IS200VAICH1DAB模型用于TMR或单工应用中的Mark V系统

由通用电气制造的模拟输入/输出板，IS200VAICH1DAB模型用于TMR或单工应用中的Mark V系统。当用于TMR系统配置时，附加的终端板(TBAIH1C或STAI板)上的输入信号将被扇形分布到三个VME机架，T, R和S，每个机架包含一个VAIC板。

VAIC板上的输出信号将由专有电路驱动，使用所有可用的VAIC板产生理想的电流。如果VME机架上的任何IS200VAICH1DAB型号出现故障，则会将故障的VAIC型号从输出中移除，剩余的VAIC板可以继续提供正确的电流。当该模型用于单工配置时，附加的端子板将为其中一个VAIC模型提供输入，为输出提供所有电流。

在IS200VAICH1DAB模型运行期间，它将控制4个模拟输出并接受多达20个模拟输入。该模型具有模拟MUX, A/D转换器，D/A转换器和信号调理。该型号有两个模拟输入，±1ma或4- 20ma，由附加端子板上的跳线选择。模拟输出电路分为两部分;两个输出可配置为0-200 mA或4-20 mA，其他输出仅为4-20 mA。IS200VAICH1DAB型号的输入和输出都包含高抑制电路，以防止高频噪声和浪涌。

An analog input/output board manufactured by GE, the IS200VAICH1DAB model is used for Mark V systems in TMR or simplex applications. When used in a TMR system configuration, the input signals on the additional terminal boards (TBAIH1C or STAI boards) are fanned out across three VME racks, T, R, and S, each containing a VAIC board.

The output signal on the VAIC board will be driven by a proprietary circuit, using all available VAIC boards to generate the ideal current. If any IS200VAICH1DAB model on the VME rack fails, the faulty VAIC model is removed from the output and the remaining VAIC board can continue to provide the correct current. When the model is used in a simplex configuration, the additional terminal board will provide the input to one of the VAIC models and all the current to the output.

During the operation of the IS200VAICH1DAB model, it will control 4 analog outputs and accept up to 20 analog inputs. The model has analog MUX, A/D converter, D/A converter and signal conditioning. This model has two analog inputs, ±1ma or 4-20ma, selected by a jumper on the attached terminal board. The analog output circuit is divided into two parts; Two outputs can be configured to be 0-200 mA or 4-20 mA, and the other outputs are only 4-20 mA. Both the input and output of the IS200VAICH1DAB model contain high suppression circuits to prevent high-frequency noise and surges.
