部件号: 332-113126-100, 350-113126-100, 332-103126-100
特征:
8 或 16 个模拟输入通道
每通道RTD激励源(200 μA或400 μA)
每通道开放换能器检测器
单极性/双极性满量程ADC范围为5 mV至10 V
VMIC VMIVME-3126A 高分辨率隔离式模数转换器板具有 16 个独立的隔离输入通道,分辨率为 16 位。每个输入都有一个专用的模数转换器 (ADC)、输入调理、基准电压源和电源。每个通道都通过光隔离器与VMEbus和数字电路隔离。自检由 VMEbus 系统复位或执行软件命令启动。数字信号处理器 (DSP) 提供控制和软件校正数据。电可擦除可编程只读存储器 (E2PROM) 在复位条件下将失调和增益系数加载到 DSP 中。用户可以通过进入校准模式重新计算失调和增益系数。DSP还可以根据用户定义的截止频率进行软件滤波。

The VMIC VMIVME-3126A high resolution isolated analog-to-digital converter board has 16 separate isolated input channels with a resolution of 16 bits. Each input has a dedicated analog-to-digital converter (ADC), input conditioning, voltage reference source, and power supply. Each channel is isolated from the VMEbus and digital circuits by optical isolators. The self-test is initiated by resetting the VMEbus system or by executing a software command. A digital signal processor (DSP) provides control and software correction data. Electrically erasable programmable read-only memory (E2PROM) loads the offset and gain factors into the DSP under reset conditions. The user can recalculate the offset and gain coefficients by entering calibration mode. The DSP can also perform software filtering based on user-defined cutoff frequencies.
