IC200ALG331-KD VersaMax I/O平台的模拟输出模块

IC200ALG331是VersaMax I/O平台的模拟输出模块，由紧凑型、多功能和可扩展的分布式I/O模块组成。该零件号代表一个16位、电压和电流可配置模块，带有四(4)个独立隔离的输出通道。

该模块用于启动和调节最终控制元件(FCE ),例如用于流量控制的控制阀、用于电机速度和扭矩控制的变频驱动器(VFD)、设施和HVAC应用中的风门和百叶窗以及其他配有定位器的设备。该模块也可用于中继模拟信号，该信号可能是可编程逻辑控制器(PLC)逻辑内连续计算的结果，由面板仪表显示并由数据记录器记录。它还可以用来与信号隔离器或信号分离器接口，或将参考信号级联到另一个单环路控制器或PLC，以实现更复杂的控制器架构，如级联控制。

IC200ALG331具有输出通道，可通过软件配置产生+/- 10 VDC或4-20 mA输出信号。每个通道的最大更新速率为7 ms，精度为最大满量程的+/- 0.1%。每个通道还能够配置和检测上限/下限、超量程/欠量程、开路、现场电源损耗、非易失性存储器故障，以及单独分配输出行为以响应PLC停止或模块错误，例如保持最后状态或下调至零(0)，这也可以修改。由于IC200ALG331完全可通过软件配置，因此无需在该模块上安装终端跳线来设置工作模式。

IC200ALG331-KD VersaMax I/O平台的模拟输出模块

The IC200ALG331 is the analog output module for the VersaMax I/O platform, consisting of compact, versatile and scalable distributed I/O modules. The part number represents a 16-bit, voltage and current configurable module with four (4) independently isolated output channels.

The module is used to start and regulate final control elements (FCE), such as control valves for flow control, variable frequency drives (VFDS) for motor speed and torque control, damper and shutters in facilities and HVAC applications, and other devices with positioners. The module can also be used to relay an analog signal that may be the result of a continuous calculation within the logic of a programmable logic controller (PLC), displayed by a panel meter and recorded by a data logger. It can also be used to interface with a signal isolator or signal separator, or to cascade a reference signal to another single-loop controller or PLC for more complex controller architectures such as cascade control.

The IC200ALG331 has an output channel that can be configured by software to produce a +/ -10 VDC or 4-20 mA output signal. The maximum update rate per channel is 7 ms with an accuracy of +/ -0.1% of the maximum full scale. Each channel is also capable of configuring and detecting upper/lower limits, over/under ranges, open circuit, field power losses, non-volatile memory failures, and individually assigning output behavior in response to PLC stops or module errors, such as holding the last state or downtuning to zero (0), which can also be modified. Since IC200ALG331 is fully software configurable, there is no need to install terminal jumpers on the module to set the operating mode.
