VMIVME-3113A 模数转换器

VMIVME-3113A是一款模数转换器模块，其设计能够支持多达64个通道的差分和/或单端宽范围模拟输入（正负10 mV至正负10 V）。该模块具有多种功能和特点，使其在工业自动化和控制系统等领域具有广泛的应用。

首先，VMIVME-3113A模块集成了一个64字双端口，为连续扫描设备的所有通道提供存储。不同的扫描模式在通电、系统重置或在程序控制下手动输入时自动启用。双端口寄存器允许操作员随时访问VMEbus以读取最新存储的数据。这种设计使得数据的读取和存储变得非常便捷和高效。

其次，VMIVME-3113A模块的跳线可选可编程增益放大器能够支持1、10、100、200和高达500的增益范围。这意味着用户可以根据需要调整增益，以适应不同的输入信号范围。此外，该模块的模数转换时间为15µs，保证了快速且准确的数据转换。

在数据读取方面，VMIVME-3113A模拟输入被数字化并存储在64个双端口寄存器中，作为一个12位数字值（D11到Do0），用户可以读取。可选择的数据代码是二进制、偏移二进制和二的补码。符号扩展到上面的4位（D12，D13，D14和D15）。这种设计使得数据的读取和处理变得灵活和方便。

此外，VMIVME-3113A模块还具有多种操作模式和测试模式，以满足不同的应用需求。例如，系统复位自动将单板置于自动扫描模式；随机轮询模式要求控制程序生成一个单一的转换；随机中断模式与随机PollMode相同，只是转换结束时产生对cpu的中断。这些模式使得用户可以根据具体的应用场景选择合适的操作方式。

总的来说，VMIVME-3113A是一款功能强大、性能稳定的模数转换器模块。它支持多种扫描模式和增益范围，具有快速的数据转换能力和灵活的数据读取方式。这使得它在工业自动化、控制系统以及其他需要精确模拟信号转换的领域具有广泛的应用前景。

VMIVME-3113A 模数转换器

The VMIVME-3113A is an analog-to-digital converter module designed to support up to 64 channels of differential and/or single-ended wide-range analog inputs (plus or minus 10 mV to plus or minus 10 V). The module has a variety of functions and features, making it widely used in industrial automation and control systems.

First, the VMIVME-3113A module integrates a 64-word dual port to provide storage for all channels of the continuous scanning device. Different scanning modes are automatically enabled when powered on, system reset, or manually entered under program control. The dual-port register allows the operator to access the VMEbus at any time to read the latest stored data. This design makes the reading and storage of data very convenient and efficient.

Second, the jumper optional programmable gain amplifier of the VMIVME-3113A module is capable of supporting gain ranges of 1, 10, 100, 200 and up to 500. This means that users can adjust the gain as needed to accommodate different ranges of input signals. In addition, the module’s analog-to-digital conversion time is 15µs, which guarantees fast and accurate data conversion.

In terms of data reading, the VMIVME-3113A analog input is digitized and stored in 64 dual-port registers as a 12-bit digital value (D11 to Do0) that can be read by the user. Alternative data codes are binary, offset binary, and two’s complement. The symbol extends to the above 4 bits (D12, D13, D14, and D15). This design makes the reading and processing of data flexible and convenient.

In addition, the VMIVME-3113A module also has a variety of operating modes and test modes to meet different application requirements. For example, a system reset automatically puts the board in automatic scan mode. Random polling mode requires the controller to generate a single transformation; The random interrupt mode is the same as the random PollMode, except that an interrupt to the cpu is generated at the end of the conversion. These modes enable users to choose the appropriate operation mode according to the specific application scenario.

Overall, the VMIVME-3113A is a powerful and stable ADC module. It supports a variety of scan modes and gain ranges, with fast data conversion capabilities and flexible data reading methods. This makes it promising for a wide range of applications in industrial automation, control systems, and other fields that require accurate analog signal conversion.
