【功能描述】

IC693ALG220在工作温度下的典型绝对精度为+/-10 mV/40µA，而最大值为+/-30 mV/160µA。它的线性度为1最小有效位(LSB)，输入滤波器响应为17 Hz，模块隔离在场侧和逻辑侧之间为1500伏，跨通道抑制> 80 db，电压模式下输入阻抗> 9兆欧，电流模式下输入阻抗> 250欧姆。

IC693ALG220模块是GE发那科公司的模拟输入模块，是90-30系列的一部分。该输入模块是可编程逻辑控制器(PLC)的一个组件，带有4个输入通道。每个通道都可以根据用户的应用要求轻松地将模拟信号转换为数字信号。此外，GE Fanuc IC693ALG220 CAV输入模块允许用户转换输入信号范围为-10到+10伏。每个通道的转换速度约为1毫秒。因此，IC693ALG220输入模块一次为任何通道提供约4毫秒的更新速率。转换后的信号具有12位二进制的分辨率。

GE Fanuc IC693ALG220输入模块配备了有限电流输入模式，以及每个通道用户终端连接器上的跳线。用户可以使用跳线将内部250欧姆的分流电阻连接到电路上。该分流电阻允许输入范围为-40至+40毫安。然而，用户必须不断监测输入电流，以防止输入电阻自热，因为这可能会对电流精度产生负面影响。GE Fanuc IC693ALG220 CAV输入模块主电源采用隔离+24伏直流电源，由PLC供电。电压通过稳压器/逆变器发送，产生IC693ALG220模块工作所需的电压。IC693ALG220输入模块带有一个LED，显示其运行状态。

IC693ALG220 模数转换器模拟输入模块

The IC693ALG220 is a 90-30 series module formerly manufactured by GE Fanuc and now owned by Emerson Automation. The module is mainly used as an analog input module, compatible with the input signal range of -10vdc to + 10vdc. The module is optionally compatible with 0-20 mA signals, which can be enabled by installing 250 ohms on the module's user terminal connector.

The IC693ALG220 is equipped with an analog-to-digital converter (ADC) with a voltage input conversion resolution of 12 bits. The 10-bit is a current input that can be increased to 11 bits using a precision resistor. Each channel of the module has a separate update rate of 4 ms, while the module is powered by 24VDC provided by a PLC power supply. It has a backplane current consumption of 27 mA from the +5 volt bus on the backplane and 98 mA from the isolated +24 volt backplane bus. It is installed in any available I/O slot of the 5 - or 10-slot series 90-30 baseplate and occupies a single slot of the rack.

The typical absolute accuracy of the IC693ALG220 at operating temperature is +/-10 mV/40µA, while the maximum is +/-30 mV/160µA. It has a linearity of 1 minimum significant bit (LSB), an input filter response of 17 Hz, module isolation of 1500 volts between the field side and the logical side, cross-channel rejection > 80 db, input impedance > 9 megohm in voltage mode, and input impedance > 250 ohms in current mode.

The IC693ALG220 module is GE Fanuc's analog input module, part of the 90-30 series. The input module is a component of the programmable logic controller (PLC) with 4 input channels. Each channel can easily convert analog signals to digital signals according to the user's application requirements. In addition, the GE Fanuc IC693ALG220 CAV input module allows the user to convert the input signal range from -10 to +10 volts. The conversion speed of each channel is about 1 millisecond. As a result, the IC693ALG220 input module provides an update rate of about 4 milliseconds for any channel at a time. The converted signal has a 12-bit binary resolution.

The GE Fanuc IC693ALG220 input module is equipped with a limited current input mode, as well as a jumper on each channel user terminal connector. The user can use a jumper to connect the internal 250 ohm shunt resistor to the circuit. The shunt resistor allows an input range of -40 to +40 mA. However, the user must constantly monitor the input current to prevent the input resistance from self-heating, as this can negatively affect the current accuracy. GE Fanuc IC693ALG220 CAV Input module uses isolated +24 volt DC power supply and is powered by PLC. The voltage is sent through the regulator/inverter to generate the voltage required for the IC693ALG220 module to operate. The IC693ALG220 input module has an LED that shows its operating status.
