便携式解决方案，适用于与消费电子产品或集成电路的通信。

此外，USB-8451还包括八条通用数字I/O线，可用于各种应用，例如配置I2C设备的地址或切换LED。与PCI接口相比，该模块可以安装在更靠近I2C/SPI设备的位置，从而减少I2C总线长度并有效减少噪声问题。此外，该接口无需外部电源，即可为电源电路提供+5V和GND电压。

The USB-8451 is an I2C/SPI interface device data acquisition card manufactured by National Instruments. It uses I2C, SMBus, and SPI protocols to connect to and communicate with devices. As a master or slave node interface for integrated circuit (I2C) or SCSI parallel interface (SPI) devices, the USB-8451 is used to connect and communicate with integrated circuit (I2C), system management bus, and serial peripheral interface devices. It has a plug-and-play USB connection and is a portable solution for communication with consumer electronics or integrated circuits.

In addition, the USB-8451 includes eight universal digital I/O cables that can be used for a variety of applications, such as configuring the address of an I2C device or switching leds. The module can be installed closer to the I2C/SPI device than the PCI interface, reducing the I2C bus length and effectively reducing noise issues. In addition, the interface provides +5V and GND voltage to the power supply circuit without the need for an external power supply.
