IC693ALG221 具有模拟输入功能的组件模块

【产品详情】

IC693ALG221是一个模拟输入模块，是系列90-30可编程逻辑控制(PLC)系统的一部分。该模块是一个具有模拟输入功能的组件模块。该模块具有四(4)个输入通道，接收来自现场设备和仪器的0-20 mA和4-20 mA输入信号。该模块配备了一个内部模数转换器(ADC)，使PLC能够处理和进一步调节用户程序中使用的信号。

IC693ALG221的输入分辨率为12位，每个输入范围的分辨率为4µa (1 LSB = 4µa)，用于4-20 mA输入信号，5µa (1 LSB = 5µa)用于0-20 mA输入信号。它的绝对精度为0.1%满量程+ 0.1%读数，共模电压为200V。此外，该模块的线性度< 1最低有效位，输入滤波器响应为325 Hz。

IC693ALG221默认通道设置为4 ~ 20ma。当接收到4- 20ma信号时，模块内部将信号范围转换为0-32000，这是一个代表输入寄存器值的无单位测量值。0对应4ma, 32000对应20ma。中间的值也在寄存器中表示，测量点由模块的分辨率决定。这种内部转换也适用于0-20 mA输入范围。所选择的输入信号类型是通过短接模块的可移动端子块中的特定端子硬件配置的。提供两个距离跳线，一个用于信道一和信道二，另一个用于信道三和信道四。

【英文介绍】

The IC693ALG221 is an analog input module that is part of a series of 90-30 Programmable Logic control (PLC) systems. The module is a component module with analog input function. The module has four (4) input channels that receive 0-20 mA and 4-20 mA input signals from field equipment and instruments. The module is equipped with an internal analog-to-digital converter (ADC) that enables the PLC to process and further regulate the signals used in the user program.

The IC693ALG221 has a 12-bit input resolution of 4µa (1 LSB = 4µa) per input range for 4-20 mA input signals and 5µa (1 LSB = 5µa) for 0-20 mA input signals. It has an absolute accuracy of 0.1% full scale + 0.1% reading and a common-mode voltage of 200V. In addition, the module has a linearity of < 1 least significant bit and an input filter response of 325 Hz.

The default channel of IC693ALG221 is 4 to 20ma. When a 4-20ma signal is received, the module internally converts the signal range to 0-32000, which is a unitless measurement representing the value of the input register. 0 corresponds to 4ma and 32000 corresponds to 20ma. The intermediate value is also represented in the register, and the measurement point is determined by the resolution of the module. This internal conversion also works in the 0-20 mA input range. The selected input signal type is configured by specific terminal hardware in the removable terminal block of the shorting module. Two range jumpers are provided, one for channels one and two, and the other for channels three and four.
