VMIVME-3122  GE 高分辨率、16位、64通道模拟扫描和数字化输入板

Abaco Systems/VMIC VMI VME-3122/VMI VME-3122 a是一款高分辨率、16位、64通道模拟扫描和数字化输入板，适合VMEbus系统应用。双端口数据存储器、板载定时器、自动控制增益和可编程总线中断器使VMIVME-3122能够支持大量模拟输入流量，而主机处理器的参与最少。

VMIVME-3122是VMIC广泛的VMEbus模拟输入/输出产品系列中的一员。VMIVME-3122具有16位数字化分辨率、程控增益、可选转换速率和64路差分或单端模拟输入自动扫描功能，可提供出色的动态范围和模拟输入通道密度。支持各种工作模式，包括自动扫描、数据突发和外部同步。该板旨在与VMIC的信号调理板系列直接接口，用于将热电偶、RTD和应变计的输出数字化。

可以下载单个通道的增益，供扫描操作时使用，也可以将电路板配置为所有通道通用的固定增益。多个电路板可以同步在一起，使多达16个电路板同时启动每次扫描。间隔定时器、总线中断器、通道计数器和Midscan/Endscan标志简化了双端口数据缓冲器内的数据监控。受益于VMIVME-3122功能的系统应用包括工厂自动化、过程控制、数据采集系统、培训模拟器和实验室仪器。

The Abaco Systems / VMIC VMIVME-3122 / VMIVME-3122A is a high-resolution, 16-bit, 64-channel analog scanning and digitizing input board for VMEbus system applications. Dual-ported data memory, on-board timers, automatically controlled gain and a programmable bus interrupter enable the VMIVME-3122 to support extensive analog input traffic, with minimum involvement of the host processor.

The VMIVME-3122 is a member of VMIC’s extensive family of analog input/output products for the VMEbus. With 16-bit digitizing resolution, program-controlled gain, selectable conversion rate, and automatic scanning of 64 differential or single-ended analog inputs, the VMIVME-3122 provides exceptional dynamic range and analog input channel density. Various operating modes are supported, including auto-scanning, data bursts and external synchronization. This board is designed to interface directly with VMIC’s line of signal conditioning boards for digitizing the outputs from thermocouples, RTDs and strain gages.

Individual channel gains can be downloaded for use during scanning operations, or the board can be configured with a fixed gain that is common to all channels. Multiple boards can be synchronized together to enable as many as 16 boards to initiate each scan simultaneously. An Interval Timer, Bus Interrupter, Channel Counter and Midscan/Endscan flag simplify the monitoring of data within the dual port data buffer. The system applications that can benefit from the VMIVME-3122 capabilities include factory automation, process control, data acquisition systems, training simulators and laboratory instrumentation.
